How to plumb in frag tank with no drilling.

[Jake_the_reefer]

So I have a weird project I want to try and I'm not even sure it is possible so I am reaching out for ideas. What I want to do is possibly plumb in a custom 10g frag tank into my nuvo 20g tank without having to drill it. What are some possible ways to do this? I know it a Longshot but still worth a shot

There are hang on overflows. You’ll need to start the flow by sucking air out of the overflow tubes but they’re generally pretty reliable

HOB overflow.. check out the Eshopps PF 300, have been using for months with no problem. 29 gallon running 20 gallon sump.

You can install aqua auto's smart level sensor ($60) to prevent overflows in the case of a siphon break. If the water ever reaches the high level sensor in the DT, it shuts off the pump.

I have a larger model echoes hob on my frag tank and I love it. Never had an issue with it loosing it's priming
