Couldn't you pump CO2 straight into the res?

Personally, I hate having to deal with it multiple times a day, but I can't afford to spend $1500 on a professional doser system. The following system is only an acid doser, however with some tinkering you could likely make it both acid and base capable, however I will not cover that. Making it function as an acid doser is a simple process that will be extremely easy for anyone. Items needed: 1. Milwaukee Rating: 5

I'm not that smart. How would you do it? I plugged the meter and probe in the electrical and the meter won't come on. I might have a bad meter.

Did you also plug in the ac adapter? There are two things that look like ac adapters ;-) They both need to be plugged in.

It's totally worth the money to me. Let us know how it works

yeah, I plugged the thing in piggy back style.

You didn't plug the ac adapter into the other thing that looks like an ac adapter, did you? They both need to be plugged in separately.

doh! Yeah, I plugged one into the other. I'll try it your way if you insist!

[mountainman]

lol

Yeah, if you plug one into the other, it'll never work. The one with the outlet on it is what you plug your pump or CO2 control into.
