what size tank is that
how many pounds of sand do you have
how many pounds of rock do you have?
 
29 gallon tank. 20 lbs of that agro-sand, 20 lbs live rock
 
Is that a glass door next to the tank?
 
if that's 20 lbs of rock you may want 40 more lbs.........

there is not much rock surface area those must be some dense rock.....
 
Yes. and teh tank is in front of a window. However the blinds aren't normally open. But it's been nice the last few days
 
I think you just found the source of your algae bloom.
 
lol i concur. Let me ask this too. How long should my 10,000k and actinics be on during the day?
 
The funny thing is, I know nothing about saltwater :) I will let the experts help you with that. I would hate to say something that would affect your livestock, etc. that I am not familiar with.

But, algae is algae. I would keep the blinds closed...and even then, you may have to add heavy curtains. You might still get a lot of light through and around the blinds.

Good luck :)

The two rocks on the left side are a little dense but the rest is porous and light. I plan on getting more most definately. Should I look for light weight peices?
