so when you mix up the kalk once a week do you have to have it in an airtight container or something? i dose with an aqualifter right now but i can only dose the alk and dose calcium by hand.
I mix it in an airtight container, but it works out just fine having a vented container for dosing. Once it gets a thin shell on top, there is almost no reaction afterward anyway, so its good for a long, long time--much more than one week. I know some folks who mix a garbage can's worth and it sits for over a month--still good after all that time with little degradation. I think Dr. Holmes-Farley had done a similar study on it. Edit: yep, he did. Here's the link:

I don't really understand the second part. Are you dosing kalk or 2 part?
Edit: On a different note, my silly clownfish have begun to attempt to host the new Penicillus I added. It's in a high flow area, so watching them struggle to stay around it is quite amusing. The only catch is that they do it at night, not during the day. They are fairly active during the day, being out and about throughout the tank (not that there's that much room either way, but still).
I've also been observing a lot of other fauna in the tank. The various 'pod populations are exploding. I see hundreds of munnid isopods, gammaridean amphipods (very large ones, at that), and I'm starting to see a good number of harpacticoid copepods, as well. The heavy phytoplankton/rotifer feedings seems to be paying off in that regard. Everything seems to be booming, which granted, is typical of newer tanks, but I plan to keep it that way with this tank. More updates to follow.
