Phos-Zorb 150 grams - 3 pk
Everything you read will tell you phosphate will not harm fish. NOT SO !!! Even though I test my water every week I lost hundreds of dollars of fish. Within a couple of days 95% of each new order was lost. I did have a severe algae problem nothing worked; not AlgaeFix and not 50% water changes. The test kit did NOT have a test for Phosphates. Lo an behold; when I tested for phosphate mine was out of sight ! the max was 10 ppm on the test card which is a dark blue, mine was almost black. I then tested my tap water and it was not as bad but still over 10 ppm. I put two Phos-Zorb packets in my 155 gal tank and the next day the reading was between 10 ppm and 5ppm. Ordered new fish and they are doing great. After 4 days my readings are between 2 ppm and 1 pp. This is a truly great product.

Lowers phosphates - aquarium is algae free
My aquarium water is crystal clear and algae free. Since I have freshwater, my goal isn't to get my phosphate level down to 0 - test readings are always very low. Phosphates as such are not really harmful to freshwater fish. I use one pouch in my filter for a 75 gallon aquarium (not enough room for two). I feel this product is safer for my fish than some of the other products available. Nothing leaches out into the aquarium water. Love the low price here on Drs. Foster and Smith. I always have this on hand.
Note: only use this product is you do not use a phosphate buffer.

My aquariums have had algae blooms for a long time now. Tried everything. While shopping for light bulbs I saw this product. Understanding that algae blooms can be caused by phosphates and high organics, this product really caught my eye. Phos-Ban has been in my filters for 5 days now and my tank water looks beautiful. Crystal clear, oxygenated ! My fish also seem to be very happy.
I suggest anyone who is setting up a planted aquarium to use this product for awhile, if you are using planting substrate. I never had problems until I switched from river gravel to planting substrates.

Works as indicated
Just as the description of product says, phosphate levels drop by day five and continue for two to three months. Great control of algae!
