I just 3 of the SE Lumen Max Elite reflectors and I'm going to hang them about 10"-12" off the water. Should I get the glass bottoms for each pendant? I just don't want the reflectors to get ruined.

Second question...What is a good ph monitor/controller to use in a calcium reactor?

1) hanging it up that high should be no issue, but if you want to protect it from any potential splash, then get the glass bottoms.

2) I've got a milwaukee monitor and works well, but if you affort, something like a neptune ac3 would be better as it can do other things besides just monitor your ph... more expensive, but less clutter

the neptune can controll the ph too?
