New filter

[bryon001]

I currently have a 75 gallon tank with a Marineland Magnum H.O.T 250 and an Aqua clear 55/75 running. I am upgrading to a Fluval 306, but still want to keep one of my other filters on as extra filtration. My question is which one of my current filters should I continue to use? Or, should I run all 3? It is a planted cichlid tank with a large (18") pleco

I would run all three at least until you cycle the 306. Your previous filter capacity was actually higher, and I would probably keep the AQ70 running. Great filter, and it and the 306 should give you the 10x hourly turnover that is best practice. Good luck.
