Hi Guys, Please help!
I have just noticed a white chalky substance growing on the live rock and base rock in my newly setup tank. It is a 130 liter tank and has been going now for just 3 weeks. Still in the cycling process. The live rock had lots of purple growth and even a few fan worms growing all over. Suddenly (it appeared within a few hours) we notice a pure white chalky growth/film on the live rock and even on the base rock. The tank is not milky. The temp is 26 degrees and the Ammonia levels were 0.5 after 1 week and are now 0.1 after 3 weeks. The SG is 1.025. The PH is 8.3. Is this chalky substance normal during the cycling process.
What to do?:(
