u could always just top off ur res and not dump anything i've got 1 res i do that to as it's hard to change and i don't see no diffrence at all i just let it get real low and then just top it off every 2 to 3 weeks and i have'nt had a problem with anything and other than u being stealthy the bag is a good idea if u get the bags i use to work with u buy them at home depot in a big yellow box it's real heavy duty for construction sites thick this would be good if nothing else but to block out light as i have 1 5 gal bucket i do this with not for what ur trying to do but to keep light out as it's not like a reg heafty bag but alot thicker
palerider7777 Reviewed by palerider7777 on . Question about DWC In using the 5 gallon bucket setup, airstone, etc. in a cabinet setup, it seems it would be a hell of a lot easier to insert a black hefty bag into the bucket and then fill it, then when time for water change just fill another bag up, remove the old one, drop in the new one, throw your old stuff out. Would this be possible or has anyone tried it?Anybody see anything wrong with it? Would this work? Also would allow for a darker bucket to reduce root rot, am i correct here?
