Reddit reviews Eheim AEH2260380 Aquarium Filter for Model 2260-38

This is the filter I managed to pick up for it for 125 bucks. It is WAY bigger than that picture makes it look, and is right about the size of those large 5 gallon paint buckets you get from home depot. I have actually only did a partial water change a single time, and other than that just refill every 3 or 4 weeks based on evaporation. Still have not had a need to clean or replace media in the filter as it is still operating completely smoothly and keeping everything absolutely crystal clear. I think a big part of that is that he is the tanks only inhabitant, and he is very good about eating all of his food within seconds straight from my hand, so he doesn't make much of a mess at all. I do need to skim surface on occasion as oils from meat contacting the water will slowly build up, but since they all float they stay out of the filter as well. Overall probably the easiest tank to keep clean I have ever dealt with, I have only had a single bloom of brown algae, but a little bit of iodine cleared it up within a couple of days. Another big part of the cleanliness is likely the hard rock bottom. If there was sand or gravel that Mr Bitey could reach I am 100% sure he would be making a disaster out of the tank on a daily basis, when I had him in smaller tanks that had a gravel substrate I was having to change water for the whole tank every couple of weeks, and having to outright scrub the gravel substrate clean by hosing it down for half an hour. Definitely avoid loose substrate and it helps SOOO much keeping things clean and awesome.
