Just a question about my tank. I have a 125 gallon tank that you have probably seen pics on my 125 log post. Recently there have been white strands of something that looks like 'thick hair'. I have no idea what this is but it is all over ALL of my live rock. Only on the rock.
I have some dark brown forming on my new pvc
closed loops but the sand and rocks are pretty clean.
I use RODI
water and do a change of 30 gallons once a month. Nitrates are around 15ppm. Ammonia/Nitrite are at zero. Calcium was at 350. I dosed with kents liquid calcium three capfuls over a few days.. which equals about 2-3 ounces I believe. I need about 9 onces to bring the calcium up to 415.
Is this a result of the calcium dosing?
