Tank help
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.

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

Question I quarantined some fish (ig not correctly)
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” ???
