After weeks of work my DIY fish tank is almost done :D

It's a DIY 65 gallon glass tank plus stand plus sump plus twin pump and twin overflow one system collects water near water surface the other one much deaper.
first overflow (overflow A) looks like this one


the other overflow (overflow B)looks like this one



The system is working fine now however I have a water flow issue to adress, when both pumps are one the same level overflow A drains much more water than overflow B, the resulting water output is insufficient for both pumps to operate.
If I lower overflow B the issue is resolved however I run the risk of overflooding the floor besides electricity goes out for 1-2 minutes twice to three times everyday, when electricity goes out water level should drop by 1-2 inches if I put overflows on different levels, so what modifications would you suggest to overflow B ?
I can put two overflows like overflow A but I would prefer pumping water at different levels

If you can't lower it than you'll have to rebuild it with larger pvc or restrict pump flow or go with smaller pumps. I would just rebuild it with larger pvc

Quite some craftsmanship...but i'm just wondering, wouldn't a öne-pump-system be a better option?
The big pipes are surely thick enough for that, imho.
I'm just thinking, if you have one deep drainage system, when the system fails, gravity may pull the water out of the tank,, until the sump is full, and then start to fill your room....

Could you post more pics, esp so we can see the whole system?
I only use 2" pipes to push the water from the last sump-chamber into the tank, and an overflow-chamber flows the water back into the sump, when the maximum level is reached.
When power fails, the sump will fill, to the max, but then i allways keep a full tank of water and deffo have no water on my floor, least of all, too little water for my fish left!
