Seen some good info on other peoples thread and I dont want to go with a sump, I rather go with a good canister. Im in between a FX5 and Eheim Pro 3 2075. Im also building a 2000g pond in my back yard and was thinking of getting the filter below its rated for 4500g. Might be a stupid ? but this cost the same as the fx5 and eheim lol why not put that on my 150g.. Just seemed weird that its rated for so many more gallons but yet the same price.
