TDS --The "T" Stands for "Total"

I finally broke down and created sheets for the other two tanks. You can find them at the following URLs:

Remember, the 30 gallon tank:

I'll let you in on a little secret; all that changes is the "oid" number!

Also, before I go on vacation, the 30-gallon is going into blackout to get rid of some pesky BGA that popped up during my Christmas vacation. My nitrates never dropped very low, so I'm going to chalk up its prevalence to poor circulation caused by mulm-clogged intakes that weren't cleaned for two-weeks. I'm starting to lose faith in the assumption that low-nitrates are the driving factor behind BGA, because I've definitely experienced it with high nitrates; since it crops up in regions with poor circulation, and I've read that is another factor, I'll have to come up with a new theory (perhaps in areas of low circulation, nitrates are low in very local areas?).
