Chago09;2462348; said:this is very true and makes for a good arguement. Although really if you have a tub which your filling already. Just fill the tub, through a air stone or a hob filter for a few hours. I guarantee you the chlorine level will be sooooo low.
Honestly I have kept every CA cichlid that exists and have honestly took my python and filled directly from my tap. I would just make sure the temperature was as close as I could get it. Once filled I would add dechlor like 15-20 minutes later. What sense does that make??? when chlorine was at its highest point(first entering the tank) it was flowing through the system with no ill effects at all. Actually right after my WC is when my fish seem to be the healthiest and colourful. Its like they get a breathe of fresh air.
K now I may be only speaking for myself, I'm in Ontario Canada and perhaps some of you have toxic water and your municipalities add like 50/50 mix of water and chlorine. I don't know. Although my tap water is not of the best quality. I'm in the water business so I know how my city water is. I only drink water through a Reverse Osmosis system. Although in my house I run a softner and my tanks get that water directly. Period. So I may be crazy although I have an Oscar that is 9 years old and 13". I have midas, texas, and butti that are around 5-6 years old. I have a 2 year old breeding pair of jags. I have also raised pretty close to 10 billion FW discus LOL not quite that many but you get the idea.
My SW predator tank gets tap water with salt added of course. Only my reef tank gets RO water, which is not because of chlorine although corals can't have any TDS(dissolved metals) so a RO membrane is required.
I dont fill a tub with water first. I add Prime first then I add water to the tank directly from the tap. I also keep on the slotted gravel thing of the end of the python to help aerate the water and evaporate some of the chlorine. I guess its just peace of mind for me. Another reason I add prime is in case my water has chloramine.
