Its been 6 weeks since I installed my ATCF400 and still keeps water in mint conditions, I only perform regular water changes and do one shiphoning every week and that's it, filter is working as a clock, i dont think im gonna service it until at least 4 more weeks have elapsed.
I recieved the filter in mint conditions with all its stuff, nothing was missing.
I had no problems to prime it, because I filled the filter 3/4 then I put the lid on it secured it and just needed one push and it immidiatly primed!.
Outflow seems pretty strong , I dont think this filter loses much outflow power once filled with media, it can easily be pumping close to the outflow they say it delivers.
I have been thinking about buying another canister as backup just in case, you know, but as I have read so many good reviews on this one and now I have experienced myself this thing works fairly well I decided to order one more but now under the Sunsun brand, it is the same product only cheaper that the units sold under aquatop brand. lol! in that way when time to service comes I will install the other one completely prepared and just remove the one to be serviced and thats it. Of course I will use some of the mature media inside the one that has been running, it will make the cleaning process much easier and the filters life will be longer as with each changing I will take my time to perfeclty clean the removed unit up and grease it up with food grade silicone grease.
Cheers.
