good, but WARNING!!! by Tim

Comments: The pumping mechanism is great and works perfectly, even for tiny doses (like 1 drop). HOWEVER, I have a big problem with the design...the programming is ridiculous, I'm not even sure I want to keep the thing. It only allows you to program in "cycles," not by a clock. In other words, you can only have it dose, say, once per day, every hour, every half-hour, every 10 mins, every 5 hours...whatever "cycle" you want. IT WILL NOT LET YOU dose for only certain parts of the 24 hour day, say night-time. For example, I'd like to dose kalkwasser every hour from 10PM until 8AM, but there is no possible way to do this. If you think you can just set the whole system on a timer itself (so that it would only be powered at night), this won't work...the system resets after a power outage and you have to do a sort of soft reset (by pressing two buttons simultaneously) to have it start the programs again. The pumping operation is a perfect answer for dosing, but due to the lack of programming ability, I don't recommend this product, you'll only get frustrated trying to figure out how to "time" things for a decent "cycle." I would not recommend this product to my friends.

Great, but use check valve! by Paul

Comments: I was ready to return this unit as useless until I finally noticed the Tips and Tricks section of the product page here on Marine Depot! The manual doesn't tell you this: If you install the pump where it is above your source, you MUST use a check valve on the INPUT side (the manual shows the check valve on the output side). Without the check valve, the pump is never able to draw the additive up out of the reservoir, it just goes up one inch, then right back down, over and over. So, it's not nearly as foolproof as the LitreMeter III I run on my other tank, but at less than half the price, I'd say it's worth the hassle factor. The physical build quality of this unit is impressive, better in fact than the much more expensive LitreMeter. Yes, I would recommend this product to my friends.

Comments: The aqua medic works extremely well when setup properly. Instructions are not the best but they have a help number which is useful. Can program pumps individually and deliver the volume based on elapsed time since pump is of one speed. In power failures you must restart but program remins intact in memory. Best pumping system I have ever used. Yes, I would recommend this product to my friends.

Great

Good but over priced by Chuckb

Comments: Somewhat difficult to program (1980's technology) but reliable and accurate. For what you get a bit expensive but no problems in 6 months I would not recommend this product to my friends.
