SPS Question...

most montis like lower flow... i have had once that had no polyp extension before because the flow was too much, they eventually lost that tissue.

Reserve the higher flows for acros and put the monti's in the lower flow areas

 

You have more flow than I have in my 200g, and I grow SPS like weeds.

The params all look good, but IIRC those are the stock bulbs in that NOVA, right?
If so, switching the actinics to ati blue + will make a huge difference, so would going to ati, or geisseman aquablues.

RTN just happens. But usually only 1 colony will go, and not a whole lot of them.

 

lol Eric, didnt believe me about already having enough flow
you will be fine

 

I have about 34X in my current tank and have moved the pumps around so my corals will grow up instead of short and stumpy.

 

Hmmm Well thats a mind reliever I guess!

Now to just pick out the corals and look into a controller
