Q: How is this used exactly? is it genuinely effective at reducing nitrate levels? my ammonia and nitrite levels are a perfect 0ppm. thank you!

Yes it does work I used it for months without an issue. My levels reduced as tap water was high I got a 75% reduction but don’t take that as you will get the same results

Q: I have a sponge filter (shrimp tank) with nowhere to put this in the filter. Can I just put it directly into the tank?

Yes although it's not ideal. Generally bacterial media is kept free of stritus by mechanical filter media, you can't do that if it's lose in the tank. If you have choice I'd certainly give it a go and see how it works.

Q: May I put 4l in a fluval fx6 to replace filter media ?

I tried this about 12 months ago not worth the money at all didn’t make much difference to my water quality and most the media is hard grey stone which is basically just stone and has no use in your filter at all. My advice would be go with alphagrog e25 as it’s only £23 for 20 kg and is much better I now have a mix of alphagrog and bio home ultimate and won’t look back. This is just my opinion good look with what ever media you choose to go with
