can't maintain alkalinity

[fishface]

yup, able to maintain those parameters...but now i'm battling a slight drop in pH. could still be salt. anyhow it's not too bad but it's dropped to 7.9-8ish so i started dripping kalk to see if it'll stabilize that problem.

if it isn't one thing it's gotta be another huh?

What salt brand are you using?
I'm glad you were able to stabilize everything for the most part.

michika, i've been using oceanpure pro until last week but i'm really not happy with it and have since switched to reef crystals. only time will tell how that's gonna be, on a brighter note, the kalk seems to be working wonders at keeping my pH at bay, hopefully it'll bump that up a few points and i'll be laughin'.

[michika]

How about another update?

I'm following along because I suspect a similar problem is on the horizon for myself.

[fishface]

well...until this bucket's gone it'll have to just do. my numbers are in the vicinity of 7.95-8.1ish and i'm no longer dripping kalk as i'm just too lazy . i'm not into chasing numbers either so...i will go back to kent salt as i recall it had good Ca and alk parameters for reef tanks...

I use oceanpure pro & my ph is a steady 8.2. I buffer to 8.3dkh I would like it higher but everthing is happy in my tank, & if left it would take awhile to drop passed 8. My calc is always @ 440ppm as well. I do about a 20g water change each month in a 230g with a 60g sump. I dont use kalk or have a calc reactor, I dont have the need so far but it would be nice just to be able to keep water more stable & add trace elements. Every system is diffrent, diffrent coarls, lighting, even water etc, so in one system one kind of salt works great, but that same salt may not do well in another. I tryed a couple diffrent salts including reef crystals but I had to add calc. Sorry to ramble just my to cents
