help starting dosing

[turbo2oh]

I have a 60g cube that's lightly stocked. I'd like to start dosing though just to get my Alk solid. I'm trying to determine how much Alk/Ca to add per day so I've been measuring my Alk for the past week. It seems like it drops a little over 1dkh per day.

 

Day 1 was right after a water change:

1) 8.1

2) 8

3) 7.8

4) 7.7

5) no measurement

6)  7.4

 

Based on these results and the BRS calculator I should be adding  approx. .1 or .2 fl oz per day to keep it steady.  Can I also assume how much Calcium I should be adding per day based on this Alk usage or should I measure that for a few days and determine dosage based on that?

 

Thanks!

Measure the calcium as well. Some tanks use ALK/CAL in different amounts.

Typical ratios for consumption rates:

 

Fore every 2.8 dKh alkalinity drops, 

calcium is reduced by 18ppm,

and magnesium by 2ppm/

 

Consumption rates shouldn't vary though dosing rates may because of the differences in the way the solutions were prepared (or supplied from the manufacturer). 

 

It looks like you're consuming approx .15 dKh per day. I wouldnt even bother dosing calcium at this point.

Thanks! I’ll start dosing Alk and measure calcium for a week or so just to see if it changes.
