SunSun JUP-01 9W UV Sterilizer Submersible Filter Pump

I was running the Fluval 306 canister and the Aqueon Quiet Flow 20 together on my 27gal cube tank. My tank is over stocked, but with small fish. It's my daughters tank in her room. I could never keep the water clear without add some chemical to the water every few days. I was using Acurel-F to clear up the water and it did work, but like I said I would have to use it every few days. I got the SunSun JUP-01 and installed it in the tank right away. I really didn't pay any attention to the tank for the rest of the day. Installed it around 2pm and got my daughter ready for bed at 8pm the water was a lot clear. The water always has a little cloudiness in it. Not a green tint. With the LED lights you can see if the water has any milky cloud in it easily. This morning I got my daughter ready for school and fed the fish and wow the water was clear. The only thing is I wish this had a water flow control to slow it down a little. 27gal cube the water flow of this thing is close to the output of my Fluval 306 canister. 18 fish in a fresh water 27gal tank and they don't look like they are being blown around. The air valve is kind of useless to have. It will blow air into the tank, but it makes a lot of small bubbles that float around all over the tank. In mot sure why that is an added feature. Another thing is the suction cups. They should have made tabs to easily remove the JUP-01 suction cups from the glass. When it's stuck to the glass, it's stuck to the glass. Not easy to remove. But all in all I have to say, it works.. For how long, who knows. UPDATE... Its been about a week now or better. I use to have to do a 25% or 50% water change a week when cleaning the tank. Looks like I don't have to do a thing to it now. Water is very clear. I don't see any reason to vacuum the rocks. My tank is over stocked and between the Fluval 306 and the SunSun looks like my tank is now stable. The SunSun is still working, I see the little window to check the light and its still on. Another UPDATE... Well the SUNSUN still works, but my daughter wanted a few more fish. I started watching the tank a little more and seen the fish were being blown around a little. I unplugged the SUNSUN and seen yeah it is the output is a little too much. Maybe my tank is too small for the water flow that is coming out of the SUNSUN. My tank is 20x20x20x20 in size, 27 gallon cube. On a 20gallon long or tall might be better for the SUNSUN. Like I said I wish it had a water output adjustment on it. Nothing wrong with the SUNSUN JUP-01. I bought the Aquatop UVE-9 because it has a water flow adjustment. I might get another tank and still use the SUNSUN on that.

I am giving this item 5 stars, not because it cleared my tank, because it has kept my tank crystal clear since adding it to it. We have a 65 gallon aquarium, we recently made a boo boo and our tank got bacteria bloom, the water looked like someone had dropped a box of Alka Seltzer in it, so very cloudy. I did some research, went out and bought live plants, Nitrogen remover, nothing worked. So I ordered this, did not have any idea what wattage I should buy, just desperate. It came in the mail, put it in the tank, noticed nothing the first day, the next day, only noticed a slight clearing where the filter was, next day no change. Maybe I was not patient enough, but my daughter and I had the feeling we should do a partial water change. We drained about 50 percent of the water out of the tank, refilled it, treated the water, and have been running this filter on a timer 8 hours a day. I cannot believe how beautiful the tank looks. The water is so clear. Just beautiful!!!! I would recommend getting one, the maintenance and stress are now gone. I am about to order another one for my quarantine tank.

I have a well established 29 gallon fresh water tank with an AquaClear 30 and a standard undergravel filter. Everything had been going great for several years and then two month's ago I had a huge algae bloom and my water turned green. I have tried changing the water several times and turned off the light for over a week and the green water just keeps coming back. After reading about UV sterilizers I thought I would give it a try. When the package arrived on Monday (5 days ago) I opened the box, and took the filter apart to check the quartz tube and o-rings before putting in my tank. Like some of the other reviewers, I noticed some grease on the tube but this was easily wiped off. Having dealt with o-rings in plumbing and pools for awhile I know the grease is required for a good assembly. After the inspection I placed the filter (Sterilizer) in the tank and noticed I could not see it at the back of the tank because of the green water. By the next morning there was a noticeable clearing of the water and I could now make out the outline of the filter in the back of the tank. Over the next 3 days the tank cleared up more and more each day and this morning the tank is crystal clear :) There are a few issues with the filter... it is bigger than expected, and the force of the water coming out is way stronger than any powerhead I have, it blows the fish around. I am going to figure out a way to plug some of the output to reduce the flow and also put it on a timer to run several hours a day from now on. I will update this review after I have had it for several months.

Day one in top of pic and day 4 in bottom. (Day 4 I added a couple more plants and did a 20% water change) I am happy with this product! Only 4 star because the instructions were kind of vague and there’s a part not attached that I don’t know what its use is but it works fine without it. As other reviews have said, take apart the glass and take out the rubber or plastic spacer and If there’s a stream of bubbles after it’s plugged in just put your finger over the blue air valve on top a few times until it stops. I’m sure you take chances when purchasing this product but in my case I had excellent results in getting free floating algae to disappear. COMPLETELY clear water at day 5. I will revise this review if I run into any issues.

