			 Hi there.  My tank has cycled and i just added 2 clown fish to my tank.  My tank size is 66 - 67 gallon.  I'm showing good readings for ammonia, nitrite, nitrate and PH is 8.2 or 8.3.  I'm just wondering about my KH (alkalinty) which is showing alittle high.  I'm getting a 130 reading and my test kit says anything over 125 consult with a aquarium specialist.  Is this going to harm my clown fish (tank bred)?   Also, I have fiji cured live rock which has some green hair like algae on it (or so i think thats what it is).  There is a bit of it and it was on my live rock since i got it and i'm wondering is this a problem i need to worry about?  Also, brown stuff showed up all over my rock a couple days before i bought my clowns last night and i'm just curious will this hurt them?  Any help on this would be greatly appreciated,

			 130 ppm is equal to about 7 - 7.5 kH, which is about right where you want to be.

			 I think I have the same test kit as you... Hagen.  They recommend a really low level for KH but most people keep it at a higher level then what they recommend.  Here is a calculator I have found that has helped me out a lot...

			 130 ppm is on the bottom of what I would reccommend.  Most people understand alkalinity when measured in degrees of carbonate hardness or dKH even though there are several units to measure it in.  I prefer to have my alk around 9-9.5 dKH. 
		
	
		
		
		
		
			
		
		
		
		
	
		
		
	
	
	Take a read through the guides in my signature on hair algae and chemicals. They should help answer a lot of your questions. ![]()  |
