ENHANCED PHOSPHATE ELIMINATION – Phosphat-E Phosphate Remover is a potent solution to assist in phosphate control in heavily-stocked aquaria. It provides a quick and precise solution to elevated phosphate concentrations while being safe for all inhabitants of reef and marine-fish-only aquaria
AQUARIUM PHOSPHATE REDUCTION – This marine water treatment eliminates reactive phosphate immediately, once added to the aquarium. It is powerful and highly efficient and can be used on an ongoing basis for the phosphate reduction process
QUALITY ASSURANCE – After treatment, phosphate test kits may show false positive readings as a result of the chemical mechanism of the kits, and the aquarium may become slightly cloudy when the product is first applied. This is normal and temporary and does not mean the product is not working
DIRECTIONS – Test aquarium phosphate concentration before initial use with an accurate kit. Add Phosphat-E near a mechanical filter or protein skimmer intake and administer at a maximum rate of 2.5 ml per 20 gallons daily. This removes 0.5 ppm of phosphate; 250 ml treats up to 4,000 US-gallons

While some customers consider it a great buy, others find it expensive.

Amazing Stuff
I have a 300 gallon mixed reef and the phosphate level got away from me probably due to overfeeding. When I bought the Phosphat-E, the level tested with a Hanna Checker was 1.9 ppm.Having read so many excellent reviews and only a few negative ones, I felt that the overall product is good, but also decided to go slow just as the instructions state. It provides a maximum dose, but I saw absolutely no reason to take a chance since it saws its best to lower the phosphate level over 7-8 days.The simple math indicated a total (max) of 37.5 mls per day, but I started with 10 mls split into 3 doses, morning, midday and early evening. No negative results at all and the next day I couldnât believe that some of the closed polyps were beginning to open back up. I increased the dose to 12 mls for the next 3 days and after 4 days, I tested and the level had dropped to .09. I again increased the dose to 16mls as the corals are looking so much better. The phosphate level at day 6 is now .06 and I am confident in following the âgo slowâ approach per the instructions. I should mention that I also cut down the feeding quantity and although fish will eat all day if you feed them, they are still happy. ðOverall great product, easy to use, and I highly recommend.

Dosing instructions are confusing
This stuff might be great, I canât tell yet, but I have a real issue with the dosing instructions. First, I understand the dose is based on the amount of desired phosphate reduction in a given volume of water. I get that. But you have to do the math to figure out the correct dose. âEach ml eliminates 1ppm phosphate in 4 gallons of water.â Ok, I have 40 net gallons of water in my tank and I want to reduce my phosphate by 0.2ppm. Whatâs my dose? I have to do math to figure that out. I donât want to do math. I want to read a chart that did the math for me. Nope. They donât provide one, not even on the web page. Still, I can do the math to figure out my dose. 1 ml will remove 1 ppm in 4 gallons of water. So…1 ml will remove 0.5 ppm in 8 gallons1 ml will remove 0.25 ppm in 16 gallons1 ml will remove 0.125 ppm in 32 gallons1 capful (5 ml) will remove 0.6 ppm in 32 gallons. Hereâs where my dosing goes south on me. The directions on the bottle also say 5 ml will remove 1ppm in 40 gallons of water. How can 5ml remove .6 ppm in 32 gallons and 1.0 ppm in 40 gallons? If only that had a, whatâs it called, oh yeah, A CHART!***two treatments later***I still donât like the instructions and all my earlier complaints about determining the correct amount of liquid to use but…the stuff worked. Like, totally worked. According to my API phosphate test my levels have gone from >1.0 ppm to unmeasurable. Nothingâs died in the tank and Iâm happy with the outcome.

Easy and affordably brings down phosphates.
I’ve struggling with phosphates for awhile now and did all the things, aggressive water changes, all sorts of filtering and feeding changes etc. This stuff had me back to near zero in no time and suddenly corals are growing again. Well I shouldn’t say no time, I had no change after the first several days, then it dropped dramatically to not measurable very quickly. As far as I can tell there’s no downside.

Works great for lowering phosphates in my 75g reef. I drip it straight into my skimmer and it makes the skimmer go crazy. I’ve tried gfo and refugium but I like this method the best and it did the best job at lowering phosphates. Lasted me months so far

Removes phosphates well…however MUST follow instructions…DO NOT dump directly in tank!
