hey shaggy, well done with the project.
could you draw up a cross section off the insides of the canister as to understand how you have set up the filtration in there.
thanks mate.

Sorry for the delay will write it up this week

Went to Bunnings today and could not find the black fittings with the blue sealer on them...which area of Bunnings did you get them from?

By the way...great idea.

Thanks noddy and fives.

They were in the retic section.

Remember to design it around the size of the pump you are planing to use. Also make sure you grab a screw top lid with a seal as it will leak otherwise.

On my test I used crushed rock but you can put what ever you want. Personally I will be using a combo of wool, crushed rock and carbon.

I think it cost me about $50 for all the fittings minus the pumps to build two +50cm tall canisters. That included silicon and super glue!

I will try and go to bunnings this week and take photos of all the fittings I used.

Here are some pics of all the parts used to create the canister.

Gday Shaggy

I've been reading about a DIY Coil Denitrator. With some minor modifications to your design you could easily make one of these.

It's an interesting read, check it out -

Am very impressed Shaggy

[shaggy]

Thanks madasa

Will have a read during my lunch hour dazza

Here are the plans (finally :roll: )

Warning all electrical work must be done by an electrican

Looking good Shaggy

With regards to the power switch it might be worthwhile mounting it above the hole where the cord enters the canister. Else if a leak was to occur at that point it'll follow the cable down the switch which is 240V 8O .

Regarding the order of your filter media ideally you'd want most of your mechanical filtration done before the bacterial filtration. So if possible the water should flow through the filter wool first. When it comes to cleaning you'll just have to change the wool as there shouldn't be too much build up on your bio balls and crushed rock/coral.

Keep up the good work!

Good point with the the power.

The only reason for the bioballs was to raise the first layer of wool off the bottom.

Had a read of the link and yeah it would be pretty easy to make. Unfortunately I don't have excess amounts of nitrites to have use for one :cry:

Hi shaggy good diy project mate just out of intrest what size tank would this be suitable for using this size pump?

Keep up the good work!!

Super glue i always thought that stuff was toxic for fish and yet you are using it to help seal the fittings.

Sorry if im wrong was just enquiring as that is what i thought. NO pun intended on the filter as i love the idea.

The idea with DIY Coil Denitrator is to help minimise the amount of maintenance needed longterm (cleaning filters, water changes etc). If you're will to experiment with it I'll buy one of ya :wink:

Perhaps swapping the bioballs with some stiff sponge is an idea? Should be able to support the weight of filter media above and act as a better mechanical filter. Will also prevent the filter wool from clogging as quick thus preventing a drop in the flow rate.

Once again top work so far

What brand of superglue did you use?

[Noddy65]

I made one today. Just waiting for all the joins etc to dry.
Im going to fill the bottom with scoria and the top with cotton wadding from Spotlight.
Its mostly to act as a secondary filter in one of my tanks.
Ill probably put a prefilter over the intake to try and catch as much of the big stuff as i can.

Super glue is bad so be very careful! The reason I used it was to add strength to joins. The super glue should at no time come in contact with the water. Probably should have mentioned that :oops: I basically joined with silicon but used superglue on the outside edge of the join as to not come in contact with water. I did this because I found silicone didn't make a very strong join. If anyone has any recommendations on other products please let me know.

The pump does about 500Lph. I have planted tanks and keep fish that don't like high water movement. I think the higher the Lph the better but I believe the same allpies to the size canister. You would have to try your self but I'd use retail canister specs to see what size canister and pump you would need.

Dazza know of any pumps that only do 1 to 1.5Lph?

Noddy did you use super glue to strenghten joins or some thing else?

Thanks guys for all the positive feed back. Please post any ideas as this is still a work in progress

[ant747]

couldn't you use plumbers glue? i mean when they plumb houses they use that and it comes in contact with the water we drink and if you keep fish, when ever you do a water change...well you see where im going.

[Noddy65]

Hi Guys
No I didnt use any superglue, im hoping that the plumbers glue and the silicon will help hold it together.
