From: "June Olberding" <jdolb1@attbi.com> Hi, June! > Depending on your water source, it may also be adding nutrients. Some water > sources have good KH, GH, nitrate and phosphate balance to take care of heh.. San Francisco water is as soft as it gets I think. You can see our water report for last year here - http://sfwater.org/detail.cfm/C_ID/1456 Notice the pretty map where they show you the damn they built, destroying a large area of the northern Yosemite valley. But let's not go there. The infra-structure has been severely degraded due to neglect, and now they're spending millions or billions for restoration. The City is switching to chloramines in November. We're in an older building, so corroded lead and copper pipes are a concern. I use DI almost exclusively, adding Seachem's Equilibrium to that water in changes once or twice a month. I haven't much faith in the chemical tests. I use them because it makes my wife think I'm busy. I usually go by color and condition of the leaves. (Actually the lace watersprite tells me but I've been asked not to mention that to anyone.) I have 2 x 65watt PC flors (10k) over a 50gal and about 4" overall of the florabase/flourite substrate. Lights are on 10 hrs. per day. Temperature at 76. Fluval 404 cannister. Bottom tray filled with polyfilla and the other trays with ceramic noodles. 1 additional powerhead, which is now also used as recreation for the raspboras. When I do water changes they get excited and crowd over by the powerhead, since that's where I ciphon the water in. When I start the ciphon, they all come lining up one at a time to swim through the current. They really make a game of it. Reminds me of kids at a fire hydrant. d ------------------ To unsubscribe from this list, please send mail to majordomo@thekrib.com with "Unsubscribe aga-member" in the body of the message.
