Super-heating Tank to Get Rid of Baddies?

[Beverly]

I have recently set up a 72 gal to house captive bred seahorses. I was able to catch the red-eyed bad crab, but have not been able to catch the other furry light coloured ones. Plus, last night while flashlighting the tank, I noticed scores of 1/8" to 1/4" white worms all over the glass. Yikes, not only were they on the glass, but swam about as well I have no idea what these worms are, but they look like very small bristleworms, though I have NEVER heard of BWs that swim

I'm wondering if anyone has ever tried raising temps to extreme levels to get rid of unwanted hitchhikers? My heaters go up to 93 F. I would remove all the good critters from the 72 gal, which only happen to be snails at the moment, and super-heat the tank to 93 F for a 2-3 days.

Anybody ever do this? Will doing so kill the nitrifying and denitrifying bacteria, do you think? And more importantly, will it kill the BWs, crabs I haven't been able to catch, the strange worms, and aptaisia?

I realize the tank will probably have to be recycled due to the die-off, but that's not a problem, considering the benefits of having a pest-free environment for the seahorses when they arrive.

Any input on this proposed experiment would be greatly appreciated

TIA
