Hi,

I've read that you can filter through peat to reduce pH. How do you actually
do this & what type of peat do you use?

I can only think of the big bags you get at B&Q for your garden & as this is
very fine how would you stop it just being washed into the pond?

Any help gladly received!

Skycatcher dunno if you ever got your answer to the question you had;


There isnt a lot of scientific info on it, but a few things that are well known are these:

The hotter the water while in contact with the peat, the more complete the process. A guy named Mark at a now defunct webpage called MARKSFISH explained how, he would make a 10 to 12 gallon per hour peat filter, out of a bucket. he would put from 3 to 5 inches of poly filter material in the bottom of a bucket and cut a single hole in the bottom, middle;

then he would pour hot tap water, through about a 1/4th to a 1/3 of a 2.2 cubic fot bale of peat, he placed on top;

This would drop 8.something water with a kh of about 12, to 5.5 ph with a kh of about 3.

It's the heat that really makes the process kick off; if you just use a soak of peat, it really, really, takes a WHOLE lot longer. it took me three weeks to bring about 10 gallons of water down by simply soaking about 8 ounces of peat in it; from around 8.5 to 7.


This of course isn't acceptable.


There are people, undergravel filter aficionados, who actually place a layer of peat between layers of gravel, and have their U.G. filter pull the water through that.

I hope this has been some help;
