8:45 AM. The whole family is still asleep, but I've been up since 5:33 (trouble with getting older - you can't sleep in) So far I calibrated a new pH probe and tested my tank water at about 7:30 AM - pH 8.3 then cleaned the basement frag tank and the skimmer. I also retested the alkalinity since yesterdays reading was so low, and I added 1 L of B-Ionic as a result. Today's reading was 8.5 dKH
Cleaning the frag tank is a big chore because I'm still getting a large amount of cyanobacteria in that tank. Not sure why, but it seems to collect some type of spiky detritus. I have no idea what the stuff is, but the tank has a bare bottom with 2 tunzes blowing on it continuously and it still builds up a layer of hair algae with red slime on the outside. Fortunately I keep the tank almost empty so it's relatively easy to clean. At the moment it's slightly more difficult than normal because I am keeping my buddies corals and fish in there until he gets his new tank up an running.
