i do have him put higher in my tank now could that be a problem?

but my candy apple's are higher and doing great ! with my sps.

Need more tests
Ie
Alk
Mag
Cal

And what are u useing for lights. Looks like a lot of algae on the glass id test your phos too.

its around 6 months old now. been having a phos problem.. cleared up for a while and i bought a bunch of snails that didnt go well and now i got algae.
il do my tests right now.

phoso 1-2 between
calcium :560
Hardness : 17.5
Nitrate : 0
PH: 8.2

this is weird because i buy all pre mixed water and use ro water only :S

Your cal is way hi and alk should be 7-8 dkh or 2.5-2.9 meq/l so that's way hi too. Your phos can come from useing rock that was saturated with dead stuff.

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.

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

You have slime then it's not good and no weekly personal choice cuz I also don't skim I do 30% or more weekly. Not enough macro in my fuge to accommodate the food I add. So I think 25% bi weekly is to little.
