i run them and they do an alright job
better than no skimmer at all
putting a good air pump and wooden airstone on has boosted thei amount of skimate it produces threefold
though the second hand, hang on back one we got on trademe is probably better
pen is 10 metres long, 2 metres wide 2.2 high
chicken mesh floor with weed mat over that and deep sand or potting mix on that
frame is 50 x 50 mm tanalised
mesh 1/2 inch square galvanised
clearlite plastic panel on roof and back
you could use a greenhouse and mesh the inside to stop escapes if glass or plastic is broken
1/2" mesh
plastic sides roll up on sunny days, zip together as well
waterdragons the best climbers, though beardies can get to top of mesh and get down again
100 degrees for 2 to 3 mins then dunk in cold water:D
seriously though get a chiller if you want to keep over summer
5 will probably fight like has been said
