my 29 gallon build, pics, and advice needed.

[gfk]

So I am upgrading my Tank from a 20 gallon high to a 29 gallon, with drilled internal overflow, and 10 gallon sump.


Right now my tank is up and has water in it, here it is.

i have a 1 1/4" bulkhead for a drain and a mag 5 for return. My skimmer is a corallife super skimmer 65.

My return is not what i want so im going to hard plumb it with pvc.

My overflow is where i have a question. Here it is:

here is the full setup for now

my question is, if i make my overflow slots bigger, would that allow me to turn my return pump up a little more? i dont feel like im getting enough flow through the sump/ off the surface, and my return line is barely spitting out any water in order to keep my last column in my sump at a balanced level. Also, the water barely is going over the slits, so would widening them help, or adding more water, or what?

well how much flow do u have right now? i mean u really dont need THAT much cause are those 620's or 820's? i mean i have one 820 in my tank and im at like 27x turn over and thats enough to keep anyhing i wanted but to have all that and the return pump? might be overkill(IMHO)whatever u want though cause u might be doing something else i dont know but as for the overflow it shouldnt be going over the teeth to much and u should be able to turn up the pump a little more and the overflow should take it fine,well how big is the pipe that might be the problem!

the return pipe is 1/2 inch and the drain is 3/4".

when i turn the pump up, it sucks the water level down in the last champer. maybe i am over reacting and its overflowing fast enough and i just dont think it is.

and the seios dont seem to put off much flow, but maybe im used to direct flow and not dispersed flow

i honestly dont know crud about pipe size but theres a overflow calculator on the homepage

ya thats probably it i like seios for that very reason the corals seem to like it more to!
