I'm going to vote "yes" on that one. My mantis seems especially well suited to hunting crabs and other shrimp.

I don't dose related to evaporation. Evaporation is compensated by a separate system that delivers RO/DI water. In my case, evaporation is not related to Kalk addition. Ph has not been a problem. Generally, regular water changes do not cause any significant movement in these parameters...

Unfortunately, I don't have a calcium reactor and don't really have room to add one at this time. This is the root of the problem. If I dose Kalk to stabilize Alk, my Ca levels climb too high. If I dose Kalk just enough to maintain Ca, my Alk level falls steadily.

Thanks...maybe I'll shoot for a lower, balanced level. Maybe there is more stability at levels lower than 410/2.8 I've been able to stabilize the Alk by dosing Seachem Reef Builder 1 tsp/l at 12ml/hr. Ca drops much, much more slowly and I'll just do weekly additions of Ca to bring it back...

My tank uses Alk much more quickly that it uses Ca. If I achieve a balanced state (about 410 Ca, and 2.8 Alk), over 3-4 days, the Ca will fall slowly to 400, while the Alk will fall to 2.4. So I have two questions: 1) What might be causing my tank to use Ca/Alk in an unbalanced way? Is it...

I may have experienced the same thing using Kalk in my 40 gallon. I thought I was doing just fine, and seemed to have to add Ca periodically to maintain balance. Then....quite suddenly, I began to get a lot of abiotic Ca formation. At that point, my Alk became very low and I've had to add a...

I'm willing to spend some money to solve a problem. I've been using kalk to try to control my Ca/Alk and I live by your rules. (thanks btw!) I can control the strength of my Kalk accurately enough, but I can't control the AMOUNT accurately enough. Right now, I drip the Kalk 24/7, but my...
