You always cheat on the ouija board!

I'd dismiss the old kit results because now that I use test kits multiple times everyday and they only last me a couple months maximum, I'm finding new kits match up with "old" kits. I've come to the conclusion that older kits start wandering quicker than we might expect. Looking back through 5 years of test result journals anecdotally confirms this suspicion. I wouldn't care much between the two remaining results - both are above NSW Mg level. |

Test time again this morning!
Ca - Hanna HI758 426ppm - Test 1: Old reagent (exp 11/16) 432ppm - Test 2: New reagent (exp 03/18) 433ppm - Test 3: Same reagent as above Alk - HI755 130ppm - Test 1: Old reagent (exp 03/16)!!! 154ppm - test 2: New reagent (can't remember exp, but it's new) 153ppm - Test 3: Same reagent as above Mg - RedSea Magnesium Pro Kit 1380ppm Phos - Red Sea Phosphate Pro Kit 0.02 - 0.04ppm NO3 - Red Sea Nitrate Pro Kit 32ppm!!!!! So obviously I haven't been keeping up on my water changes, look at those nitrates! I think it's having a detrimental effect on some of my corals. So I did a ~40g water change and I have another one mixing as we speak. I may do a 40g change every couple days to try and drive those nitrates down. If I do a 40g change every two days for a week that will be approx. 38% water change. Second point of this post, check your reagent expiry dates I think that was part of my issue with my parameters seeming funky for the last couple months. |

Hello All,
I recently had a large rtn/stn event and I couldn't figure it out. It started on one coral (not new to the system and spread out from that point like a wild fire. Currently the death has stopped, seemingly confused by a large encrusted sunset montipora. But up to that point it eradicated a bunch of Acropora sp. and a M. setosa. As far as all my tests told me my numbers were all in the wheelhouse. I also use a microscope professionally and could not see any unwanted pests on the corals I removed from the system. I only observed a magnificent foxface picking at the dead skeletons once algae started to grow on them. A bit of background info: I use all Tropic Marin products (TM Bio Actif Sea Salt, TM Bailing 3-part, TM K+ & A- Elements) I guess that's a lie, I also dose Zeovit Pohl's Xtra I use GHL dosers to deliver the dosing (recently re-calibrated since the death started. They were only off by 5ml/min) RO/DI system testing 12ppm on the clean side (I know I need to change the cartridges and the DI resin is pretty spent) I do a ~45g water change every 2 weeks I use Hanna Alk, Ca & PO4 handheld testers I use Red Sea Pro Test kits for Mg, NO3 & PO4 My corresponding kits test results vary quite a bit in the Ca (478ppm) and Mg (1260ppm). I performed the tests at the same time as drawing the water for the Triton vials (or at least within 10 minutes). So Triton says I am way low on Ca (323 mg/l), high on Mg (1449 mg/l), and have dangerous levels of Boron & Molybdenum. The test mentioned Mo can cause cyano, and I do have a little patch of it in the back section of the tank. So what do you all think I should do? Where is my Boron coming from? |

Scythanith, have you had a read through this article?
There is a list of Boron sources in a reef tank near the middle of the article. http://www.advancedaquarist.com/2002/12/chemistry .

I have not but I will right now. I am also going to contact TM to find out if there is Boron in any of their products I use, even in trace amounts.
Thanks! |

You're welcome.
As far as what to do about the elevated Boron, try growing some macro algae somewhere in your system, if you're not already.

Good read. I have a spot I can easily grow a ball of macro. I even have a red GHL simustick I've been meaning to use for something. May as well be this!

Way back in the day I stopped using Ocean Pure salt because I discovered it contained higher than normal levels of boron. For that reason the TM salt would be the first thing I would rule out. Get a freshly mixed batch of salt water tested with Triton to see how the base line compares.
