Large filter media bag


BaZ

Recommended Posts

I'm wanting to sink a big bag of limestone into my sump and am having trouble finding a suitable bag.

I currently have oyster shells in a large onion bag (5kg bag I think dntknw.gif ) but the weave of that that bag is too big for the limestone 'gravel' I will be using.

I'm under the impression that some fruits or veges come in large bags which are a nice fine weave similar to a media bag, but am yet to find any.

Of course I'll happily buy a purpose-designed bag from an aquarium store but I am not sure if they come in a large size. Does anyone know?

i've seen them at fleminton (i think that's how you spell it) markets.if you know anyone who lives near there maybe they can pick one up for you and take it to the meeting if they are going..

Mike do spuds come in a fine weave bag? One suitable for holding gravel? It's like coarse coral sand I guess.

Not sure that I've seen spuds sold that way around here, but perhaps I'm just looking in the wrong shops.

Duck stockings should work but like you said they would need to be big zipit.gif

I wrap my media up in plastic flyscreen. It's almost perfect as it does not 'wet' and the water flows through it very easily. I sit the media on it and wrap it up leaving the top over. I then fold the top over in the sump. My bioballs are like this. I also have two sacks one on top of the other in my deeper sump. This way I can grab the top bag and rinse it out in the cycled water.

If you wanted to go one step further than mianos' great suggestion, perhaps sew flyscreen into a bag with light fishing line?

I'm sure I have seen large bags that would be suitable in material and craft shops such as Spotlight (?)

Surely they have a zillion different materials of various weave sizes that could be made into bags easily enough (curtain netting etc...)

I was going to hand sew them up but I initially cable tied the top closed but I found it stays together fine without the cable tie and it's more convenient left open.

Ehiem make a large filter bag for there big barrel filters. I use them for the pond matrix I have in the mimi reefs. The problem with some of the bags is they brake down after a while and what ever you had in them ends up all over the filter. I have had the Eheim ones for years with out any problems.

Thanks for the ideas clap.gif

I'd already considered flyscreen but I think I'd need to be sewing it into a bag/envelope kind of thing as access to this sump is limited and I'll be adding this with one hand.

The eheim bags sound good Nigel. Have you seen them somewhere recently? Any idea of price?

I think Auburn Aquarium or Ben at Age of Aquariums should be able to get them for you. As for price it was a long time ago I brought any and I got them from the importer I think they where about $15 each. There is also washing bags if you can find one big enough they should not brake down.

G'day BaZ,

I use laundry bags all the time for Matrix and the like. They are quite a good weave size and thinking that once in place they won't be moved very often the laundry bags are micky mouse! $2 shops, K-mart, Big W has em in all sizes.

ps:

If your worried about the weave size do what I do, slip one bag inside another, the holes never line up so you effectively halve the weave size! thumb.gif

If you want something bigger than washing bag, go for a bag used for basket balls/volley balls.

I got mine from Big W in the sports section. It's REALLY BIG. I think it's made of cotton and will break down eventually.

HTH...

I have the same query carlos. tongue.gif I have about 5 of these laundry bags at home that i would like to use in my sumps.

Will the zippers rust?

The bags that i own, have the zippers painted but i doubt the paint will last very long in water.

any ideas?

thanks youngy

BaZ...grab the sewing machine and wiz up a pillow case type shape (basically 3 straight runs) using fine curtain netting. Very cheap from Spotlight (or the like). Go the extra mile and put a draw string in the top....very easy.
