water change

[jaime007]

How often is best to do a 10% water change in a 15G?

 

[fruity]

I have a 12gallon tank and do 20% every 2 weeks.

But, I have livebearers and they are mucky little monsters.

Once a week - also a gravel clean.

Yes, once a week, of around 25-30% would be good for the fishes... Gravel vac is also very helpful...

I have a 15 gallon tank, and I do a 20% water change every Sunday, which includes a gravle cleaning. For optimal tank health, do it as often as you can.

I saw the gravel Vacume the otherday in action... It looks real easy but powerful, wouldnt it take your plants out of the gravel?

Well, you shouldn't put the plants in the tube...

As long as you can move the tube around the tank without disturbing various objects including plants, you are ok... They look strong but they are not that strong...
