Would this setup work with no filter and heater?
I always like to hear from many sources before doing something. It was suggested by L.R.Bretz's Aquatics in a video.
I was thinking of setting up a tank with no filter, no heater. It will have basic substrate, light, a lot of fast growng plants, guppies, cory cats, and of course other stuff like wood and rocks. I was wondering if this would work. I will still be doing water changes ever 2-3 weeks or so. Depending on the tank of course. I would use a heater if my room gets too cold but my room doesn't and should be fine for guppies and cory cats.
From my knowledge of aquariums, it seemed it would work but I just want to be sure. He says that obviously the plants would be the filter and don't have too much bioload of fish. To move the water around that is where the guppies come into play constantly swimming. I am no expert and wondering if this would work. Thanks.
