SRC Member arcanehacker Posted February 16, 2004 SRC Member Share Posted February 16, 2004 I dun see why since they are all cloth and soup bags are made from good quality ones because human's life are at stake.. In fact I find them better coz you can use for finer medias. Quote Why do we use "My 2 cents worth" when 1 cents are not legal tender in Singapore anymore? Shouldn't it be 5 cents worth?

SRC Member damsel-in-distress Posted February 16, 2004 SRC Member Share Posted February 16, 2004 I need some fine-media filter bags. Where can I get these cloth and soup bags from? Quote Link to comment Share on other sites More sharing options...
SRC Member Eric Posted February 16, 2004 SRC Member Share Posted February 16, 2004 I need some fine-media filter bags. Where can I get these cloth and soup bags from? Aquastar at Yishun Central sells them at $2 per bag. Quote Link to comment Share on other sites More sharing options...
KingFish Posted February 16, 2004 Share Posted February 16, 2004 Don't think cotton bags will last very long in saltwater. Suggest you to get the bags they sell at the LFS, its rather cheap, about $3-4 a piece. Better that than coming back home to have your filter media all over your tank.

SRC Member arcanehacker Posted February 16, 2004 SRC Member Share Posted February 16, 2004 Aquastar at Yishun Central sells them at $2 per bag. dunno if its the same one but the last time I use that, it tore. Their $2 ones are still nylon but small holes. Quote Why do we use "My 2 cents worth" when 1 cents are not legal tender in Singapore anymore? Shouldn't it be 5 cents worth?

KingFish Posted February 16, 2004 Share Posted February 16, 2004 Its a simple matter of biodegradability. Logically, cotton being organic matter is easier to breakdown of its hydrocarbon makeup than synthetic materials such as plastic, polystyrene, et cetera. Cotton will take about 1-5 months in various conditions to biodegrade while Styrofoam will take forever. capisca? Quote Link to comment Share on other sites More sharing options...
SRC Member bawater Posted February 16, 2004 SRC Member Share Posted February 16, 2004 You may try it and the worst is that the media is spilled all over the place. i tried the coconut squeeze bags long ago and stayed away from cotton from then on. Spotlight have some nice bags (either polyester or nylon) which they keep for decorations near the small coloured boxes for wrapping gifts for a few dollars which i use - so far they have lasted well over 12mths. or watercircle as some fine mesh media bags. "Cotton will dissolve in seawater" and is used in aquaculture for that specific purpose- http://www.fukuina.com/shellfish/flexmesh_socking.htm and just some generic news to back that up. http://www.tis-gdv.de/tis_e/ware/fasern/baumwoll/abb9.htm Quote Link to comment Share on other sites More sharing options...

fishchemist Posted February 16, 2004 Share Posted February 16, 2004 Basically both nylon and polyester material will still be weaken in an alkali media. Nylon consist of amide linkage while polyester consist of ester linkage, these bonds undergo alkaline hydrolysis(breaks down) under alkaline medium. However, the temperature in marine is usually low, the rate of reaction is usually very slow. Therefore, IMO changing these bags once in a few months shouldn't be an issue.
