I am running the SeaGel from Seachem (carbon and GFO
). I used it b/c I just dosed my tank w/ Chemi-Clean last week and it is back already. I changed all of the DI
cartridges and my prefilter. They were done. I also changed out my membrane. I had the water tested before the unit and after. Before it was .85 for PO4
and .0 after the unit. I am running two DI
canisers b/c of my municipal water supply is terrible. I have way too much stuff to take it out and redo the aquascape. I have a ball of grape culerpa in my refugium about the size of a volleyball. I can see that it is growing, slowly. I do have some bio-balls in my sump acting as a baffle and a bubble trap. I was thinking of changing over to something else, maybe some live rock rubble. Any other suggestions? TIA!!
