I thought this might be interesting and help others deciding on what tanks to try. :)
I'm using a Protank 2 and so far it's my favourite but being new to the scene I've not tried many.
I've also used the iClear16 & iClear30 but won't get any more, definitely don't like the top fed setup.
I also tried and liked the Mini Protank 2 & MT3 but not as much as the Protank 2.
What's your favourite and what have you tried?
