I think that I will get myself a furnace for my fish soon or they are going to die. The weather is really cooling off rapidly now & will get colder from here on out. It gets super frigid around here during the Winter season & the rapidly adjusting temperatures get to be well below zero degrees for most of the season. It’s 1 of those things that typically happens, however it typically seems to sneak up on me & then surprise me. Whenever the local weather starts cooling off, I get really worried about my fish because I see them so often, but during the Springtime & the summer, I spend a lot of time out in the garden & some of my fish will even come up & eat out of my hand whenever I deliver them a little fish food. I was thinking about getting a furnace for them, however after that both of us just forget all about it & now the weather is already starting to cool off. I was looking online for odd furnaces for ponds, but I can’t really decide which 1 I want to have. I wish that I had a professional outdoor landscaping specialist to talk to you, however the shop that was in our area closed down last year & now I am at a loss. Yesterday I thought about calling the local Heating, Ventilation & A/C supplier to see if they had any suggestions for me. I do not believe they are the right people to call though. They really do not think anything about furnaces for a koi pond, however who knows, however maybe they do!
