Frequent water changes okay?

[aquamist666]

Is it okay if I perform 50% water changes on my 20 gallon long tanks every 2-3 days? I have goldfish in them. I was originally told to only do water changes once a month.

Sure. Fresh clean water and lots of it is probably the best friend that any fish that lives in a box can have.

I agree and once a month is definitely not enough for goldfish. Especially in a 20g tank. They are messy little buggers!

Depending on the species, they'd need a significantly larger tank too right

I would be very skeptical about any other advice you may have received from whoever told you that.

I have a 240 g system that gets 50 gallons of fresh water daily. I drain out 25g on my trees in a few minutes, morning and night. I trickle the water back in from my filter system slowly, until it refills.

So I don’t often change more than 10% at a time, but it happens twice a day.

This keeps the water more consistant than just draining 50% and quickly refilling, once a week.
