I am using the included bag with all the RowaPhos in it in a 75G tank. I read the directions (And while suprisingly vague) I discerned that one must consider po4
bound in rock and sand. After doing some reading this was initially not a concern for me but I read one comment regarding some bacteria/animals removing the o2
atoms and freeing the po4
again. So, I went with the idea that since my readings were initially so high, I suspect bound or soon to be un bound, if you will, I would treat using the whole 250ml in a bag. As for flow I purchased a new Aquaclear 110 which is freggin perfect for bags and I placed it directly in the out flow. Water must pass through it to get out. I did run it on the lowest setting intially but couple days ago I jacked it up all the way. As of today Salifert shows less than .03
, closer to .01 and Red Sea shows, well best it can, less than .1. Not a real granular test kit that red Sea ; ) My only guess is that maybe it works slower than the SeaChem as the SeaChem made a real large dent in about 4 days. I would still like to try maybe Kent Marine or Two Little fishes if someone can attest that it won't bleach my corals : ( Crazy as it sounds I am considering letting the toadstool recover a little more and using the Seachem at about half the dose for a much shorter time to try to put the knock out punch on the algea. While po4
has decreased, the algea seems to be getting a little thicker again. With the SeaChem it was really looking sickly. Suggestions?
