Hi,

cheers axl

Hi Axl. I don't know a lot about ammonium sulphate, but a google search revealed the following:-

12.4 Ecotoxicity

Harmful to aquatic organisms. Increases in pH above 7.5 will lead to an increased load of non-ionised ammonia which is markedly more toxic to aquatic life.


I really don't think I'd be inclined to use the drum to age water for your precious discus. Try to get a food grade drum. The plastic will be much safer.

Hey,
thanks for ya reply, where would you suggest that i start looking for a grade food 200ltr drum????

axl, try a coke bottling plant, i have gotton 55 gal drums from them before, sometimes they just throw them away.

can i ask what do you look up in the yellow pages to get a food grade drum? if anyone else has bought one in sydney can someone suggest a handy place? I've been to bunnings and they are quite steep...i don't think i can afford those...
