Multi Tank Sump Systems

[dean9922]

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.

Dean the size of sump depends on the size of return pumps you go with and the size of bulkheads depends on how much water you want returned to the sump. A 500 gph return pump may lose a lot of head pressure when you are pumping it through an entire room but initially it still sucks a fair amount of water from the sump. If you are using this all for discus then you don't need a lot of water flow but the very smallest I would go with for returns is 1 inch pvc. The size and number of heaters depends on what the room temperature is, if the room temp is 70F and you want to raise it to 86F then you have to provide enough heaters to warm the tank volume by 16F. It may be easier to heat each individual tank rather than heat the sump water and then deal with cooling as its pumped through the room etc. As far as side by side or stacked tanks, I would go with side by side if you can, stacking tanks means keeping enough room between the bottom of the upper tank and the top of the lower tank to allow for working on both tanks with out banging your head PLUS you'll lose head pressure on your return pump if you go with stacked tanks.

also should take into account the amount of water that might back flow from the displays in the event of a power outage, maintenance, etc when sizing your sump.

thanks Mark.....that is the problem....i know nothing about this stuff...pump size, PVC size etc etc...lol
I need "lots" of advise....

One more question...is it better to just run a sump system on maybe just 2 tanks instead of 5. Just a thought.....would prefer to incorporate the 5 tanks....
