Review on 🐠 OASE Filtosmart Thermo Indoor Aquatics by Alexis Leonard

I don't know what I'm doing wrong but my filter works great. Quiet, efficient, does not require frequent cleaning: has not been cleaned since purchase 3 months ago. Don't think you can buy ten goldfish, put them in a 10 gallon tank and they will be fine with this filter. 10 liters is enough for a group of guppies and not enough even for a goldfish. I have a fair amount of fish and lots of live plants. Never been happier
