I was wondering if I could use some kind of heat mat to bring my 15 Liter Pico reef to a set temp with an Inkbird temp controller. I would buy a Thermo Canister Filter but OASE is from the UK and it's like $100 delivery plus the $180 for the 100w OASE Thermo Canister. And I still think 100w might be too much for my 15L Pico, so I've been thinking how could I hide the equipment and a heat mat sounds like the right idea. So the plan is to get an Inkbird Aquarium heater controller, A heat mat to go under the Pico reef tank in contact with the glass, a canister filter with adjustable flow with an inbuilt UV light. And that should cover the Heating/Flow side of things.
