I searched but couldn't find a definitive answer on this.

I have a 2.5 gallon filtered tank with a betta and a mystery snail. I understand smaller tanks need more frequent water changes. Will 25% water changes every other day and a gravel cleaning once a week be enough? Too much?

Thanks.

dont no much about small tanks but when you clen gravel just do half on week and half the other because you dont want to agitate bacteria

Vinht, what you have suggested should work just fine.

Hi vinht
Assuming that the tank is cycled, and the readings for Ammonia and Nitrites are 0.
Nitrate reading will govern your water change requirements.
I dont know what level of Nitrates are ok for betta's, but lets say 20 for the point of this exercise.
If you are doing a 15% water change twice a week, and you find that when you test the water ( once a week before water change ).If your Nitrae levels remain under 20, then you know you need to do 15% water changes twice a week.
If you find that your Nitrate levels are slowly going up, then increase the water changes to 20% and see how that goes.
hope this helps

Make sense. Once I'm done medicating Harold and can get a test kit I'll give that a try.

Thanks!
