Thanks tcarswell!

You will accumulate enough bacteria to feed off of the amount of ammonia and nitrite being developed by the stock in your tank. So you can have 1000 liters of bio media, but you may only utilize 10% of the media.

I hope, to one day, calculate how much media is needed at a given flow rate for a certain amount of ammonia given per day. That can't come soon enough. I may also add a velocity test. You can have 20 seconds of contact time, but depending on the diameter/width of the structure, the velocity could be higher or lower. I think there will be a happy medium where velocity needs to be within "this range". Any higher or lower will not be effective.

If you really want to start thinking and scratching your head. I just made a chart which tells you the contact times for bio media from 5 liters to 100 liters and 100 gph to 4000 gph. I will make another thread and upload the pictures, its pretty interesting to see. I have calculated the figures about 4 different ways and come up with the same answers that are within 1-3 seconds of each other.

Send me that or a link I gotta read it

To the OP. CPR makes wet dry filters for tanks smaller than yours and to 400 gallons. They only use 144 liters of bio media for a 400 gallon aquarium. That should through out with massive wet dry setups.

Derail, it has everything to do with his thread. Im letting him know he doesn't need to build a HUGE sump.

I am not going to beat it because I am trying to save members from people like you that say, bigger is not good enough go huge! Without performing any calculations at all.

Obveously you have been proven wrong.. lol. If you never said "PAL" I would be a lot nicer.


Two Fx5s equal 11 liters of bio media at 1200 GPH with 20 seconds of contact time. What happend to the 100-200 liters of bio media using a huge 80 gallon sump?


I am, but im in no rush.

Look before your pursue this bitter aspects (seems a fitting name) know that the guy your arguing with did a web page about FX5's .

to the OP.
just go check out the DIY section of the forum on a good sized sump design. that will be the cheapest abd best filtration for your tank. it works a lot better if you have a PH inside the display for better movement od detrius to the overflow. or better yet a HOB or canister in combination with the sump. just depends how much you want to spend.
if you can find a good priced Fx5 on ebay, those are good too. but youre gonna eat the shipping. moanalua pets and pets plus carry Fx%s for a decent price, but it might still be more then you want to spend. then again, you could always go for something like 3x ac110 HOB filters, and that should do it too. theres lots of ways to go about doing it.
im out

WTF!

So, you go from a 80 gallon sump which can hold 110-240 liters of media, to two Fx5 which will hold 10 liters of media @ 1200 GPH, to 3 AC110s which in total will hold 3 liters of media @ 1350 GPH. I am not saying they won't work, but you tried telling the guy that 80 gallon sump is the way to go and he should actually go bigger and then you tell him to get 3 Ac110s that hold 3 liters of media altogether....

To the OP. DO NOT LISTEN TO THIS GUY!! He has no idea what he is talking about!!

LMAO PWNED

Edit Just to add something for the OP

Check out the DIY thread section for some amazing sumps. They have all the info you need there to build an efficient reliable sump. You came to the right place ! Just the wrong section Im kidding ofcourse best of luck to you !

Go with the sump 808. Canisters like the Fx5 are great but hella expensive. I found this thread very interesting.

I wouldnt recommend CPR their inlet hose are retarded...i bought CPR3000 for $1000 shipped....mos def not worth the $

I personally like larger sumps just for the safety factor in the event of a power outage and back siphon. Small sump = flood if the power goes out. You have much more room for error if you have a larger sump. For me it's not a matter of bio/filtration capacity, but the ability to hold extra water. Although a good tip I saw on here is to drill a hole in a return line just below the water level. The hole will break the back siphon as soon as the water level drops below it. This is a good precaution, but not full proof because if something clogs that hole, the back siphon will continue.

I currently have a 270G with a 35 gallon sump and I constantly have to make sure that the water level is high enough so that my return pumps aren't sucking air, but not so high that the sump overflows if the power goes out. It's a pain in the butt. IMHO, when it comes to sumps, bigger is better. Constantly tweaking the water level in the sump is a pain! (I'm actually looking for a larger acrylic tank for a DIY sump project; PM me if you have an old 60 to 120G that you're looking to get rid of).

For what it's worth, I like to go with a sump and canisters. The canisters for polishing and the wet/dry sump for bio-filtration.

Thanks Hot Slime about the thread compliment.

You bring up an excellent point. I didn't take that to tightly into consideration.

I am working on building a sump calculator in Microsoft Excel which takes a lot into consideration. Should end the sump size debate. Demo Here
