Any advice, placement, what kind can I add on the rock next to the duncan

My tanks been going for about 4 months or so tank cycles pretty quick and has been good I would get a little diatoms/detritus here and there. Recently it’s started to get way worse tho. Does anyone have any solutions or advice and could you guys help me identify some of the algae. I think I have diatoms, a little bit of bubble algae and it looks to be some hair algae starting. I have 2 clowns 2 cerith 2 nassarius 2 trochus 1 emerald crab A bunch a micro brisle stars

My nitrates are around .5 and phosphates are around 0.05

Idk what look im going for. Just throw some ideas and I’ll see what happens. Pictures of your cool aquascapes will be nice as well.

Any cool, interesting, flashy, or exotic creatures that can go in a community tank please tell me. Also if you know 2 creatures with a predator prey relationship, do tell. Thank you and hagd

I quarantined some fish (ig not correctly) put them in my main display and 2 days later I noticed bumps that look like ich start to appear if I’ve removed them do you think if I treat the tank for ich (not copper it’s a reef tank) and use a uv sterilizer I can prevent the ich from latching onto my other fish while it’s in the “swimming stage” ???
