I believe there is some devices on the market which allow you to remove+gravel vac and add water.hi,
Stupid question , can you use the gravel vac when refilling the tank or something else sorry im new to all this.
chriso.
apparently, if your tank is very ell established and you only do a small water change, it wont cause that much harmStrange it may be, but i do a 25% water change on my 5ft(350L) planted tank without dechlorinating the water, i just drop the hose into the other end of the tank to the intake of the filter and fill it back up to the line, i have not had any losses, fish all seem to be happier than they were before.
Smaller tanks require dechlorination, but larger don't in my opinion
Great advice! I never even thought of that!This is great - and I hope lots of beginners read it!
Just a quick point - when you refer to refilling and you mention the "bath" being much faster, what do you mean? If it's that people should use water from a bath tap, I have read that this is not necessarily so great. I'm told that this is because indirectly heated water is stored in a copper tank, and this is not good for fish. Not certain how true this is, but when I was starting out I suffered a fatality everytime I changed the water, and I was using hot water from the tap mixed with cold.
I now use cold mains water mixed with boiling water from the kettle. It means several boiled kettles for the change process, but I've never lost a fish since.
