After soaking for almost 24 hours, the water in the bucket has gone from pH 7.6 to 6.6, KH is down to 3, GH is 7 down from 10. I intend to leave it alone for 4 days. Once I very carefully decant the water from the sediment, will the water parameters remain stable after introduction into the aquarium? I'm mostly concerned about the pH. g. kadar ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
