use tap water? my tap comes out at pH 8.5 and hard as rocks... Theoretically only rain water can have a dH of 0.

you could use calcium based rocks... not the greatest idea, but works. also lots and lots of shells (a better idea)

What are the ph readings in the water your testing? Because your aquarium water usually has a natural supply of dissolved minerals which make up a buffer system to keep your pH stable. And all of these dissolved minerals together make up the total hardness of your aquarium.

How long after you get the water out of the tap are you testing? Because you will get different readings depending on the amount of time the water has sat.

Also, what ph are you aiming for?

Don't use chemicals to buffer it get crushed coral and add that to the tank over a couple of weeks till you get the hardness you want. :)

Yep that is exactly right. Mine comes out the tap some times at 9 and lowers to the same as yours. Softness where I am ranges from 0 - 3 and never been higher than that. Great place to have discus, blue rams etc. I have friends VERY green with envy because of our soft water. :woot:

I've the same prob, it reads 7ph but theres zero hardness in the water from the tap. I add crushed coral (in an old tight) and filter over it.
I'm good looking, your all good looking. But the wife tells me not to drink so much :)<br><span style='color:blue'><a href='http://www.aquaauction.co.uk' target='_blank'>AquaAuction.co.uk</a></span> : <span style='color:green'><a href='http://www.aquaauction.co.uk/otheritems-100080-Davy.html' target='_blank'>Selling stuff</a></span> : <span style='color:gray'><a href='http://homepages.tesco.net/~davyreynolds' target='_blank'>TropicalAquariums.info</a></span> : <span style='color:purple'><a href='http://www.sfc-berlin.de/Free%20Stuff/Free%20Stuff%20Pics/No%20Money%202.jpg' target='_blank'>My bank Account</a></span>

yes, shells from the beach, just make sure you wash them well first works for me every time. or you can use Davy's trick... but be sure to wash out the coral sand well.

Just a little warning. If you use coral sand it can get into the gills of your freshwater fish and irritate the gill lining. Crushed coral is heavier and so does not float through the water to cause this problem. :)

If you boil the shells too, that helps kill any bacterial contaminant.

Can't say I have a dh problem here - ours is like drinking stones some days lol!

I don't bother as most fish are perfectly able to reverse :) but you could do that.
