			 For the last few months I've noticed my ph has been 8.6-8.9 
		
	
		
		
		
		
		
		
			Alk is at 9.5 dkh My ph probe is calibrated and working. What would cause such a high ph and should I do anything? I have a kalk reactor, But i havent ran the mixing pump in over a month now. Today i completely bypassed it. Last edited by MarkoD; 10-27-2013 at 12:57 AM.  |
