? RE: dual channel pump for slow water changes

[jimmyj7090]

Hi Randy, thanks for speaking today.

I was wondering, you mentioned a dual channel pump in your presentation that could be used for slow constant water changes, what pump were you referring to? was it the
"Aqua-medic reef doser twin" or another pump?

Thanks

I use a 30 gallon per day, dual head Reef filler pump:

You're welcome.

Sounds interesting, please elaborate.....

It pumps water into my sump from my saltwater reservoir at 30 gpd, and at the same time, removes 30 gpd from my tank and sends it to a drain. So it is an automatic water change, and is slow enough that I don't bother to heat or adjust the new salt water at all.

Your doing 30gpd in waterchanges! That must get really expensive.

I only run it once in a while.

Do you put it on a timer so that you don't deplete the replacement water but yet continue to pump out the tank?

Sounds like a pretty good plan. I'm guessing that the flow into the sump and the suction are at opposite ends to help prevent from drawing out the new water?

I just plug it in for a while, then unplug it. A timer would be a better fail-safe for my forgetfulness.

I actually draw from the sump andadd to a refugium that is distant from it.

Thats agood idea. I used to do a fw drip on my freshwater tanks, and i never had to do manual waterchanges. This is pretty close, I like it.
