What kind of a turn over rate do you like?

This is something either you overlooked in your threadstalking haste or just are unable to comprehend.
But just for you tcarswell I'll explain it. OK 20 to 23 times turn over on a 240g tank would be 4800 to 5520 gph(this mean gallons per hour). The aquaclear110 HOB(that's hang on back) filter is rated at 500 gph(remember gallons per hour). So if you divide 4800 and 5520 by 500(pm me if ya don't understand how to do the math) you get that you'll need 10 -12 of these filters(remember AC110(AC means aquaclear)).
Now in your mind try to envision a fish tank with 12 AC110s on it, I though this would look kinda funny. So that is why I
<this little guy is rolling on the floor laughing, you should lighten up and try it sometime.
This all coming from the guy that searches out my threads and craps on them as much as possible. And trust me I do plenty of math

Semperfish great post I completely agree. Some fish definitely do not like excessive current and a turnover rate that is too high is just not feasible.
Hybrid theory , Good point as well.
I couldn't agree more. At this point the only reason I would consider removing the UGF is if the Cichlids digging rendered it ineffective. I also "aggressively" gravel vac once a week (takes me about an hour).SemperFish;3783654; said:
As I read this thread from start to finish only four good arguments for higher flows seem to repeat(If I've missed any help me out).
1.Increased oxygenation of water
2.improved Mechanical filtration
3.improving biological filtration
4.Higher flows to simulate current in the fishes natural environment
Given that my Water oxygen levels are more than adequate, mechanical filtration is excellent,Bio filtration is adequate (water tests don't lie),and my Cichlids are lake dwellers and don't neccessarily want or require artificial current I'm left to conclude that for my particular application I have no need for flows in excess of 4X. It would be a waste of energy and an unneccessary expense. Perhaps I have missed something in this discussion. Is it possible that these high flows are more specific to sump setups ?
If I were to even try to come close to the reccomendations using commercially available canister filters I would need a minimum of 4 Fluval FX-5's or 6 2260 Eheim's just to attain 10X turnover at a cost of $1700.00 to $2400.00 just for filters. I'm in my current setup $200.00 dollars total(not including the pump $175.00).
If MY Cichlids render my UGF ineffective I guess I would be forced to develop a sump setup while retaining my canisters for mechanical filtration as nothing I have read or heard (so far) has convinced me that a sump is a better Mechanical filter. IMHO anyone who says cost is not a factor has way to much money.
At the risk of re igniting some of the more passionate posters to this thread IMHO sarcasm has no constructive role in an intelligent exchange of ideas. It is merely a distraction from the topic.
I honestly think that 10x is over kill in a lot of situations. I'm sure most will disagree, but I have tanks with both 6x and 15x. It doesn't make a difference that much. You still have to change the water weekly vacuming etc. I have a 240 and I removed the FX5 and just kept the wetdy and I didn't notice any difference in clarity or water quality loosing the extra filteration. I think anywhere from 6x-10x is fine.

LOL! MFK drama with the 42 yr old
I prefer to have at least 10x turnover. However, I feel that it is not needed for nitrogen conversion, but it is rather needed more simply to pick up the waste. On my tanks, the rates range from a 20 gallon long with 2 90 gph HOB's, a 35 GPH internal filter, a 175 GPH internal filter, and a 160 gph powerhead, making it a total of 19.5x with filters and an extra 8x with the powerhead. However, that tank is a growout for my payara, so it needs a lot of flow. My feeder tank has an eclipse hood, so there is only 200gph on a 25 gallon tank, and one of my 55's had 300 gph on it for a while, and now 400 gph. The rest of my tanks are right around 10-15x. However, I have had less on all these tanks in the past, mainly because I don't buy filters, just adding them when I get them for free. I think most only need about 6x turnover to prevent ammonia from building up. Usually by the time my tanks get severely overfiltered, I get a new tank for free and transfer some filters over to that.
tcarswell;3782715; said:Yeah but you are counting the manufacturers rating on HOB's that are store brand .
For a sump if you can calculate head height then yes that is viable.
However saying an ac110 actually flows 500 gph is far from correct. Real world flow is usually much less.
Oh and DawnMarie , Read the quote in my signature. Whatever you are thinking about saying crazyfish88 most likely already said
yes i did calculate in the head loss and restriction
i have a 120 gal with 1 fx5 and use 2 powerheads(one in each corner facing eachother on the back wall), and water clarity and quality are great. fish are active, not panting, have great color and disposition about them. in my other 3 tanks im only turning the water over about 5-6x with just the canister filters and using 1 small power head in each. everything is fine.
