I bought this product for a 70 gal AquaClear hanging filter on a 50 gallon freshwater tank to end an algae bloom. It had no effect on the algae bloom after 3 weeks. I bought a 9 watt Green Killing Machine filter and the bloom went away after 7 days. Since the bloom went away, regular non-bloom algae is growing fast on the rocks and ornaments under LED lights. Whether or not this product removes phosphates, it does not seem to stop algae growth under normal lighting and feeding conditions. I had high hopes that phosphate removal would control algae, but this doesn't do that so buy it for other reasons and not to end or even slow algae. I have a big bag of it in the filter. 2 stars instead of 1 because I can't say it doesn't remove phosphates, but it doesn't do what some people claim.

Buy PhosGuard, 2 L / 67.6 oz. Now

Been using it three weeks going on four. No change at all using it in a reactor as directed. Now I'm looking for a better brand

I was running low on this product as I use it with my saltwater fish tank. This product is great at reducing the algae that we have in the tank by getting rid of the phosphates in the water column. Just rinse and change it every other week.

I run this mixed with black diamond carbon in my phosban reactor, and I have no detectable phosphates. I use 1.5 times the recommend amount, and I change it on the first of ever month.
