I can't distinguish colors on Salifert test and as was mentioned the scale is not that useful. So, I switched to the Nyos phosphate test and find it much easier to use and the range is appropriate.

That is a lot of light. Can’t tell what coral you have up top, maybe a cup or duncan and an sps? My thought would be to Try backing it down an hour to start, but keep a close eye on your coral. If they start to fade may need to bump it back up.

Now that we know there is an algae issue we may want to go back to gfo or chemi pure blue.

Let’s get a second opinion before making changes. Never hurts to get some more eyes and thoughts, especially if we can get the great folks with #reefsquad here

@Mastiffsrule I think you have done an excellent job and covered all the bases.All I can do now is bump the thread.

Sorry if I missed this, how long have you been running the MH and which watt?

I would back off maybe a hour a week so nothing gets to shocked. If not already, I would run the cfl on a reverse photosynthesis period. This way you get benefit of some additional ph stabilization and the water is not getting hit in the dt and sump at same time.

13 hrs. 400W MH with following bulb.

Already reverse. The CFL kicks on in the fuge when the MH goes off

The only thing that I might add is to keep track of the age of your bulb. Some metal halides will degrade over time and the light that they give out will start to shine on the warm side.I will see an increase in nuisance algae when this starts to happen.

I use the magnificent anemone to judge how healthy my tank is.

Never got into nems. They freak me out. Why are the moving, where are they going? There’s no mall in your tank is there?
