I keep a 40 long on the top of my tank rack to age water to siphon down for topups and I am wondering if there is anything practical I can do with it besides just holding water? I keep an air stone going in it btw.

It just seems like wasted space in a way and looking for ideas to make it more useful than just topups

If it gets enough light, why not use it to grow something you might be able to sell ? I'd suggest Guppy grass. It is almost impossible for stores to get from commercial plant nurseries, as it does not ship well at all. Tends to disintegrate very, very quickly if the water is not moving around it. Grows with next to no attention, though if there are no fish, you'd have to feed it a bit. I've been selling mine to stores for credit when it outgrows the space I have for it.

Guppy grass doesn't need a whack of light either. Mine grows fantastically well in the light from the windows alone. They face more or less south, with an overhang from the balcony above. Can fill my 29G in a very short space of time, compared to most plants. Given more light it just grows faster.

virtually no light, no substrate, just a tank for holding water to siphon down to topup other tanks, not even a heater, just air stone

If you could put even a single tube over it, it would grow guppy grass, which is a sub surface floater that needs no substrate at all, and also no heat. The air stone would be fine for it, just so long as the water is moving some, it's fine.

I change water often enough I don't need topups..

Maybe its time to pull that tank down and put that other fish you want to keep in it


I know I wouldn't be able to let a tank sit more or less empty.
