Great to hear!!! Be careful I give this warning now. ITS VERY ADDICTIVE...
I have decided to take the plunge into SW.
Ok. back to the topic at hand.
What are you keeping in the 55 now. Are they cichlids? Just curious cause I have a feeling in a year or so that 150 is gonna be salty also. haha Thats how addictive this is...
OK so you want to go FOWLR
. In a 55 gal
tank I would suggest 50-75lbs of LR
. Now you dont have to get all that rock at once. You could get it in 1/2 now and 1/2 later on. As far as your DSB
a good depth to shoot for is 4-5".
Since this is gonna be a FOWLR
I would suggest maybe 2 55W PC
blubs at 10K for this tank. I personally prefer 10K bulbs as they put out a bit more white light than 6500K You should have enough light to support anything that comes on your LR
in the way of mushrooms or poylps. If you want to encurage some nice coraline growth then toss a 4" NO actinic bulb in there also.
If you have a DSB
there is really no need for the Fluval unless you just use it for water movement.
