Thanks.
It is a regular 180 aga with dual overflows. I am going to use one hole in each one for a return and the other for a return from my sump. I am going to point them down to the respective corners to keep them stirred up.
I have one tunze 6011.10 on the 90 that I am upgrading from already and will be using that. The return from my sump is a mag24 coming from 10feet below in the basement.
So, with those two circulation things going, I think that I am going to have 3 or four holes drilled into the back/middle area for a closed loop. This way, I can put the closed loop on a timer to shut down at night, thus lessening the flow for the night, while not completely eliminating it because I'll have the one tunze and my returns going.
Does this sound acceptable? I just need to find out what pump I will use for the closed loop to give me the gph I need.
Let's see... a 180 tank. The tunze is about 1900gph
The Mag 24 at 10ft is about 1000 gph.
Any experience with the pump that I need for the closed loop would be greatly appreciated. I would rather spend alittle more now and be happy.
Thanks for reading
