There's no substrate mostly because of space. Substrate is for beneficial bacteria to grow, the screen have enough surface area for that. Also to keep the waste from floating all over the place (screen and plants also help with that). Kind of like Eco-Spheres, except I can open the top and change water every week.
No I'm not dosing. I could do DIY CO2, but I'm afraid of the bottles exploding and getting the contents all over the place. I like keeping things cheap. Might try some Excel to speed the growth, for my other tanks as well.
1-1.5 gallon is full of Vals with 1 inch substrate. Cherry shrimps, guppy fries, MTS snails.
3 gallon is also a grow out thank for guppy fry 1/4 inch substrate, CRS, and MTS. Some Vals, Java Moss, a kind of stem plants that came with CRS, pelia (or some other jelly like foreground plant came with CRS) and duckweed (came with CRS).
5 gallon guppy tank with Java moss, vals, wisteria. 1 inch substrate.
10 gallon outdoor cold water tank (cold water 'cus it's winter) HOT water during summer. Have Red Rosy Minnows and gold fish. Hope they don't boil like my guppies and shrimps did this past summer. Only took 1 hot day during summer and they all boiled (if it wasn't for that 1 SUPER HOT day, they would have made it through the summer), but probably die during winter anyway. Hopefully, this shadier spot won't be as hot and the Red Rosies can tolerate warmer water.
All my tanks are low tech with no filter or heater.
I do plan on putting DIY CO2 (just to make the plants grow fast) in the 10 gallon though. Since it' outdoors and I won't have to worry about the bottle exploding sugary alcohol goodness all over the place.
