ok...thanks everyone....I actually got nervous and went out and purchased another heater today......it's a better heater than the one I got with the tank....and so my plan is to leave both running while I'm away and then I'll just use the new one and save the other for a hospital tank or something.
I have another question though, if you don't mind.....
I decided to do a water change and cleaning today (this way it's close to my departure, but I'm still around for a couple of days, just in case)...and I noticed that my filter seems to be producing a very weak flow.....this has happened before, and I just rinse the sponges and everything was fine.....
So.....as before, I took the filter out and thoroughly rinsed out the sponges (which I did in tank water from the water change). When I replaced the filter, it ran well for a minute and then the water flow totally stopped.
I jiggled it a bit and water flow started again, this time, full force....a few minutes later, it stopped again......
I picked it up and tilted it and the flow came back...and when I put it back in its spot it went off again......
I had to go out to dinner so I left it...now I'm home and it's back on...but who knows how long that will last or how long it's actually been working.....
What's going on?
The filter is a "Fluval 4 Plus"...anyone familiar with that model?
