I personally prefer 10x turnover because I'm a bit obsessed with tank cleanliness and ... My fish do actually like it.. All different types of species . Having that turnover gives me far more room for laziness when I decide to be. My tanks are cycled so I'm not worried about them being "more cycled" ... Just stays visually more clean for longer. While I get busy traveling and leave my tanks alone for a month or two ... While Jaysee (and most the rest of the world lol) would say my tanks are clean and water looks good.. I'd see it differently .. Yet far better then if I went by the old idea of 3x turnover rate. There are more reasons but these are my main ones .

Actually I shoot for 12x turnover in my African cichlid tank and have a powerhead for added current on top of that . They lose their tempers without enough current . All hell breaks loose when the filters are off .. Even just 1 of the 3 being off can cause fights .

I thinks it's a misconception that a lot of tropicals don't like / can't handle that type of filtration/ water current.

Pop I'm not ashamed of any of my practices

You can't have the bio filter only in the substrate unless you only run Powerheads for circulation. If there's filter media the bacteria will be distributed primarily between the two (substrate and filter). What if there's no substrate?

Hello .Jaysee;
What if there is no media in the filter?




Hello Agent_13:
One small question since water flowing through the filter at a nine gallons a minute for a 55 gallon tank would reduce filter’s ability to capture particulate matter how would this increase aquarium’s waters clarity and improve cleanliness.
Let me state I am not questioning your knowledge or excellent fish keeping skills but just trying to understand.

Filtration

Pop,
Can you explain how it does not catch as much particulate waste? If it doesn't then perhaps you are in fact using a canister with no media . And I'll add.. I almost always have more then 1 filter on an aquarium that together are collectively running at this rate . Outputs and intakes all strategically placed . A lot of my filters have ceramic prefilter then increasingly more dense foam then the biomedia, carbon(which really isn't often if ever replaced ) and then something for water polishing. All I have to do is look at my tanks to know the gph is absolutely not impeding my filtration effectiveness ... Quite the opposite .. Then cleaning the filter... When I open the bottom valve(on ones setup like that ) you see what was being taken out of the water column. Then go through the media from where the water flows in to where it flows out.. I see that my biomedia is relatively particle free .. Which means the BB has more contact with the water flowing through.
When I kept my African tank at something like 7x turnover is wasn't as clean as with 3 canisters running 12.5x . Messy messy fish

Now on the absolutely absurd side of things I do have a 6gallon with a betta running at somewhere no less the 25x ... Overkill absolutely lol. I'll admit he doesn't love swimming right in front if the output but otherwise not bothered by it. That tank I can and have neglected for months on end . Stays clean and pretty like a bedside tank should . I'm probably a little more Jaysee-ish with that tank . I'll clean the filter perhaps a couple times a year at best.

A filter with no media is a powerhead. My point about there being no substrate is eliminating variables. If you want to examine the nature of the bacteria colony in the filter, then you must isolate that aspect by disregarding the role substrate plays in the filtration process, since it's more or less a fixed role - the substrate will do what it will do.

Good morning Agent_13 & Jaysee;


Wow what surprise a filter without any media is a power-head I did not know. Will this definition include hob and hot filters?


In truth I have absolutely no desire to know exactly what the bacteria are doing in the filter. My only interest is the Capture of particulate and the efficiency of the capture.


The answers about filtration remains a mystery and when reason is applied Fails to add up for me, I guess I just have to accept that this mystery is part of the holy grail of fish keepers and thus a secret that defeats sound reasoning and logic.


Thank you all for your effort to educate me.

Well, what is a filter? A pump that holds media. Without media it's just a pump circulating water.

I too couldn't care less about hat the bacteria actually are. I'm content to know the job they do and how they act.

We all say that the fish tank is a mini ecosystem, but in reality the filter is it's own mini ecosystem within the tanks ecosystem

I'm confused at what confuses you lol.

What I've gathered from some of your posts it sounds like you think increased gph make particulate capture harder for the filter ? Am I right .. Is this one of the things you're hung up on?

I too go for big filtration - high GPH on a larger tank means multiple filters, and multiple pickup points for the filtration system means better capture of particulates. The strength of the draw from the filter intake is strongest closest to the intake. It drops off considerably as you move away from it. That's another benefit of the higher GPH - the current carries the waste towards the intakes. My tanks filtration systems are designed to create a circular flow within the tank. One filters outflow pushes water (and waste) towards the other filters intake and vice versa. It's synergy.

Is your concern that the higher GPH will push the waste THROUGH the filter media back into the tank?
