Our water is basically liquid rock and is high in calcium/lime. In the tank is Lava Rock, Driftwood, Live Plants, and Sand. Over the past few days I have noticed some white deposits forming on the glass. After scrubbing them off with an algae scraper, they were pretty much gone. There were a few patches on the back glass left, but not much. One morning when the lights kicked on I saw this:
It was like it happened overnight. The timers are set for 5 hours on, 1 hour off, and 5 hours on. Water changes are done weekly at 35%. The only thing that is in this particular tank that is not in any of the others is the live plants. I am not dosing with ferts. The tank does not receive even the slightest bit of direct or indirect sunlight.
I thought about scrapping it all off with a razor, but I don't think the fish would appreciate white chunks in the tank. The substance is very hard and bumpy. It's not a smooth surface. Tomorrow I am going to do a massive water change (about 60%) and scrape the substance off into a container so it doesn't get into the water. But that is just a temporary fix. I want to get to the bottom of what is causing this buildup so I don't have to do this every few weeks.
Can anyone give some insight as to what is going on?
BTW- It's not a reflection at the top of the first pic. It really is a big sheet of the white stuff.
