Hello all,
I have a 90g tank that is reef ready with a 20g sump. I inject presurized co2, via a mj1200 with a needle wheel mod. I beleive the co2 is disolving pretty wheel, at least I dont see many bubbles in the tank. All of the plants I have are growing good but not great, and still have yet to have any pealing. This tank is lighted with 2 T-5ho retrofit kits, for a total of 4-36''(39w) bulbs with individual reflectors. Currently there are 2 18k Daylight bulbs and 2 6500K plant bulbs.

My question is with a total of 156 watts or 1.73 wpg, is this considered moderate to strong lighting?
I know im loosing Co2 threw my sump, but do I need to up injection?

Tanks Specs

-90g reef ready aquarium
-20g sump, only filled with bio-balls and filter floss W/ 750gph return pump
-30lbs of flourite, 40lbs of eco-complete, 30lbs of SMS (soon adding 2 bags of flourit and 1 bag of eco-complete)
-Mj1200 w/mesh mod for Co2 difusion
-2- T-5ho retro kits, total of 156watts at 1.73 wpg

And 2 more things:
- How tall is that tank?
- How long is your photoperiod?

The tank is a standard 90g which is almost 25'' tall. The photoperiod is set via timer at 12hours. This tank was previously a saltwater tank, and the bulbs are all Hagen Glo series bulbs. The LFS I work part time at is going to be getting in the Geismann bulbs shortly and I plan on switching mine out to both the midday and aquaflora.

Can I hook up a canister filter to a standard reef ready tank, its the megaflow series. Or would I have to modify it?

I extended the drain tube going to the sump so it expells the water at the bottom of the sump. Half of the sump is packed from the top to bottom with bio-balls, I guess there in there for more of a mechanical filter.
