sweet where are you located at?
Is the system all natural light? What are you using for filtration? It looks like it's going to be a very nice system.
Cool. Details please.
You also can try out the WP60. I have two of them on my 8' long tank. The wave it generates is unbelievable. By the way I also have two MP60. The MP60 has wider flow. The wp60 is also cheaper is about 1/7 of cost of a MP60.
So what happens if it rains?
You will be surprised with the wp60s. I have 2 wp40s on a 7' tank and 1 would have been enough and a couple of power heads on steady. Great tank, good luck!
Are you going to use a skimmer? What return pump are you running? Where are your overflows? Or how does your water get down to the sump?
