I been adding Kent Kalkwasser 24/7 for 2 weeks. I am using a DIY dripper to dose it. I am using 2 teaspoons per gallon. I started with that much because I have a lot of CO2 in my basement. Recently I have noticed that holes have been appearing in all of my Fiji live rock. I want to stop this immediately. It's as if the live rock is disintegrating. Things that were done differently recently were adding a fan (over the sump), kalk, a sponge (in the aquarium for future QT), increasing the time the actinics were on from 12 to 14 hours and daylight from 8 to 10 hours. I have stopped dripping kalk today.
I did have high alkalinity (5.5 meq/L) couple days ago. Yesterday I did a 26 gallon waterchange. Today the alkalinity was 4.0 meq/L Before I notice the holes, I was happy with the results of adding kalk. I was able to maintain my pH around 8.0 to 8.2 and coraline was spreading on my rocks.
I stack 2 Kent buckets behind my aquarium. On top of that I put my 5 gallon jug of kalk. The last batch of kalk was left for about 2 hours to stand still after mixing. Then I started dripping it. I was in a rush that day. I normally have another jug on the floor that sits overnight with kalk. When the top jug becomes empty, I swap it with the one on the floor. I don't think that moving the jug from the floor to top of the Kent bucket would disturb the sediment of the bottom.
To get the kalk dripping I blow in one of the tube in the lid. The valve on the end of return line is loose. So the kalk pours in but I quickly tighten the valve to a slow drip. The pH monitor reads an increase of .08. But with in seconds goes down to an increase of .01 to .02. It takes a couple of seconds for it to disperse. My pH never swings more than .2 in 24 hrs.
What do you think is creating these holes in my live rock? My tank is full of pods, chaeto is growing well and coraline is spreading. All signs of a healthy aquarium.
