I have a 55 gallon aquarium. I've already cleaned it but it's been 6 months since I've cleaned it. I haven't bought a turtle yet (waiting for Southern Painted Turts to restock, unless you want to tell me a website where I can buy turtles), but I already have most of the stuff on my checklist. 2 filters. A penguin head (don't think I'll need it). Lamps and Uvb/Heat light, glass heater (Jager, gonna buy a protector.I also have another one. Penn Plax. What are your thoughts?), and some decor. My questions. I bought all of this for 180 (an aquarium stand, colored led lights, and more colored lights were included), but the filter and heater are covered in what looks like salt creep. Plus some dried green algae. Will the water become salty if I just leave the filter and heater in the aquarium? I don't want my turts to die because of saltiness. Second, do I need a screen top? My 55 gal has a screen divider and was just wondering if I do. Some people say the screen top absorbs the heat from turtles. I dunno. 3rd, what do you do when you put chlorinated water in? Leave it for a day, then pour some de-chlorinator in? Or can you just put the de-chlorinator in from the start?
