Just an update...
I finally got some Turbo Calcium and added it to my main tank to bump my Ca
up a few more points. (Dissolved it in about a cup of tank water, outside of the tank, and slowly added it over about five minutes.) My tank went from 400ppm in the morning (when I added the TurboCa) to 420 in the evening - right where I wanted it. I've also added the TurboCa to my PWC
water that I have premade up and got that up to 400-420 ppm
. My alkalinity is staying about 8-9 dkH
and my pH is at 8.3 with my SG
I'd restarted doing the two-part Ca
additive at the recommended dosage, but stopped as it seemed like my alkalinity was starting to creep up on me. After 3 days of dosing, it was about 10-11dkH. Now that I've got my Ca
levels where I want them, I'm going to restart the dosing but only with half the recommended amount and see how that balances out.
A couple things I've noticed...
* Using just the Ca
part of a two-part additive to increase your Ca
seems to have quite a lag time before you can measure any increase in Ca
. And then when you stop dosing, it still creeps up on you a little more. When I used the TurboCalcium... bang - it raised it just like that. (Maybe that's why it's called turbo?)
* I was starting to wonder if my Mg
levels of 1140 were causing me problems getting my Ca
levels to increase. After seeing the results of the TurboCa, I can see that's not an issue.
* If you're doing any dosing for Ca
- even with a "no-brainer" two-part system, get and use a Ca
test kit. The Alkalinity part of it can really get skewed if you're not adding the correct amount. It's nothing that a few water changes won't fix, but in my opinion it's better to know where you're going than finding out after the fact you've got a problem.
