FluvalClear Max Phosphate Remover 300g - 3 x 100g - treats 3 x 100L,Brown

I got enough carbon too last my 2 canister filters for over a year. Total 1200 ltrs per hour on 2x150 ltr tanks. Good deal,find smaller bags if you need them. Better than pre-made filter media.

Working really well. They are large bags so had to cable tie them around my small filter instead of them being inside. But this still sucks the water through them and filters nicely. One had been in for nearly two weeks and has reduced the Black Beard algae massively. Still a way to go yet but very impressed so far.

I used this in my pond filter. Works as it should all good.GA e 4 stars not 5 as the bag is in the large container and when you try to remove it it is partly buried and a load of carbon goes on the floor.The bag is very big. I guess big enough for 800g but I want to use it 90g at a time. So there's a lot of extra bag to try and keep control of when loading into the filter.Other than that it's all good.

It arrived on time. Keeps the water clear. value for money

Buy this instead of pre-made bags! Had it so long & only 1/3 way down tub & I have 4 tanks with 1 build in secluded filter & 4 canister filters. Good quality carbon, not too large or small particles nor are they too dirty when rinsing. Comes with one large bag. Easy to use, instructions & info on jar, defo value for £.

quality item

Nice wish there we're bigger sizes

The product itself is fine. I expected a few mesh bags with pull ties but received one giant mesh bag. Bigger than my entire external filter. Had to buy mesh bags separately, more waiting time. Incorrectly advertised here as bagS.
