I use 6" net lids on 5 gal buckets with a 40 gal rez.

the tub full is just for washing and Ph ing, usually stops rising after 4 or 5 days of soaking, but this is way off. even after 4 days

thinking about going down to the river and gettig a bucket or two of washed river rock off the gravel bar, couldn't be near as bad as this H crap

time to medicate
