Not a day after I loose Fishy to whatever is killing my girls I have a heater crash in a different tank. Woke up this morning with one of my 10gals at 58 degrees. The 2 boys are still swimming and active. I have now replaced the heater.
My question is how quickly can I increase the temp back to 80? Should I let the heater do it by itself or manually increase it a couple of degrees too, to at least get it in the green? I'm going to do a 50% water change on that tank today anyway, so I don't know if I should get the temp up a little with that change.
