Does spent calcium reactor media cause alk drop?

[Matt Rogers]

I thought I recall reading this in the instructions...

My calium reactor media is due to be replaced... lately I noticed my alk and pH have been dropping...

is that an indication that the media really does need to be replaced?

[Jason McKenzie]

No. I've never read that. are you using A.R.M? My media needs replacing when it's gone or a paste at the bottom of the chamber.

That's odd it would cause a drop in Alk and PH how's the CA?

What is the C02 output, Has it changed?

I use the big stuff - Gen X.

I haven't checked everything, but what I noticed last time is that when I first set it up it stabilized my alk and calcium. Lately they have been dropping back to pre-reactor levels. I assumed it was because 3 months of passed and I thought I should replace the media. Perhaps it just needs adjusting? I have a lot of media left.

How often are you changing your media?

[Jason McKenzie]

Oh maybe every 10 months or so. Do you have a lot of growth. Maybe your corals are just using a whole lot more

Ha. I doubt it. Especially after my recent crash. I'll do some homework and get back to ya after I do some tests.
