Need a steady Ph - Look
No Further!
The article by David Hulse in the January
edition of Koi Carp featured the need to maintain a steady Ph value and
explained at length the virtues and issues surrounding the problem. All is
better managed by placing cockle or oyster shells in the filter system.
The quantity of shells you need is a bit
of a black art and to say you need "x" bags per 1,000 gallons/litres is a tough
one. My only suggestion to you is that if you suffer big swings in the Ph range,
because of your local conditions and you have had experience of a Ph crash, then
you should consider using more not less than the bench mark. Similarly if you
have never had a crash and your local conditions are stable then you might
consider no shells at all, or at the least something less than the bench mark.
Now what is the bench mark, again there is
no magic to this but would suggest and it is only a suggestion use 5 lbs per
1000 gallons or 1.25 kilos per 1000 litres approximately (tell me if I have the
wrong conversion from imperial to metric)
