Efficient and maintenance-free, these durable, corrosion-proof automatic chlorinators and brominators are ideal for Newer existing pools or spas and work automatically with your pump and filter system. Review: Simple trouble free way to add chlorine to your pool. - The Product was an easy install. Took less than an hour and is working great. The install time includes building an elevated position so that the unit's top sits above the water level. The input tube was installed where the line from the pump goes into the filter head. I put the output on the return fitting at the pool. The one negative I saw in many other comments was how hard it was to remove the cap to add more chlorine. I suspect they are tightening the cap too much. This is an O-ring seal, which doesn't need to be tightened hardly at all. The pressure in the unit will cause the o-ring to deform sealing it. Once the pump is turned off the pressure drops, the o-ring goes back to its original profile. Just put the cap on until it touches the o-ring and then maybe tighten another couple of degrees. If you are worried about a leak, just turn the pump on and look. If its leaking, very unlikely, then turn off and tighten just a little more. I've added chlorine 4 times so far and it has been finger tighten off and on. No wrench or pliers needed. Review: Better than a floater. - easy to connect,hard to open.Better than the pentair. ## Features - Uses 3-Inch diameter Tricolor S tablets - Dial control valve lets you control and adjust the rate of feed - Easy-Lok threaded cover for safe and convenient access to add tablets - Unique finger-release catch provides extra security - Simple installation for do-it-yourselfers.

Took less than an hour and is working great. The install time includes building an elevated position so that the unit's top sits above the water level. The input tube was installed where the line from the pump goes into the filter head. I put the output on the return fitting at the pool. The one negative I saw in many other comments was how hard it was to remove the cap to add more chlorine. I suspect they are tightening the cap too much.

No wrench or pliers needed. ### ⭐⭐⭐⭐⭐ Better than a floater. *by S***T on November 3, 2018* easy to connect,hard to open.Better than the pentair. ### ⭐⭐⭐ Chlorinates well, lid sticks, tubing is garbage. *by D***M on January 19, 2026* After using it for six months, I can tell you a couple of things. The lid is very hard to open. Use care to just barely tighten it -- and even when you do, you'll probably get it too tight, especially if you haven't opened it in a few weeks. I screwed mine into the concrete slab, but since the chlorinator rotates in the base, you don't have any leverage to turn the lid without turning the whole unit. This makes it much harder to remove the lid. Right now I'm ordering a pair of strap wrenches, which I hope will help (two of them, one to hold the unit still, the other to turn the lid) Take a look at the other comments for the person who mentioned getting PTFE tubing. After just six months, I can confirm that the black plastic tubing that comes with the chlorinator will get brittle and break. It's worthless. In trying to loosen the lid, today I cracked the feed line. I'm going to take the advice of that other reviewer and order the PTFE tubing and hope for a better result. I should have done it in the first place. Shame on Hayward for including that cheap plastic tubing which will, without a doubt, fail within months. On the plus side, I will say that the chlorinator has worked very well since I installed it six months ago. My pool is chlorinated nicely and stays clean, usually with the filter about 3/8 open. It holds enough chlorine tabs to keep my pool chlorinated for a month or more. I was worried that ordering the smaller one might be a mistake, but it's been perfectly adequate for my average-sized in-ground pool. ## Frequently Bought Together - Hayward CL110 Off-line Automatic Chemical Feeder,Black - 2 Sets Offline Feeder Connection Pack with Saddle Clamp Chlorinator Feeder Hose Tubing Parts with 2 Sets Check Valve Control Valve for CL200 CL220 Offline Replacement --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/5000753-cl110-off-line-automatic-chemical-feeder-black](https://www.desertcart.vu/products/5000753-cl110-off-line-automatic-chemical-feeder-black) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-12*
