i just never read where put holes so i think ill bump it to a foot and a half for peice of mind.

in case ur curious the reason i have a 4inch is im sik of spending for ever useing a half inch hose on my 180. and correct me if im wrong a 4inch hole should do around 9600gph

i gravel vac on saturdays and due just a water change mid week

I would expect it to do that atleast, 14,400 gph or 240 gallons per minute is what a 4 inch pipe is rated at for suction or gravity pressure. depending on the quality of the valve you get it may be alot less or pretty close.

Does your tank have built in overflow boxes? Have you considered holes in the top of the tank instead?

You know a 2" hole flows more water than two 1" holes. You may want to increase the diameter and go with less over all holes. You get the best of both worlds, less holes and more flow.
You should sketch up your overall plan and show us what your thinking about?

i just wanted skimming across the back of the tank. if someone knows somthing better please tell me. i want to send my tank in early next week to get drilled.

Is it an acrylic tank? If you don't have internal overflow boxes, have you considered external overflow boxes?

its glass, i planned to have bulkheads running to the sump.

Look into glass-holes.com overflows. I think they work great. Don't re-invent the wheel, just use what works.

i just dont want anything in my tank whats so ever. and to get 10x rate it would cost 665 dollars.
im doing a closed loop with multiple intakes. i think ill just do one hole on one side of the tank. it seemss like im confusing the people who know more then i do.

should i use bio balls or scrubbies. i could care les about cost i just want to know what works the best.
