Mandinga Posted September 23, 2011 Share Posted September 23, 2011 Check your magnesium! I'm a lazy man and don't check my magnesium until something looks off...what a huge difference keeping my mag in check makes! Without the magnesium, the calcium and alkalinity are not able to be used properly by corals for growth. Plus, calcium precipitate will build up super fast as the calcium will keep dissipating from the water column.

nelsz3 Posted September 24, 2011 Share Posted September 24, 2011 so whats the best test for mag? Link to comment Share on other sites More sharing options...
pantherguy30 Posted September 24, 2011 Share Posted September 24, 2011 Elos works great as long as it's not too old. I've had test go bad within a few months. Maybe I contaminated them?? If I read off I have a shop double check my results before I add anything. Learned the hard way the first time:-( Link to comment Share on other sites More sharing options...
impur Posted September 24, 2011 Share Posted September 24, 2011 Reef Crystals keeps mine about 1425 with weekly WCs. I use salifert test kit. Link to comment Share on other sites More sharing options...
Smann Posted September 24, 2011 Share Posted September 24, 2011 Also don't forget the ratio of Calcium to Mag, same in our bodies, 3-1, so if your Calcium is 425 your Mag should be 1275 or close, 450-1350 this number is more important that each individual #. I have Neomag Mag Crystals in my calcium reactor along with regular water changes to maintain the balance between the two. I agree though sometimes we forget to test until things look a little out of wack, the Saifert test kits are good for several years and thats probably why they last, I ordered a new one then realized my old one was dated 2013!

reefboy Posted September 27, 2011 Share Posted September 27, 2011 natural seawater is 1200-1300ppm so you want it at least around that level but I dont think you need much higher then 1400ppm Link to comment Share on other sites More sharing options...
