So far things are working out nicely.
The corals are in a re-tasked 55g. I put it where the counter top is going to go. Above it are the two radion's for the 120 tank.
Purchased the pipe and fittings for plumbing in the 120.
Silicone the last section on the 75g sump
Silicone half of the overflow box.
Got my dual head Stenner pump for my Auto-W/C project.
Next:
Silicone outside edge of overflow box.
Purchase many feet of 1/4 rigid hose to connect pump/tank tank/drain. (Thinking if I keep the 55g on the counter that I might make the Stenner put the water into the QT... but was worried about water sitting inside the piping for too long with out air/circulation anything that might get pulled in would contaminate the water.)
Re-Think purchasing a EB-4 to place by mixing station to control Stenner pump, also to make it quieter around DT area, as some people said it is a noisy pump. (need to purchase a 30+ foot USB cable then)
