fish-f -- Maybe I over stated my position. It has been my experience that gph is where most folks short the aquarium. I have a large biological exchange but I think that the amount of water that crosses the media is extremely important. M.

Fish-f -- You are correct about the amount of media vs the gph. You have to start somewhere when it comes to sizing a filter. I speak for myself, but most folks start off with way too little gph and then try to keep adding media to make up for their water flow short fall. I believe the 5x rule is "at least" and is a minimum. I have a 30 gallon with a 350 gph hooked to it and it does a great job. As the gph goes up so does the price and that is where the short fall begins. My next filter is going to be a FX5 on a 124 gallon.

I believe that the Eheim stats on the chart for gph are incorrect. According to their site, Eheim's stats for the Professional 3e (2078) are 1850 l/h, and that converts to 488.7 g/h, according to an online conversion calculator. The Pro 3e has variable flow rate settings, but just comparing that 488.7 g/h to what the chart says, "88-242 g/h", something is amiss.

I have a 75 gallon tank filled to about 70g and this one filter cleans it really well, biologically and solid waste. I have two 4-5" RESs and over 30 fish, plus plants whose leaves keep the filter's intake basket challenged all the time ;). My point being, I doubt the 88-242 g/h is correct in the chart or I'm missing something.

Cool chart thanks!
But my Marineland H.O.T Magnum says up to 55 gallon on the box and the chart says up to 75 gallons? Why is that?

You guys keep talking about the 5x rule... What exactly is that? Haha. 5x the amount of water in the tank per hour?

Filters are rated or recommended for specific aquarium sizes but turtle keepers will require a bit more power. For instance, a 100 gallon fish tank needs a filter rated for 100 gallons but a turtle in a 100 gallon tank should get a filter rated for a 300-500 gallon tank.

The link is currently broken, is there an update page for this information?
I am looking at getting a canister filter, likely a Zoo Med Turtle Clean 511 for my two RES.

A zoo med filter is probably not your best choice. What size tank do you have? And what link is broken?

It doesn't have the Fluval FX5 but other Fluvals are there.

[admin note] As requested, I stickied this page and transferred most of the content to a page on the main site: http://www.redearslider.com/filter_chart.html


I apologize, the petsolutions link. I failed to notice the fact the same info was found on the site.

I have a ~40 gallon long, with about 30 gallons of water. Come spring, I plan on building a larger setup, and would still like some filter that can be effective for whenever I may need to use this tank for temporary uses.
