filtration

[Ant62]

Hi all..
Ive decided to have a go and move on up to the bigger fish.
Im used to keeping wild gibberosa up to 14inch in size and that was my last big project...
I stepped back down to a community setup due to ill health etc and now i find myself wanting to try something on a bigger scale for my last aquarium.
So im thinking of a 700ltr setup with a BGK and either a fire eel or an arowana.

But im looking into the filtration side of it all.
My way of thinking is a sponge across each back corner just like the HMF with bags of ceramic media behind the filter sponge and airlift....

Or.

I have two fulval 306 canisters doing nothing so i thought that i would sponge the corners just like the hmf and run the filter intake behind the sponge with bags of ceramic media behind..

The out lets of each filter would just flow under the surface....

Imput much appreciated....

Im a big fan och showerfilters and moving bed sumps and have never tried hmf filters at all. The fluval 306 i would say is to small for a tank that size and i would not go with an arowana in that tank since they get really big and grow fast. An fire eel would be ok in 700L with proper filtration and wc schedule.

Hi.....whooooooops..
Should have been 2x 406 fluval canisters and not 306.....
Big finger syndrone.....

I have used HMF up various projects but not something of this size....
I have seen people place their inlet in a long sponge roll in various freshwater setups but not on a big fish setup perhaps theres a reason for this...
As for WC i would.probably remove 15/20% every 7days as per my gibberosa setup....

You have to change at least 30% twice a week to handle the bioload of fishes in this size. They produce alot of waste. I change 40% twice a week for my cichlas and they are three big fishes between 40 och 50cm and is going in a 2600L pond. With a bead filter and a showerfilter with 50-60L biomedia

Your welcome. When i first started with i had to learn filtration again because i came from malawicichlids and only used cannisters. I have a 700L growout tank with a small ray and some other fishes in and thats being filtered by an fx5 an eheim 2262 and a 130L showerfilter with 60L biomedia and is runned by a 10000L pondpump.
