Some pre-D day parameters, amidst scouring books on Down Syndrome (sure hope this comes out either for a short case or for essays .. but life is never a bed of roses, is it?)
Alkalinity = 2.23 meq/L (normal = 2.9-3.2)
Ca 2+ = 524 mg/L (normal = 420)
Sr = 16 mg/L (normal=16-22)
PO4- = 1 ppm (optimum = 0)
NO3- = 50 ppm (optimum = 5 or less)
Quite F*ed up, is it not? The cations are easily corrected, but the anions ... arghhhhhhhh. What can I expect, after half a year of no water changes and yet massive doses of phytoplankton and zooplankton? Damn those sponges, flame scallop and razorfish, hahahahaha.
Just dosed a total of 0.9 meq/L of buffer into the tank to raise alkalinity to 3.13 meq/L, no wonder the calcium is sky-high - the coralline algae aren't able to take up calcium because of the low alkalinity and high phosphate, and the pH has been swinging from 8.03-8.4. Not good. Time for a massive (50%) water change sometime in late April ... the dumbass Pura NitrateLock resin is OBVIOUSLY not doing its job of keeping the nitrate levels down, what a complete waste of $.
I think this is the first time I'm using these test reagents after winning them from a photo competition. Saw a really phat equipment made by Hanna Instruments the other day though, it was so OOOOH! Hate to think about the price however. It's a portable colorimeter (size of half a laptop) that measures dozens of ions electronically. Wow, no more titration!
