When I do scrape the brown off the glass it takes a while for it to come off. I siphoned it off the sand one time and about a week later it came back.
I feed once a day alternating between frozen mysis, brine shrimp and flakes. My lights turn on @ 10am. @ 7pm I turn off the white and switch on the moonlight. Too much light you think?
I don't have a TDS
meter but I will look into that very soon.
The purple looks like cyno, the brown is def diatoms. Try and keep the glass as clean as possible, that's so you can see your fish! Lol.
I would maybe go to feeding every other day for the time being, until you can get your diatoms under control. Also meant to ask, your skimmer, is it pulling out as much as you feed? It should be a close measurement. If you feed and add say 1/3 cup of food, you should be pulling that out daily. It may just need a little longer to pull out the protein, hence feeding half as much.
Your light schedule should be fine, maybe start at 11 vs 10 just to help really jump start the reduction in phosphates. It's kind of a real pain and there's no fast way to just get rid of it all unfortunately. Oh on the cyno, if you siphon it will come right off the rock. Very easy to clean that, the diatoms will be the biggest issue.
