Hey,
I've been searching through aquariacentral,(as some of you know) and I can't seem to find much on water changes. I know they have to be done, but when? and how much water should be removed? Any other tips will be great!

Thanks!
PAint.
 
water changes depend on lot of things... for me its time involved I have 3 tanks so I do my water changes once a week on saturday for the 55 and some times every day on my smaller tanks(i know its not necessary the gunk bugs me). my 55g gets 10 gallons+what ever evaporated, the 10g amount comes from how much water is sucked out to get my gravel clean. for my smaller tanks its just as much as it takes to remove the gunk from the bottom of the tank.

another this is how your stocked... if you keep a tank full of goldfish or other know poop machines you may want to change your water more frequently...
 
I have a set mark where I drain to on my 20g tank. It's roughly 25%. I do WC once a week unless I've added a fish or am dealing with disease. Pretty much the same for my 10g tank.
 
Once a week for my 55g tank. For my planted 10g only if there is something wrong with the water because the plants take most of the bad stuff out.
 
The easiest way to do it and explain it:
Get an API liquid test tub kit. Test your water every few days at 1st (after the tank is cycled) and when the nitrates get to 20 ppm, do a 50% water change. After a few wks you won't have to test so often because you'll know about how long you can go before the water needs changed. It all depends on how many fish are in the tank, how much you feed, etc, etc.
 
:iagree: 50%,once a week,is a good routine to have no matter the stocking, or whether or not you have plants.Fresh,clean water is always good for the fish and the plants.
 
It depends on the tank. My planted tank gets a 50% weekly WC but I dose fertilizers. My 125 African tank gets a 20% weekly just to keep up, but they could probably get by with less. It really depends on the tank. What setup are you running?
 
Ask the residents of the tank- they like minimal changes. WC involving lower percentage of replenishment done more frequently is better than WCs with higher percentage done farther apart.
