I found a DIY trickle filter article online and I was gonna try my hand at it. My mom works for the local school lunchroom and brings home 5 gal pickle buckets all the time my. My question is, do you think that using these buckets instead of purchesing new ones would be harmfull? I have rinsed them several times and they still reek of pickles. I was planning on soaking them in some water for a few days to hopefully remove the smell, I just dont want to end up with a fish tank that smells like a kosher dill. Or even worse end up killing my fish.
Any ideas?
