Hard water deposits inside tank walls

    I've noticed a lot of hard water buildup/deposits along the top rim of my tanks, where the water level is, which makes sense, but also in weird streaky patterns inside the tank walls.

    1. Why do I get the deposits inside on the walls? I scrub the inside walls occasionally with a sponge when I clean the tanks, but that's usually to remove the streaky deposits I see.

    2. Will the removal of it with a sponge harm my fish? They all seen fine, but I does cloud the water for a few minutes when I clean it off. Stirs everything up, much like gravel vacuuming does, and then it all settles again.

    You need to clean it off when you removed some water on your next water change. Letting it go back into your tank water is only increasing the calcium in the water.

    That's when I do it. :)

    Anyone have any thoughts on this? :/
