			 YOu are better with the Kh not more than 10 as this can bring a lot of RTN STN in your coral.  Too high Kh is a risk for this condition. 
		
	
		
		
		
		
			Natural sea water is between 6.5 to 7.5, no 11 or 12. It is also best to maintain a mid range value for the Kh because if your test is off a bit, it won't be so drastic. If you keep it at 12 and your test is off you might reach 14 or more....even 11 is incresing the risk of RTN. Quote:

			 Good to know Danielle. The alk is that high in the salt I use. Double check and it matched.  
		
	
		
		
		
		
		
	
		
		
	
	
	Well if that's the case I'm almost where I wanna be with my alk. Just a little higher and I should be good.  |
