Thinking of redoing my plumbing

[Bob Parkins]

Thinking about it...

Currently I have a separate pump running my chiller. For the sake of noise
I have it on the temp controller with the chiller. I know it isn't good for
the pump. My return pump is a Mag7 as well.

I was thinking, in order to eliminate the chiller pump altogether, (Marc's
Idea) .... of using a T off the return pump and diverting some of it to the
chiller.... and returning chiller water to the return area. (currently
pumped from return-chill-return & works nicely).

My concern is how much this might reduce the flow for both return (to tank)
and to chiller. Thoughts or ideas?

Hi Bob,

My thought is for you to try it and see how it all runs. If you hate it, you
can upgrade your return pump to a stronger one, or switch it back to the way it
was. :)

what pump have you got that pumps 3000 gallons per hour?

>Dolphin pumps Ampmaster 3000 pumps over 3000 gallons/hr according to
the manufacturers flowchart at a 4 foot pressure head. My tank is set
up to deliver the water through a "T" fitting near the top of the tank
into opposite corners of a symmetric hex tank. Even though this seems
like alot of flow, the arrangement of the outflow does not direct the
flow onto any LR or corals, so all flow onto LR, and corals is
indirect.
