Posted this earlier in a forum no one could reply too....

Im smart, "S"M"R"T"


I have been thinking about making some reef friendly tanks in my spare time, I was wondering if you reefers could give me some needed input...

I was thinking of making some moderate sized tanks, sized for nice reef displays, please give any and all input!

What are you thoughts on these sizes?

LengthxDepthxHeight
24x20x20
24x24x20
24x24x24
30x20x20
30x24x24
36x20x20
36x24x20
36x24x24
36x24x30

Also, what style of overflows are prefered?

Would black back tanks be a desirable feature?

All tanks would be constructed of the highest quality cell cast acrylic, with a wall thickness greater than standard store tanks.

I greatly appreciate your input!!!
