I was woundering if you guys mark your tank where you want your water line and if you do where do you put it and what do you use to make it. also can you use tropical fish food to feed your tank for the cycle
I've scored a mark in my sump at the normal water level for my system.
Fish food is fine for cycling. Do you have any live rock or sand for an initial bacteria source?
I just use the natural line provided by the lower part of the upper border of the tank. I have about a 1" wood border on the upper, outside edge of my tank.
I use a dry erase marker to mark the water level on my sump. 1 gallon represents approximately a 1.375" change. That way I can determine my evaporation rate.
I also use a dry erase marker on my tank glass to circle things I want to watch. Then, once I figure out what it is, I just rub it off.
