🔧 PhosGuard, 4 Liter / 1 gallon Review

Easier to use than GFO and I think it suits my tank better! It's a good deal and cheap enough that you can change it out fairly often, unlike the GFO where I always used it for too long because I didn't want to waste it.

I use Fosguard in my media reactors (2) in the swamp. This is great for keeping phosphate levels down in my 120 gallon reef tank. I use a Hanna meter to test phosphates. I change my medium every few weeks so this larger bucket is perfect for me.

I bought this product to reduce phosphorus in my aquarium. The recommended dosage is 100 ml per 60 US gallons. After a week, he reduced his phosphate levels by about 80%. With weekly water changes, the phosphorus content remains constant. The only question is how long the product will work before a change is required.

My aquariums have problems with silicates in tap water and therefore seaweed - this product solves that problem and keeps my plants clean and green. I keep chicken, angelfish, measles, barbs, neon snails and mystery snails and the product does not affect them in any way. I'm a big fan of the Seachem line of aquarium care, water treatment and plant fertilizers.

Cured my cyano/algae problems in my 32 Biocube in three days. Also now using it in my 20 gallon fresh water tank with no side effects. I recommend the Nano Reactor Saltwater Tank and use reusable bags in my external freshwater filter. Love sensible discounts when buying in bulk, so keep up the good work Amazon! I will keep this on my must have reef aquarium list.
