wasp Posted October 8, 2006 Report Share Posted October 8, 2006 but does nz nsw have differing levels of potassium than say around typical tropical reefs? or is it the same level worldwide? NSW at many reefs has potassium levels varying between 380 to 420. As I recall, Craigs testing of our NSW found levels of 380 ( i THINK ). If it was 380, but we have to dilute the water 10 or more percent, we would end up with a level around 340 ish, lower than the lowest normal range at a wild reef. Does that matter? Don't know. But dosing it is cheap, so for me anyway I'm dosing some extra and this appears to be doing good. But I'm only dosing a little as my test kit has not yet arrived. When that gets here I'll have a better idea where I'm at. Also, to me anyway, it never can hurt to have the water as close as I can get it to NSW. Another thing to consider though is that millions of years ago the sea was not exactly the same composition as it is now. And the corals we have now, or their forebears, were also around then. So there is some room to move, mostly in favour of how things were before. Quote Link to comment Share on other sites More sharing options...
wasp Posted October 8, 2006 Report Share Posted October 8, 2006 lend me your pottasium kit when you get it and i will test the theory. Yes that will be an interesting one, particularly as you use ASW. The best way to do it will be to test some of your new, unused water, and test your tank for comparison. As you have been getting good growth in your sps, it should be a fair test. Quote Link to comment Share on other sites More sharing options...
reef Posted October 8, 2006 Report Share Posted October 8, 2006 you have been getting good growth in your sps funny you should say that as i never think anything grows until i see old photos or someone comes around that has not seen the tank for some time.

wasp Posted October 9, 2006 Report Share Posted October 9, 2006 Doubt any of the shops will get one. The only one I know of currently marketed to the aquarium hobby is made & sold by Zeovit. Quote Link to comment Share on other sites More sharing options...
