PH meters - why sell?

[slcw]

Hello,

i did a search for Ph meters, i realise a number reefers were selling their PH pens, some shortly after purchase.

Why? Too much hassle?

Confused

Some of them have started to use pH monitor or controller.

there are a few bulk orders for pH/ORP controller in another local forum, so its not surprising to see them letting go of thier pH pen.

pH pens are not a hassle to use.

but along the process of tuning your new shiny monsterous Ca Reactor, a monitor can be slightly convienent to use. Or you are using its probe inside the reactor camber to run

Hard to comment on my one.
