From my experience with planted tanks, I think I need some kind of check valve for the hoses that connect from the rio12HF return pumps inside the third bay of the sump that leads to the top of the tank 52" inches off the ground.

The rio12HF returns the water into the clean bay when I turn off the return pump to prevent from the water in the tank from overflowing ---> check valve?

There is a difference in flow of GPH vs Flow in current. You can still have large GPH flow with lower current by changing diameter. Still even for lazy catfish, and Id think depending on what catfish you have, they are all heavy waste producers. So the higher turnover rate of 10 times an hour is still better for them and much healthier for them as well.

Chizzle is correct though that the flow rate your mentioning for each of the pumps you mention is the zero head pressure rating. Roughly with your head height of about 3ft your Rio is only putting out 450-500gph an hour max. The Eco 2300 is rated at 2300 liters NOT gallons as per the manufacture specifation and this would be at zero head height. ------ 2300 litres Per hour = 507 GPH. So by the time you get the 3ft head height your only pushing around 200gph.




TO the OP I cant say enough good things about the Laguna pumps. VERY quiet, VERY efficent in electricity. Draws less. VERY reliable. They have a very high output you can fine ture with your system. For 180 gallons Id recommend exactly what Chizzle said. You should end up with around 10x turn over. If your looking to get a second pump as one for backup in case of a failure. Then get a second laguna to match. The other thing is Laguna pumps are reasonably priced. Im not a rep or anything for them Just can tell you of my own personal and recent experinces. This is coming from someone thats used Several other brands out there for years.

The eco is actually pushing 1890 gph at 0 head hight and 1250 at 4 ft.
 
I have a laguna. 9000lph at zero head 7500 at 5 foot so about 10x turnover on my 180. would definitely recommend for the same reasons stated above. minebis split at output into 2 streams so I don't have crazy flow in 1 direction.

Daniel did great! he was able to re-arrange my sump so the drain will be fast enough to keep up with the two rio hf12s return pumps pumping 1230 gph combined. He even glued the piping so theres no air pressure leak, set the water level so the return pumps will not overpower the drain pipes to avoid from ever running dry, and tested the drain pipe so if the power goes out the water will will overflow my sump for water on the deck. I specially like the part he told me to angle the return nozzles up top so air is present to avoid the return pumps from siphoning the water back into the sump. I don't need to buy a check valve. He saved me 2-3 hours from having to return to the fish store and exchanging into a y split configuration. The service only asked for $20bucks it was about two hours; i thought what he did to educate me was worth more than that so I doubled his asking price. Awesome job! Back to my remaining hours of freedom before work tomorrow. Thank you Daniel!
