Hi guys,Im after replacing my tetratec filter for an eheim filter but dont know which 1 to go for.Theirs so many varieties.The first thing though it needs to fit into the tetratec space if its any bigger im not going to be able to fit it in.The space available is 19cmL x 19cmw height should be fine upto 50cm.Im still going to keep the rena xp3 running.The tank carries 90 gallons.Any ideas whats best?

pro 2's are great...probably a 2028 for that size tank, but check....

pro3 is supposed to be superb, but probably too big for you

Thanks mike i'll look into it.

Checked dimensions on the pro 3 but its too big.Got my eye on an Eheim 2128 Thermo cannister filter.Checking and comparing prices at the moment.
