Hooking up a 3rd tank to the system

[SeaHorse_Fanatic]

If you do this (which I personally don't recommend right now), then you should add a much larger sump since if the power goes out, the overflows will be draining water from the top layer of two tanks and could overwhelm the excess carrying capacity of a small sump.

Next time you're over we can draw up a few possibilities but since this tank was just set up, I would sit back and enjoy it for the summer and consider an upgrade farther down the road. A large part of the enjoyment of this hobby is to relax and let things grow, rather than constantly tinkering and upgrading (which is fun but 2 months is too soon IMO to upgrade).

Cheers,

Anthony
