Remove the piping and plug the hole if it bothers you. You could just silicone a glass patch over the hole and then put the piping back if you want it later.
I don't think 83 times would be too much if you can distribute it well. The problem is that you probably can't, not easily anyway. You'll end up with a single strong jet where you want a lot of diffuse flow everywhere.
I think it's probably more accurate to say they're almost always wrong. Though, some jagers you can calibrate, they've got a little stub once the the tank is at temp so you can adjust the guage on the side without changing the setting.
IIRC they've been in the mid 10s range for as long as I can remember here in NZ. Still not very expensive and the price of the fish is nothing in the cost of keeping it.
There are some big 40 watt energy saver bulbs around, I bought one and it seems to be working pretty well.
Wait, didn't realize you had such a small tank. The smaller ones will be heaps.
Just a matter of time until it sticks on again. Every time it switches on there's a miniature arc welder trying to weld the contacts together and that has proven it's sticking already.
Just yank it out and get a new one tomorrow. In a nice warm temperature controlled(I assume) workplace they'll be fine for a day or two, it won't get that cold.
Use an audio editor to combine them into a single long mp3?
And are you sure it isn't whatever you're using to play it adding a small pause as it loads the next MP3?
