Further to my queery about using the de humidifier water for makeup water, which I wont do (thanks to all), is 2 1/2 gallons of kalkwasser per day to use fur make up water? Because the pH is so high I thought it might be too much.
It probably is too much. Remind us what size system. Odds are it'll be about one gallon a day, dripped overnight when pH is at its lowest.
Hey Marc, My tank is 125 with 25 or so sump. Do you have a DIY for a drip system?
