Then used marineland silicone 6 bucks. The most expensive part is the overflow and return pump but you can find them cheap. Definitely worth it IMO
. I dont have to stare at my protein skimmer, heater and filter the whole time. I also added some filter media in between the baffles for extra filtration.
My only concern with the siphon "powered" overflows is if the siphon is lost...biiiiig mess awaits. I saw somewhere online where someone made a failsafe that basically cut off the return pump if the water got too low in the sump, but I can't find it.
Seeing as how my first SW
tank is going to be a 20G setup, having the "dirty work" under the tank, rather than in it, is a big consideration for me. I just need to figure out how to make a failsafe overflow.
