Water was freezing at the jets today so couldn't work.

I've gone out and bought 2 300w aquarium heaters which I'm going to fit shortly.

Anyone got any advice for me ?

I've got a 400L upright and am planning to drop one in the lid and another on the other side by making a hole in the top

i bought some monday for my 400ltr tank.
just plug in and drop em in.....take a good 12 hours but you will be able to work.
today the water in my tank was 28degrees at the brush 18degrees.
 i recommend just filling upto 300ltrs
