FW sump ! input, ideas, ???, exp wanted

Hi everyone, I am looking into building a sump for my 75g and am excited about it. I have been doing a lot of research and putting bits of info together to come up with a plan. I would really like to hear about what some of you have done. Please dont tell me to look on utube, done that, for hours. Finding usefull info on how to go about planing out a FW sump has been to say the least very fustrating.
Where I'm at.....did a flow chart of what i want, building my own stand to hold 75g display tank a 20g QT and am using a 40g breeder for my sump, going with a wet/dry and refugium sump.
I have done a search on this site about this topic and the results were very disapointing, many questions never got replyed to. I hope this thread will take off and help many people in the future.

I highly recommend you play with your existing 40g and 20g and setup a test system. Much better to have a woops (flood) in the garage then in a living area with the 75g.

If it were me I would use a 30g plastic storage container for a refugium (for plants) and a smaller sotrage container for the actual sump. In that way the refugium can run at an almost full water level and the water level varies from evaporation in the smaller sump container.


(but then I also would recommend a planted tank anyway)

I would make a pvc overflow. Which can even be done if the tank is not drilled. If you need some ideas I can provide.

Then I would test the system to insure:

1) power out does not flood the sump.

2) power return results in normal operation.

3) overflow failure does not result in the upper container (tank usually) flooding.

I forgot 3 and had a couple of floods. The key is the sump runs dry before the upper container floods.

I can provide some rough sketches if you like. But bottom line is to play with the smaller system until you understand what is going on and you get no floods.

But even all that is just my .02

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)
