GHA phosphate rx

[sturner91]

Was looking for some insight before I dose my tank with phosphate rx. I currently and have been running gfo, carbon, dosing vodka and running biopellets. My GHA has not let up at all, if anything maybe worsened. Nitrates test at 0 and phosphate always at .25. I pull off as much GHA as possible during water change and suck up the floaters, but it's always a struggle to pull the hair off.

I found phosphate rx based off a YouTube video, some die hard fan. Did a little research and seems reputable.

Does anyone have a reason why I should not use this?


I understand tackling the problem causing my problem needs to be accomplished, which is has. At first I was overfeeding. Since learning this is a general cause I've cut back drastically. In addition, trying to add as little phosphates to the water I've been feeding strictly frozen food that gets thawed in Rodi water.

Your dosing and have a lot going on with your tank I wouldn't dose another thing Gfo should be able to reduce phosphates. I went from 2.00 to .1 in 7 days. I would add an algae blennie there great at eating gha

I have a lawn mower blenny in there already. Also refreshed my snail supply.
The vodka did its thing helping me with my Nitrate issue. I'm at the point of weaning down to find a good spot with 5-10ppm of nitrates.

My main goal with the phosphate rx is to nuke all phosphate in the tank to hopefully loosen the GHA grip so I can pull it off easier.

What size is your tank. Do you have sand in the tank if so how deep.

Once your nitrate rises your phosphate will drop. The problem right now is you are nitrate limited. When carbon dosing you have to have some nitrate to reduce phosphate. Its called the red field ratio, or the rate at which bacteria consume nitrate carbon and phosphate.

To make it simple nitrate is removed faster than phosphate so maintaining a small amount of nitrate <3ppm will allow phosphate to be removed continuously when carbon dosing.

If you are dead set on using Phosphate RX only use a half dose for your tank and put a 10 micron filter sock on the drain into your sump. You will be dosing lanthanum chloride and it causes the phosphate to form tiny crystals that can be removed by the filter sock. Otherwise you will be spreading phosphate crystals throughout your system.

Funny, I have almost the exact opposite problem. Phosphates always sit at 0 but my nitrates run high.

Other than that, same GHA, same dosing, same biopellets, etc...

If your phosphate limited nitrate wont be pulled, it works both ways. Try feeding a little more. It seems to help with the Bio Pellets.

I generally don't feed Reef Chili/Reef Roids but I'm going to start feeding a bit in hopes that it will raise my Phosphate enough that I'm no longer limited and the dosing/pellets start to work

remember: change GFO medium monthly: it saturates
