EA Premium Phosphate Reducer Filter Pad 18x10 - Cut to Fit for Aquariums and Pond

this was a good filter pad, i was able to make 2 for my Sump's filter trays out of this pad, simply cut to fit with a razor knife or scissors. it WILL slowly reduce the phosphate levels as described. one pad section of about 8x10" reduced the phosphate levels from a bit over 2ppm to between 0.5-0.75ppm over about a weeks time- as that was my target range I pulled the pad then. It's not something I'll need to use all the time but I'll likely pick up another package to have on hand in case i need it.

This has been a great addition to my canister filter system. I saw an improvement in algae control and water quality.

This really helps with cleaning up my fish tank! The algae was out of control, even after water change and vigorous vacuuming! I'm using it with a marine land cartridge filter as the second slot! Only wish it was a bit larger as a sheet so I could get 4 sections out of it

This stuff is fantastic. I've had it in my sump, after the floss, and within a week my phosphate levels went from 2500+ down to about 500. I can only imagine that after a short while longer, the readings will be nil.

Great price

Placed a small cut piece into my reef protein skimmer for a 100gal along with similar cut out pads from a phosphorous and ammonia sheet. Not sure what a few of these reviewers are on about, claiming this stuff didn't/doesn't display results? Did they really attempt to give these pads a try? My apologies for not having a before n after results as I too, thought this would be a waste of $ and time, however, I was wrong. My entire tank, corals, macro algae and rocks were all covered in very dark brown coloration, likely Dinoflagellates. Overnight with a total tank blackout, woke up in the morning to find a cloudy brown tank and all browning of my DT items mentioned above cleared! The only thing that was left is protein skimming and collecting this brown funk water. later in the day, my water has nearly crystalled cleared....amazing and a relief!

Summers in Western PA see an increase in the amount of phosphorous in our municipal water. This product purports to help lower the phosphorus levels that promote algae growth. It’s a huge pad. Just cut it to fit your application. This works okay but not as well as well as granular phosphate-removing filter media IMO. It’s more difficult to determine exactly how much of the pad to use for a given aquarium size. Very much trial and error.

Nice filter pad, easy cut to fit my filter. Seems to do what it says.
