I just setup my new 93g cube, running the following: caibbsea Fiji pink sand, BRS pukani dry rock, instant ocean salt.
I calibrated my Neptune apex using the supplied regent last night and it's been reading 8.6 all night.
No lights are running as the rock is still curing and has been for three weeks, I've done two 100% water changes, with the last one being about four days ago.
I have never had pH this high ever in any tank I've had over the past twenty years, hence the reason of my post as I am at a loss.
