Hiding heater and pump in planted pico tank
After seeing clean nice planted 1 gal picos, wanted to try it myself, missing obvious points: they had no heater and no source of water movement.
Now I have plants in 18x6x7 in. rimmed rectangular tank, 25W adjustable Theo heather and smallest Tom Dive Clean Mini Internal Filter, 48 gph.
Placing them to make water move around heater is an eyesore, and I don't see the way how to position them to make them less noticeable, especially heater. Tom DC filter, with filtert removed, takes minimal place and keeps flow low enough not to disturb soil (SeaChem hummus aquarium substrate, 2-3mm granules with silt, even rinsed).
Mini heathers with no shut-off overheat tanks or heat them not enough in the winter. I don't plan DIY route with thermostated bottom heating. Air pump for moving water is also out of question, too loud for this room.
As nano reefer, I have other small pumps and heathers, HOB AquaClear (prefer not to use it for this, too much flow, and DIY impeller modifications I would like not to do).
1 gal betta cube for a pico reef was simpler: bare bottom allows 20x flow problem-free and there was no need to hide Theo heather, it looks nice with glass walls and bare bottom.
Now I can't wrap my mind around how to keep flow without disturbing substrate, and keep temperature more or less even. Any ideas?
Tanks I can use for this:
6x6x6 in. rimless betta cube (less than 1 gal),
18x6x7 in. long betta tank (2.3 gal),
and, as a last resort (too big for intended place) long 4 gal Aqua One Reflex 15 Aquarium Kit, with hidden filter and pump.
