...I knew that a calcium reactor and possibly a kalk reactor were in my future...especially after adding 15 or so SPS types over the past 4-5 months. I normally check my water chemistry on a bi-weekly basis and in the past I've been able to maintain the following ranges with bi-weekly 10 gal water changes and suppliments of Seachem Reef Advantage/Builder/Magnesium and a steady slow kalk drip:
temp: 76-82
ph:8.0-8.3
nitrate: non-detectable
phosphate: non-detectable
calcium:425-450 ppm (4 month average)
alkalinity:8.5-10.0 dKH (4 month average)
magnesium: 1200-1300 ppm (4 month average)
In the past 4-6 weeks I have seen a steady decline in the alkalinity as well as the magnesium dispite increases in suppliments for both. Everything else has remained relatively stable but I am finding it difficult to establish much less maintain alk & mag...I have increased the amount of the suppliments and I recently switched from Instant Ocean salt to Oceanic...
Here are the results from todays testing:
temp: 77.9
salinity:32ppt
ph:8.0
calcium:425ppm
alkalinity:8.3 dKH
magnesium:1190ppm
I still drip Seachem suppliments and kalk 24/7 to replace all evaporation but as the SPS continue to grow and as I continue to add more frags the maintenance of desired levels becomes more difficult. I am already nearly double the suppliments that I have used over the past few years and I don't think Seachem suppliments for mag/alk/calcium will be able to keep pace with consumption!
So....its time to focus on the addition of a calcium reactor and possibly a kalk reactor hooked up to a automated top-off system.I knew the need would increase as I added SPS types...but after a few months of carefully watching the numbers I'm convinced that I need to make a change in order to continue providing decent water chemistry for my evolving reef. Ain't this hobby just grand...there is always another expense just around the cornor and new adjustments to make!!!!!:thinking:
