Being mildly worried about the cost of running 6 tanks around my house, I'm running an experiment on my Community tank.
What i'm doing is comparing power usage for 1 weeks power with different insulation each week for the next 4 weeks.
Week 1: No insulation
Week 2: 12mm Polystyrene on 3 sides, not inc top
Week 3: 12mm polystyrene on 3 sides, inc top around lights
Week 4: 12mm all around except front during the day / evening.
The Test Tank
130L community tank, 5 Dwarf Gourami, 5 Striata Loaches. 5 Tiger Barbs, 4 GBA (young), 1 SAE, 3 BN, 1 Plec, 1 Siamese fighter
Filter: Fluval 205, cleaned weekly for duration of test.
Heater: Jager 150w, 25 Degree temp
Lights: Two 15 watt tubes, on a timer for 8 hours a day.
I'll post a pic later this week of this tank, and a new photo of tank with each insulation setup.
Any tips or ideas let me know and i'll try and include them
