Hi everyone. I'm new to this site and have been looking into building a sump system. I am starting a small fishroom tanks to go with my existing tanks. In the end I will have 5 discus tanks maybe a 6th 75 gallon added soon.

2- 75 gallon But will probably get one more 75
1- 90 gallon
2- 33 gallon tanks.

My question is, how big of sump do i need to have once the bulkheads are drilled and plumbed in and how big of return pump would I need to pump back to all the tanks. Would everything work better if tanks were side by side or does it matter if I have tanks stacked 2 high...Also I know that titanium heaters should be used. How many 500-800 watt heaters with a controller would i need to get my desired level of about 86 degrees. Also what size bulkhead and pipe/tube size would be best to use 1/2, 3/4 1 inch??? Any help would be appreciated...and thanks.
