I have a High pH and Hardness in the tap water and have been looking at how I could reduce this by a degree i.e pH down to 7.5 which should benift plants and fish, although apparently farmed fish are used to this level because they are either grown in it or are in it the shop.
I found this product on the net.
http://shop.ionicsystems.com/htdocs/a ... _line_De_ionisers_59.htmlNow if I have it right the mineral content determins the pH and Hardness so If it removes 99.99% of minerals then I should have a neutral pH but what about hardness??
Am I correct in thinking there are minerals in water that benifit fish and therefore these would be removed?
IS there anything that could be added to provide these minerals?
I have considered RO water from the LFS but at 50p a gallon it would work out more expensive than the unit. In a year.
I also have a friend that may be getting a large tank so could halve the cost again.
Any IDeas??
