Bro me just do aged water top up if water level drop and WC bia weekly 10% to max 20% to suck up CRS waste. As long temp and PH is gd that is most important to me.

for me 20% a week , using aged water wld be better, but water direct from tap with anti-chlorine added also can, but not large volumes

ok thanks for all the advise

I normall don't change water, just top up as frequently as possible.

Maybe once in a long while, I siphon out 10% of water and top it up again.

Becareful of large water change. LAtely heard that water from tap cused many deaths of aro and other fish. Half my population of cardinals died after water change. !!

I guess it would depend on the bioload of ur tank.

For me, I change 50pecent of water weekly for a high bioload tank which is around 100pcs of shrimp inside a 2ft tank. This amount of change can helped to reduce nitrate in tank.

Im not using any aged water, just direct tap water but have to make sure water conditoner used is able to get rid of water chloromaine.
