Don't mean to side wind my own thread. But after I set up my tank and got my gravity fed resivoir to line up and work I'm noticing that I have with lines at the very top of water line in dt
I guessing calcium? I never use to see this because I got my r.o. and salt water from CG. But now my water source is the city of Tustin.
Is this going to cause and issue?
Guessing more maintenance? Is this bad for fish? Now mind you the city water source is going Thu a 4 stage r.o and dual d.i. set up.
Please advise...
