Hey, guys, I'm a reefer from Brazil. My 300L tank is one and a half year old and I can't get rid of these goddam brown stuff on my sandbed. I've tried almost everything to remove these algae and nothing seems to work. I use natural sea water for water changes, but every now and then, when it's necessary, i mix my own water using RODI and aquaforest reef salt. I used to start NSW to lessen the cost of salt and also because it helped me once to get rid of these algae for one month or so.
I'm running GFO (Phosphate Minus from Aquaforest) to keep PO4 levels steady at 0.03 (readings from salifert test). My silicate levels are very low (0,03), and I make sure by testing my RODI water with salifert silicate test as well. Nitrate is not an issue, since they vary from 2 to 5. The other params are steady, within the recommended for reeftanks.
Lights are on for 8 hours a day, of which 2 hours are only in blue lights. Flow (2 jebao RW8) is also okay, since it can't be to strong, due to my tank being a LPS reef.
Even though I'm facing this scenario, All my fish and corals are fine.
Any thoughts?
