Your welcome. I'm glad I could help.

Another thing I do is tie a piece of string around the top of the plastic bottle and tie it around the outside of the tank somewhere. That way it doesn't float all over and bang into anything when it goes through the current of my powerheads.

Hot tanks...

Turn the lights off. Even with heaters unplugged I've had water temperatures up at 86 plus degrees Fahrenheit.

The fish don't seem to care for the few days of a British summer and my water gradually went down by about 7 degrees. This has a far greater effect with dual (or more) lamps.

Also, as somebody else as said, turn the air up if you can - it increases evaporation and oxygenation.
