3.5 months in and absolutely no bryopsis in the tank. No algae of any kind. Only some Cyno.
When I had bryopsis I was always battling phosphates. I had to use tons of gfo to control phosphates that were off the chart. Since I have rid the tank of bryopsis and the subsequent water changes my phosphates have been below .01ppm. I have not used gfo in 4 months. Nitrates are also at 0. I have a very low bio-load in this tank. Only a couple sps , several very large frogspawn one fish and 2 shrimp.
I used to always think that the phosphates was stored in the rocks and in the deep sand bed. It appears that the phosphates in the tank were stored in the algae in the tank. Once I rid the tank of the algae the phosphates are gone. This is good news because I was worried that I was going to have to take all the rocks and the sand out and cook the rocks to rid the tank of the phosphates.
