I've added some livestock to the 80 now so I need to start tracking parameters. It appears my alk is dropping 0.5dkh every night. I raised the alk from 7.0 to 8.0 two days ago and when I retested yesterday the alk was 7.5dkh.
I found one of Randy's old articles on kalk dosing- I used kalk and a calcium reactor on an old system. I currently use kalk dosing on my 25 gallon
http://www.reefkeeping.com/issues/2005-01/rhf/. It's super easy to use, just not great for high demand systems. It's perfect for what I want!
Notes from it; 4. Delivering a small amount of limewater all at once. Adding 1.25% of the aquarium’s volume (1.25 gallons of limewater per 100 gallons of aquarium water) as saturated limewater all at once raises the
pH by 0.6 to 0.7 pH units. Such an increase is clearly too large. Adding a smaller portion all at once can, however, be acceptable. Adding, for example, 0.25% of the aquarium volume (0.25 gallons or 1 L of limewater per 100 gallons of aquarium water) will raise the pH by only 0.1 to 0.2 pH units. Unless the pH is high (>8.4) before the addition, that amount is likely acceptable.
NOTE- 1324ml is 0.35 gallons, that is 0.43% of my aquarium volume. I cannot bolus all 1324ml or it will raise pH to much potentially?
Using the
https://www.hamzasreef.com/Contents/Calculators/KalkContribution.php calculator it appears I need to use 1324ml of kalk per day to make up 0.54dkh per day. This means I can dose 55.2ml hourly or 27.6ml every 30 minutes.
