you can insulate your resivor.... there are these new hydro raft systems (well not that new), that are being used in the desert.. they insulate the resivors...

there are also water chillers...

can you lower the temp of the entire room?

if you are going to scrap the plants, you may as well try to get a fish net and take all the dead matter out of your resivor and then give them a massive does of h202... and even add an airstone....


what's the worst that could happen? they'd die...


sorry about your loss.. root rot sucks!!!!!
