Haha. Yeah the tank is 3 months old. I started with dry rock. I won't add live rock or mud because I won't risk any undesirable hitchhikers. Every coral I get goes through a rigorous cleaning both physical and chemical in an attempts to make sure that nothing foreign enters the system. I don't have any worms, aptasia, or vimited snails of any kind. I've had all of those issues in previous builds and did not want that with this one.OMG I am on the same wavelength as @Rick5 AGAIN.
The rock, shall we say, does not look well aged. How old is this system? Dead or live rock start?
Ur numbers are fine, just keep doing what ur doing. PO4 up to .1 is just fine as are nitrates at 10 and the rest. The biome just looks a tad young to me & Rick.
The one caveat to that is that I took the cleanest 10 lb of rock from my previous tank, scrubbed it down thoroughly and inspected for any pests. Once I felt confident that there was nothing invasive on it I put it in the sump. So technically I guess I did start with some live rock.
