......as far as your low pH problem, with the alk sitting at 10DKH, ......... poor aeration both in the tank/tank room are the major causes of poor or chronically low pH. Tank lid, no sump, lack of surface aggitation, poor room ventilation. There is also overfeeding/stocking, poor nutrient export and so on. ......
wow, thanks steve, what a great answer.
overfeeding / overstocking : guilty on both counts. i'll cut down the feeds, but i ain't doing a cull. the wife obsessively buys stock and loves feeding, but she's away for a couple of months, so i can control this at least.
poor aeration : i wasn't aware that the tank needed aeration, but it has a protein skimmer and powerheads. yes, there's a lid. no sump. no surface agitation. poor room ventilation. i didn't know this was trouble.
poor nutrient export pls explain
