Digital Water testing meters

[Anonymous]

What are you guys using and what do you recommend?

ph/alk/TDS/etc...

Maybe there is a kit that has a group of digital testers?

there is no all-in-one digital reef meter that tells all. you have to buy them a la carte.

I have a Hanna "pHep5" handheld meter I use for the occasional pH check on the main tank (it also gives temp which is a good confirmation on the thermometer already in the sump).

I also have a Hanna "Primo" handheld TDS meter I use to check product water from the RO/DI. I've got a dual inline TDS on the RO/DI (don't remember the brand off the top of my head) as well to periodically make sure the membrane rejection rate is OK.

Alk I generally check with a Salifert kit.
