So most of my rock is slightly red/Brown with bunch of these patches of some kind of algae. Any idea what it is and how to fight it?
Tank is about 2 months old. Parameters are good with exception of nitrates. Trying to get it down to zero. Was about 20 and did a 50% WC on Tuesday. Reading about 10 now. Ph stays around 7.8. I’m dosing 2 part. Alk 9, ca 430.
Some browness later in the day in the sandbed too. A few weeks ago I think I had a diatom issue and was able to blow most off the rock and cut my lights back a bit. This doesn’t blow off but I can scrub it off with a toothbrush pretty easily.
Edit
Pulled some off my return pump nozzle and it’s actual more green than brown
