I do my water change 1/month. 75gal tank. I don't drip my kalk, I use 1 gal of kalk water mixed with RO water in a 5 gal bucket and top off the tank with it. I had a bad experience with drip before. I use 2 Tbsp kalk per gal let it settle overnight and pour the mix in a clean 5 gal bucket, top it off with RO and use it for top off. This bucket last on average 5-6 days.
