And...
-Would you say a 4000 LPH [~1000 GPH] pump is the right amount of power, not enough, or more than needed?
-Would you say (1) 600w bulb is the right amount, not enough, or more than needed?
-And if either of these are more than needed, what is the minimum you could suffice with?
I am legitimately considering building this, but smaller to fit in my area. I was considering doing a 2.5 foot diameter, instead of 4; thinking about a 500 GPH pump thats considerably cheaper, instead of ordering an expensive 1000 GPH pump; and using a 400w, instead of a 600w.
