How much GFO?
Hi all,
I have been doing a lot of reading about GFO recently and I have been struggling to find a rule as far as how much to use.
I have been having algae issues of late and seem to have a constant brown film on my sand bed which is driving me nuts.
I have been running carbon and GFO in a BRS dual reactor for a couple of years and have always followed the BRS calculator, but it seems like it asks for a lot of both for a 90g tank.
Some sites have mentioned that the amounts that BRS recommends are way off base, so I'm curious as to what rules you follow.
How much do you use per gallon (or whatever measurement you use)?
I have also been vodka/vinegar dosing but nothing seems to be happening to my levels, and in the last few days a couple of my corals have started looking a bit pale. Others still look great.
