Question on Reef Ready Tanks

[HippieSmell]

How do y'all get so much muck in your overflows? Maybe I haven't left a tank running long enough between upgrades.

My tank will not overflow without a backup. My tank can take the sump volume should the drains get clogged and the sump can take what would drain down in the event of a pump outage.

How big is your sump? It must be quite small or you are running a low water level in the DT if the main tank can handle all of the return flow from the sump should your drain becomes clogged. I know it must not be if as you said,the sump can hold the water when the pump is off.
Have you tested these sanerio's?

I didn't glue my overflows into the bulkheads to prevent this. Just reach in and pull one out, the waterfall will push everything down the drain..

Good trick. Thanks.

It is a 40b sump. The return section is sized to be just big enough to hold the return pump (eheim 1262). The most water that would be pumped up is less than 2 gallons. The 125g tank can handle that. I have tested all failure scenarios. Draining down from the tank is tested all the time when I clean it and turn the pump off.

I reality, with 2 independent gravity fed drains, there is really no chance I'd ever have a scenario where the drains both failed at the same time. Statistically, I suppose it is possible, but in practice, this situation would never occur.
