OK some updates/quick synapsis/lesson learned:
I had a bad fall "healthwise" -so did not test much/at all and performed reduced water changes as well. Result= Lost many of the acros/sps corals - but softies and other corals and all fish doing fine.
So started getting serious about the tank again 1-2 weeks ago and my Alk was off the charts according to my Hanna checker ( read 300)= Freak out time. Then I realized the reagent was 6 months expired. SO, ordered new reagent. In the meantime, while waiting for the new reagent. I tested my ca,mg and they were low = 322 and 1050 respectively. Added Calcium chloride Bulk reef solution to raise ca+ 50 ( max per day). Could not add any Mg+ - I was out of Mg chloride and had only Mg Sulfate. So, ordered Mg Chloride. Lesson= watch your inventory on supplements.
So, while trying to figure out how my ALk got high I checked my salinity = 1.028- hmm - I purchased a new refractometer a month or 2 ago. SO, found my pinpoint salinity calibration fluid. Yep the refractometer was calibrated incorrectly from the factory- it was reading high- so I adjusted it and now my tank water was good= 1.024. So one issue solved. Lesson = don't assume the factory setting on equipment is correct.
I did some reading and talked to a few friends and it seems the Hanna ALK reagent that is 6 months past expiration date should not be all that inaccurate- so I went up to LFS - had them test. Their kit said 16 DKH- so ya now I am very concerned- debating on how to lower my ALK. I also had brought my Reef Crystals water that was in my mixing station to the LFS I was using to see if it tested high as well and was the reason for the Alk being so high- it tested over 14. So, ya- I am thinking - problem is not solved - but at least the reason for the high Alk is found. SO, I purchase new salt to mix = Red Sea blue bucket- says it should mix to around 7 DKH. Well - I mixed it up and did a ALk test and it read 12- WHAT !? Also tested the new water for Ca+= 515, and Mg+ 1350. Today I got my new Hanna ALk reagent and retested both tank and the new Red Sea water in my mixing station- the tank read 10.6 DKH and the Red Sea water tested 7.8. LESSON= make sure your reagents are not expired and don't assume someone else's test kits are all that accurate either.
So, will be doing a 30 gallon water change today using the new Red Sea salt - then slowly adding some Ca+ and Mg+ supplements over the next week to get back to optimum reef tank specs. Tank should be ready to go just in time for the LEAR fragswap!!