Just got this today, Read all the reviews and many people told me about getting one to be cloudy. Numbers are ok and my Tank is about a month old. It's a 60 Gallon and so far it's blowing out powerful and I like it so far. I'll update in a while, I posted some pic's from today,I'll update later. Today is 12/1/2018.... UPDATE****2/27/19 Just looked at the bottom of this UV filter and after only a couple months the bulb was burned out. If you buy this make sure you get extra bulbs. I don't know why so quick but in the beginning it did help my tank well lately my tank is starting to get cloudy so I looked at the bottom and the light was barely blinking which should have been on constant. I am happy with it but not happy about already replacing the bulb....... UPDATE****3/30/19.....NOW THIS UV FILTER IS BARLEY WORKING. IT DOES WORK AND HAS WORKED BUT IT'S THE END OF MARCH AND FOR IT TO BARLEY PUMP AND AIR OUT ISNT GOOD. I'VE CLEANED IT OUT AND IT'S STILL THE SAME. NEEDS TO BE A WARRENTY ON THIS!!

Update: after I was given a new replacement, that one also died on me within 6 months or so. I contacted CLL Supplies about it and was told to replace the "head thing" whatever that means. I wrote back asking for clarification and couldn't even get that. I would not purchase this item because it will probably fail on you every 6 months. After they give you a replacement, you're screwed because there won't be anymore replacements from that point. Buyer beware! I purchased this device last summer and it recently died on me. I have cleaned it weekly and don't know why it died! I tried replacing the bulb and that didn't work either. Oh, I didn't get the blue piece that goes on the top of the device where it shoots water back out after being sterilized. /: No instructions were included in case it were to stop working. It was an EXCELLENT device when it worked. It died for no reason! I could have had a defective model or it just wasn't made to last a year or longer. Oh, and it's only in a 40 gallon tank. It's not like it was overloaded in a huge tank.

My previous UV Light went out, couldn't find bulb to replace it so I took a chance on this model. My aquarium is 37 gal deep. It was so super green algae bloom, dense green, also nuisance snails abounded, the environment for my fish was dire at best. ☹😟🤢😪😔. I did no water changes at all! I simply installed the filter as instructed. I was working long hours, I had neither time nor energy for water changes. After 24 hrs there was almost no difference. Then, on the 3rd day 😲😲😯😳🙂WHAMMOOO!! THE WATER looked miraculously clearer, by day 4 and beyond,,,well its amazing! The snail population has also practically disappeared! I promise the pictures/ video are NOT FAKE! THE force of water that is expelled by this device is quite significant. I felt (although very amusing to watch the fish play in the current) long term may stress the fish too much. This is what I did: I have an Orchid betta, (beautiful fish fyi), anyway he came in a big plastic cup, which I placed upside down over the exhaust port. The forceful water swirls inside the cup, loses force then goes out the bottom, which is, obviously the sides of the filter helping keep debris away from it too. I also have loaches (eel kind) they can get into any little slit. So I put a large filter bag over the bottom to prevent them from getting into the filter (maybe they won't get a tan but it will keep them safe...lol. ha ha.) I have live plants, the leaves do get into things, So I always keep intakes covered with filter bags. Remember if you do the cup thing don't block it with too small a cup, leave plenty of space so the jet of water flows n swirls freely. I am very pleased so far,😁 although I've only had it about a week, the fish all are happy and healthy. Well my two large Angelfish bicker a lot, but they lay eggs from time to time, so I guess they are just like an old bickering married couple...lol he he😂🤣😅ha ha! My large algae eater he doesn't like any other fish around where its cleaning. But its a hard worker so we'll let him be...😆 🤣 Oh I have a lid on my aquarium keeps the cup on the filter, otherwise the force would blow it off.

First Amazon product review and I was very happy to submit it. This product out preformed what I expect it to. I was 100% satisfied with my purchase. I've been in this hobby for a few years now learning as I go with planted tanks and I have overcome most problems except for the green water algae blooms that wreck your water for weeks. I wish I would have had this piece of equipment for those sort of problems way back when so I could have avoided all the hassles. The pictures I provided were from a smaller tank I had that had a sudden algae bloom of green water from a LED light I was testing from my 55 gallon tank. The UV sterilizer made quick work of the problem over 5 days without a water change. Once the problem was fixed I removed the sterilizer until it is needed again. Once again great product for such a small investment in this hobby. P. S. I did a little research regarding planted tanks and any negative effects on the beneficial bacteria. As far as I could find out most of the beneficial bacteria that does the work resides within your filter media and only a small amount is affected in the water column. But if this is a major concern, then please do your own research to further satisfy your inquiries.

Buen producto si ayudo a aclarar el agua de mi acuario

Great product unbelievable what a uv light can do to water. My pound water used to become green every summer due to access sunlight and floating algae. In 5 days the uv sterilizer cleared the pond on all the floating algae. Now my water has become crystal clear. Looks like clean water from a fresh water steam.
