Hi everyone, I'm getting ready to set up my Geo Kalkwasser Reactor on my 40 breeder coral QT tank. The circulation pump (mj600) along with a dosing pump ~ 1ml/min, will be controlled by my Apex.
To calculate the amount of Kalkwasser to dose my aquarium, I used the kalk calculator from Hamza's Reef website: http://www.hamzasreef.com/Contents/Calculators/KalkContribution.php
After several weeks of testing my tank, it appears as though I am dropping about .22 dKH per day. Check one: Does this sound right for a bare bottom tank with about 60 sps frags, no fish, and a 4" T. derasa ?
According to the calculator (assuming I used it correctly :) ) it appears as though I need to dose about 340 ml per day. Does this sound OK? I also did a quick check against Randy's Kalk article, and it seems I'm well below the .25% of tank volume "rule" for keeping the increase in pH below .2 points. Especially considering I'm planning on dosing the 340ml in smaller increments.
Which brings me to my next question; Lights are off at 5pm, so I am planning on spreading the dosing out between 8pm and 8 am. Perhaps about 42 ml every hour. Does this sound OK?
Finally, GEO recommends running the stirring pump 4 times per day, at about 1 minute each round. Should I break the stirring up evenly throughout a 24 hour period, considering I will only actually be dosing at night? If not, what do you recommend?
Lastly, how long should I wait before running the dosing pump assuming that the kalkwasser has just been stirred?
Thanks,
Nathaniel
