Any thread on these?
Id like to get a few if they work well. could i set them up for auto water change or will the lose calibration too quickly? I only want to change I half a gallon day.

I e looked at these also and am wondering. Maybe post this in the lighting/filtration equipment section?

Hmmm, interesting and a nice price, I look forward to a couple reviews...

Guess it would work good as a top off. Otherwise you'd have to add an accurate timer. Also Says it doses 15-70ml per minute, but some stuff I only dose 5ml per day, so timer would have to be down to the second.

yes, Reefkeeper. has second timers. also you could dilute your solutions!

Bought a similiar one a while back. Kinda okay as an emergency backup but a terrible use of a 20 bill eitherway.

What made it so terrible?
