Help on zoa's not opening

Seen this before and it's all on your water. Not lighting unless your bulbs were old!!!!!! Then that'll cause your algae on top of bad quality water.

I hate testing my tanks so I do weekly water changes of 25% or more but nanos are prone to spikes depending on how you feed and what your keeping. To much phyto and it can make the parameters jump a bit and if its going up daily well then you know what your doing wrong.

I would just start doing more water changes and start from there.

For evaporation your roping off with fresh water right? I have to ask.

[darkreef]

yes always fresh. i put more fresh in the tank then salt ( no cover ). i do a 25% biweekly il start doing it every 4 days until the problem clears up. just started getting that red slime and i knew something was wrong and ran to the forms. so i blow my live rock off daily.. it snows pretty bad. so il blow the rocks everyday and water change every 4
