Tetratec ex600 for 60l BiOrb Life?
I'm converting a 60 litre BiOrb Life to run an external canister filter. Would a Tetratec ex 600 fit the bill? It's going to be a heavily planted low tech tank with a few nano fish, shrimp etc.
I'm mightily confused about filter turnover rates. The usual "rules" of 5 to 7x suggest a turnover of around 400 l/hr, but in the threads I've read, people keep suggesting filters with a much higher flow rate than the rules suggest. I.e. a 2217 on a 20 Gal, which is double!
