I am waiting for a plumber to come to see if he can even fix this issue, but in the meantime here is the question. The tap water I use to do water changes is very hard to adjust colder recently. It may be a problem with the valve but it also may be because it is darn hot outside and this is the norm for the summer months (new to this area).
Problem is the min temp I can get out of there is almost 84 degrees. Which means when I do water changes on my tanks (set at 76, 77 and 78), even at a 30% the water temp inevitably shoots up to 80 after mix. The first time I panicked and dropped some ice cubes in there, and now each water change is stressful (for me).
Fish involved, not tank specific, are Zebra Danios (who really don't seem to care one way or another), neon tetra, ember tetra, honey gourami, khuli loachs (they hate it), hillstream loach, harlequin rasbora, dwarf blue gourami, von rio tetra, a pair of apisto c and a dwarf snowball pleco named Frank. I also have shrimp in there (cardina).
Has anyone had this type of issue before? Do I need to worry? I honestly wonder if in winter I am going to be doing the opposite and worrying that the water change is too cold lol! However, I think I may prefer this scenario to what I have now.
Thanks for your help!
