If one listened to all the well-meaning but ill-informed commentators on social media about aquarium maintenance one would be doing the following:
- Do 50% water changes every week
- Thorough gravel vacuuming every week
- Mechanical media cleaning once weekly
- Bleach brown algae off the ornaments every two weeks
- Filter media cleaning and/or replacement once a month
- Clean the algae off all sides of the aquarium weekly
- Feed the fish three times a day
This amount of maintenance is NOT needed and is such a pain in the butt that anyone doing it will leave the hobby in very short order.

In truth, with most aquariums, for maintenance, one can simply do:
- Do a 50% water change every two months
- Do NO gravel vacuuming
- Clean the mechanical media in the filter once a week
- Just let the brown algae do its thing
- Partially clean the filter media once every six months
- Clean the algae off the front and side glass once a week
- Feed the fish once a day
Probably 95% of all aquariums in the hobby are just fine with this regimen.

Hi Dave, I have some stupid questions:
Can a 10 gallon tank EVER be balanced – or is it too small?
When you say “Clean the mechanical media in the filter once a week” ……I have Poret foam in a Tidal 35…….am I wringing it out?……..I never touch it.
I have gravel substrate, UGF, Tidal 35 and a homemade K1 micro moving bed.
Right now I’m running a UV sterilizer – there is no fish in the tank. When I have a Betta it is fed a small amount of high protein food once a day (with a day off). The tank is about a year old.
The water is crystal clear – but I still feel I am doing something wrong………or is 10 gallons just too small?
Thanks as ever,
Eve Taylor
