What size fluval internal filter should i get???

[daniel]

There are 4 different fluval internal filters, which one would be best for a 55gallon long, so that there is not to much current. I have always heard Jennifer say go down one size from the size it recommends. It recommends the fluval 4, I know thats or probably to big. So should I get the fluval 3 or the fluval 2. The tank will be probably half full and be used for Cynops ensicauda or Mesotriton alpestris. Which ever I can raise more of. Thanks for the eggs Jennifer!

I use the Fluval 2 on all my 40-55 gallon tanks. The flow is good, but not too much. The Fluval 1 is almost worthless, but the 2 is very good and pretty reliable.
