Which Dosing unit to buy?

What's the risk? so if a pump stop working, the calcium or the alkalinity will get lower...so what? this cannot screw up a tank anyway. before I was using the dosing pump my alkalinity sometimes went down to 5 and none of my coral were affected, including the sps. I had alkalinité and calcium swings.

The only complain I have with the marine magic is that if there is a power outage the unit does not resume automatic dosing by itself and time must be set again and it must be put into auto mode. The settings for the pumps however are kept into memory so no need to reprogram them.

But hey...150$ plus 20$ shipping, can't beat that!

I have to agree with the poster above. You obviously havent had a tank that uses these big 3 elements like a heavily populated SPS tank. A drop like mentioned above is on the verge of a crash which is a big deal!
