Is 10 inches enough?

:laugh: I wish I had asked this question sooner. Last night I hung a 150 watt MH Sunpod 10 inches over the water of my 20G long. I want to do clams. Is this the right height? Edited by sen5241b

Too..........many.........jokes........head........hurting!

 

I don't think you will be able to determine a "right" height. Best way would be to get a par meter to determine your light levels on the sand bed.

Thx --In some places the rock is near the surface allowing me to place a clam higher --within, say, 12 inches of the light.

That might be a little too close, but should be ok. I would only move it up if the tank gets too warm.

 

I had a 150w MH over a 30g and I had it about 12inches above the water. I Never had a problem growing anything in it.

I think I have my 250 MH about a foot above my tank (30 x 30 cube). I'd think you could go a little higher. Espeially since the tank is so shallow. Whatever you do, monitor your critters closely for signs that they're getting too much light and adjust accordingly.

I would move to about 20 inches up and then move it down if needed you can never be to careful .

My clowns have been uncharacteristically laying on the rocks although when I throw red sushi roe in the tank they dart towards it. I will monitor.

Seriously -I had this same sunpod sitting over a biocube 29 only 3 or 4 inches above the water. Clams, zoas and many softies did fine. Plates were fine BUT some LPS burned no matter where I put them in the tank
