Some of my corals, namely red lobo, water melon acan, and purple plate started to bleach without me realising. Now I have to temporarily off my two PAR38 to prevent further bleaching. Think its due to the strong lightings from the PAR38 LED.
I have filter comb installed but bits & pieces of it still able to flow thru it. Thinking of putting in mineral mud & a thin layer of live sand on top as substrate for refugium. Wondering if that would help?
How do u place/contain/tied the chaeto without it being blown away?
Cos right now i'm tying it to acrylic sheet using fishing string & use a small LR as counter weight on it.
Maybe my flow in my sump a bit too strong.
Just wondering if the refugium glass surface started to grow coraline algae & other algaes, need to scrap off? cos i saw some ppl's refugium tank glass surface is quite clean. Afraid it will kill some of the pods if i scrap it off.
Hope somebody can give me advice on this.
