Okay. So. This isn't really betta-related but this was the best place I could put this.
Alrighty. So where my parents live there's super hard water. It's well water. I did just upgrade their ten year old filter with a horrid filter within that's nearly as old, and so now I'm focusing on their tank. The tank has a leak, to put it simply, on one side of it. The sealing on it is coming apart, off, dissolving, whatever. Water's getting out regardless. Now, it's not god-awful terrible (yet), so there isn't much worry, but I want to know how much longer it should go on before we can reseal it or how we should do the resealing. It's not gushing water, just seeping really. The fish seem relatively happy and healthy so far, if a bit stressed from the new filter, and mom is planning on upgrading at some point to a larger tank, but this one is still pretty usable, it's just the seeping on the one side.
And I do apologize if this is scatter-brained. Watching Supernatural and glancing at the tank at the same time, lol.
