I was doing the 2 gallon weekly water changes, and it didnt seem to be keeping up. My Ca was never over 400. It usually peaked at 375. Kh was always around 7. Now Ca is about 450 an Kh is about 8.5 or 9. Dosing seems to be working better for me then just the water changes.

So how large of a tank would you think I would need before dripping Kalk? I would do the 2 jug drip but I think it would be a little difficult to adjust the to drips to where they were dripping at the exact same rate. Those plastic air valve dont seem to be the most precise pieces. Would IV drip regulators work any better?


Thanks,
Mike
