Kahlauzz, I know you have run Rowaphos in the past how much did you use in your 77 as mine is a 75.....not sure what my phosphates are but I don't have any algae problems just that I read that rowaphos can lower it to .o3 or better.....which is my aim. I think I am less than one...maybe .50 or so.
It isn't a real hob filter it is an old aquaclear 70 that I modded into a mini refuge by cutting it up.....there is a small area that holds about 2 c of carbon and will fit a like sized bag of rowaphos. I will pick some up tomorrow......
