Dosing pump

[Rutrag]

How about a dual dosing pump run by the drive port?
I think a dosing pump is my next equipment investment. I’m holding out for one that I can hook right into the Hydros 4.

I use Intllab dosing pumps with the drive ports. I had to make some cables to hook them up. They don't come dual head though. The flow rate is adjustable using the pot on the front. They are around $26 Each. Photo below shows the pump and one of the cables I made.
