Would this work to increase my water volume and filtration????

Hi Guys,

ATM i have a 400L tank with
1x 1400L Canister Filter
1x 1000L Canister Filter
1x Oscar
1x Geo Brasilineses
1x Green Sevrem
2x Barramundi

I do water changes every sunday and i realy havent had dramas with nitrates etc.

What i'm asking is if i can make a 200L Food grade drum into a massive filter and plumb it into my tank in the way the pic is drawn

So to give a run down on the setup, water from the Tank will flow under gravity into the 200L drum that is filled with pot scrubbers at the bottom is a small gap for clean water which is sucked out by both canister filters and polished and filtered more before returning back to the tank.

The only problem i can see is if the 2 canisters cant drain enough water out of the 200L drum as it fills from the tank????

let me know what ya think

peace out

Problems include:

A) To prevent water spilling out of drum, can -
i) raise intake to just below water surface, or
ii) add weir between intake and drum, at height of water surface, so water only get into drum from height of water surface / weir, or
iii) raise drum so water level in drum same as water level in tank. If choose this last option, scrubbers will now be submerged media rather than wet / dry trickle media.

B) Depending on design of canister filters, they very likely not work if top of canister filters become raised above water level inside drum. So need to lower canister filters more, or raise drum up more.

C) Outlets from canister filters are underwater - if power goes out, can siphon water out of tank and make puddle on room floor. So, either keep outlets above water surface, or add one-way valves to canister filter outlet pipes.

i'm all about visuals dont work to well with words

yes, you could, but I wouldn't.there is too big of a risk of flooding the way it is. if you lose suction, the water won't drain into the barrel and the pumps will empty it into the tank. do some reading on HOB overflows, other than getting the tank drilled that's probably your best bet.

Yeah cheers, took my idea to a bloke out my way who builds glass and arylic sumps of all weird designs and he said cause these food grade containers are water/air tight set it up just like a canister filter with an internal pump and ensure i plumb it all up making it air tight again so i might study my canister filters i have and look how they do there stuff and copy that and see what happens.

any other ideas will still help caus ei can get these drums for $10 each so making a few would be easy.

hey i see your in aussie too. im looking at doing something very similar. take a look at this

http://www.paramountbrowns.com.au/h...ts/storage/tubs-containers/pickle-drums-200l/

we got paramount browns in SA, they sell just random stuff, all sorts of hardware. if you used one of these, it has a lid so will prevent overflow in power failure just like your typical manufactured canister filter. im also thought about putting a submersible pump in the bottom hence you might not need your canister filters too. that way its all sealed and then you got one big BFG of a canister filter haha

Mitch,

Yeah cool man that's what I have ATM but only played $20 for it, I haven't set this up yet as I don't have the room to do this and I might wait till I have a bigger tank. ATM I'm running 2x 2000Lt canisters.View attachment 868043
