Hi folks, sorry for posting with a question straight off but I'm hoping for some opinions. I am in the planning stages for my new 2ft (70L) tank. It's going to be planted, not decided on high tech or not yet... But I need a filter for it. I was looking at the Eheim 2322 Professional filter with built in 150W heater but it has a reported 500lph flow rate. Is that going to be too much ? Should I consider a lower throughput filter with a hydor external heater ?
