Hi. I had my reef set up for almost 10 month with no problems considering I moved home 2 months ago, if any thing my parameters are more stable after I removed all the rock and cleaned my sand when I moved, more to the point I'm still having problems with diatoms, pictures below,
Lights are on 8-9 hours, 2x Whites 24w t5 and 2x hybrids 60% blue, 40% white 24w t5
- below 1
Temp- 27 - 28°c I do have trouble keeping the temp down but never goes over 28.5.
- 120- low but have started buffering slowly
Iv heard and read that silica is the main cause of diatoms but my tank has been running long enough now that I would of thought the diatoms would of burnt it's self out, I also thought it could of been the salt mix I was using but now I change the brand of salt mix every few months and still have this problem, I don't over feed and keep tank very clean as I have a basic setup,
175 l bow corner tank
Fluval 205 canister filter
2x power heads 24kg l/r
2" sand bed
Hope that's enough info, I'm really stuck on this, iv also done hours of reading on this problem but the answers are always the same ( I have silica in my tank ) but how???? I do 20% p/w every 2 weeks
Any know what I'm doing wrong?
