do airstones generate enough movement within the drum to age/remove chlorine or do i need to add a circulation pump? should i add driftwood or peat to the drum to assist ageing? the water is for my planted discus tank. any feedback would be appreciated. thanks.
thanks ben. your question about water parameters made me do a long over due series of tests finding that my KH was critically low, possibly as a result of over aeration caused by the trickle filter?biogenic decalcification is my best guess, becuase its definately not lack of CO2. i wondered why the hygro kept melting, curse me and my testing slackness. maybe someone could shed some light on my problem. getting back to the drum what did you want to know? i see you`ve had vast expierience with the old pickle barrell before (impressive) any questions i`ll be happy to help. there is some heating duct up there somewhere brad and thats an excellent idea, cheers. i`ve got a 300W heater and a couple of airstones in the barrel ant so the circulation should be covered, thanks.
