I'm trying to get to the bottom of why my SPS have lost some color. I moved to a Vertex Illumina LED about 9 months ago. Within about 6 months I noticed most of my SPS starting to lose color and fade. About 2 months ago, I added my T5's back in to supplement some of the UV loss. I'ved noticed an impressive increase in color of most SPS as well as Wellso's, Acan's, Scoly's, etc. Yet a few SPS are still fairly bleached or browned out.(I know may not be long enough yet) In testing over the past few months, I've found the following; Mg is always adequately high at 1500 Calcium may be too high, usually right around 700 - is this of any concern? Alk is also usually high around 11.8(odd in that I've always seen relation to high Calcium and low Alk...) Would the high Alk have any affect? If so, best way to lower? PH is a little low usually right around 7.9 to 8.0. Best way to raise? Also Nitrate and Phosphate are undetectable. As a bit more info. I use a 3 way doser, dose Vinegar, and BRS Calcium/Alkalinity with it. Thanks! |

Your testing numbers aren't right, are you using a old test? ------------- AquaMedic 250 Watt XM 20k 2 420s Vhos 29 DT SPS Dominant 20 G Long Frag http://utahreefs.com/forum/forum_posts.asp?TID=56607&title=dionysus-tank-build" rel="nofollow - My Tank Progress =) |

They are new - numbers should be right. Alk of 11.8 is in dKH or 4.22 meq. if that is the one you are questioning? Thanks! |

This will help you understand the relationship between the two and how to fix any current or future problems. http://www.advancedaquarist.com/2002/11/chemistry#section-0" rel="nofollow - http://www.advancedaquarist.com/2002/11/chemistry#section-0 ------------- It's Not a Hobby It's an Obsession 150&210 Gallons of Madness and.

I was just thinking your alk wouldn't be 12 with calcium of 700. ------------- AquaMedic 250 Watt XM 20k 2 420s Vhos 29 DT SPS Dominant 20 G Long Frag http://utahreefs.com/forum/forum_posts.asp?TID=56607&title=dionysus-tank-build" rel="nofollow - My Tank Progress =) |

Yeah, I would think the same way but definitely is with two different test kits. Cutting off all dosing for now until both drop and then will figure out amounts to level out. Thanks! |

water changes will help balance things out! Good luck. ------------- AquaMedic 250 Watt XM 20k 2 420s Vhos 29 DT SPS Dominant 20 G Long Frag http://utahreefs.com/forum/forum_posts.asp?TID=56607&title=dionysus-tank-build" rel="nofollow - My Tank Progress =) |
