I'm in the process of using eheim torf pellets which are peat pellets in attempts to lower my pH. I have a 20gal tank, I put about 1/2 the pellets into the included mesh bag and put it as the last thing in my Rena cannister filter on the 20 long.
The first few days it dropped from about 7.6 to 7, gH dropped from 5 to 3. So far it has steady there, but its only been a few days. They don't really tint the water much and are a lot easier to work with then just normal loose peat. From others that I've read, they should drop the pH down to 6.5 or so, and the gH should stay around 3 after they start working and should last a few months at least if not longer. I would assume it will take a week or two to lower to the 6.5 range if its going to get that low, which is fine because a gradual decrease is better for the critters in the tank. I was going to go with regular peat, and maybe once I understand how it works or I have some time to setup a bucket and a HOB filter and test how fast it lowers it but I don't want to experiment with my current tank. I think the pellets are probably made to work more stable than normal peat. Of course if you want the more tannin colored water, you may want to use regular peat. If I was setting up a tank and didn't have anything in it, I would experiment with a bag of spaghum peat moss and my tank param's but not while its full of plants, tetras, dwarf frogs and a bunch of different kinds of shrimp.
