I went in today and tested the system water again. I was aghast to what i discovered. Their guy had been in today and did a PWC
(unknown how much) and...get this...ADDED FISH AND CORAL. He added this Goby to replace another that had died
And a coral which is sure to die. Unbelievable. He didn't charge them because he got a deal on some dental work from them (it's a dentist's office). Anyways, here's a full water parameter report:
Nitrate test kit #1 (purchased 1/1/9, almost empty) - still 160ppm, but at least it only read 40-80 after the shake (first pic) but then off scale at 5 min
Nitrate Kit #2, recently purchase (for verification), Same results
Both vials side by side, #1 left, #2 right
Phosphate about the same
And silicates negligible
Other test parameters:
7 (5 deep blue, 6 turned it green, 7 went yellow, same as before)
Temp 79.5 (I replaced the dead battery)
Salinity 38.5 / SG
As for Calcium, if I understood the Salifert test and performed it properly, it's at around 600-625 ppm
. Maybe someone can help me out on this one, I drew up 1ml in the titration syringe and went one drop at a time, swirling it, etc, sometimes a couple at a time, until I eventually emptied out the whole syringe. I refilled it with 0.1ml and went through that. I refilled it with 0.2ml and went through about 3/4 of that and it finally turned over to purple then blue. Each time the black head was at the line for the levels I just gave. I've got a pretty good scientific background so I'm pretty confident I did it correctly. So if the formula is (1-level on syringe) x 500 = Calcium level, and "level on syringe" being what is left over after it turns blue measured in mL (assuming you use less than 1 syringe of vial 3) and I used 1.25 ml (an excess of 0.25ml above and beyond the initial 1mL) then "level on syringe" would be -0.25 giving 1- (-.25) x 500 or 625. That seems high and the opposite of what I expected, but who knows if he dosed the tank after the PWC
So Nitrates are still the biggest problem, Temp is OK, pH still low, SG
is high, Alkalinity could come up a bit, phosphates are high.
Flow rate is quite low, he mentioned that it used to be significantly higher. I mentioned that if the power head had not been taken apart and cleaned, it should be, at least once a year if not more often. I also suggested adding one or two powerheads.
I'm going in there on Wednesday with the new LFS
guy I turned him on to, he will probably switch to his service and I will assist and learn.
Anybody want to buy a gorgeous Unicorn Tang?
