I figured it was worth a punt. Plus I'm not very fussy.
They did try and sell me nicer/more expensive stuff with the kit but I figured the first batch was highly likely to be shite regardless.

The stuff has been going since Sunday and is hovering around 18 degrees. Which is a little low. If it tails off I might need an aquarium heater.
