I talked with the guy at my LFS
and he said that if the clearmax looks like GFO
, it likely is. His supplier of GFO
for their tanks told him that its all the same stuff, just used in different ways. A reactor would be best, but the Fluval 305 method will also work. He seems to think my brown whispy algae is from the white eggcrate.
They feel the eggcrate leaches silicates into the water, and that I have an issue with silicates rather than phosphates. They took alot of eggcrate and after cleaning it, they let it soak in some large tanks of water for a few weeks. They said that after the soak, the water (originally RO
water) tested very high for silicates. They promptly removed ALL eggcrate from their store.
I will remove the eggcrate and give the Fluval 305+clearmax a few weeks to see if things get better before going the reactor route.
