Diana I have been doing this for a long time, but a slightly different method.

I use the Rubbermaid Brute garbage cans, with wheels. (I have 3 cans, 20, 32 and 44 gallons)

I put a Knee-Hi nylon stocking full of peat moss in the can (1 knee hi per any size can) and fill with water. Add dechlor.

I start with water the right temperature from the tap, a blend of hot and cold.

I turn on a fountain pump and let it run overnight. Pump is set up in the middle on the bottom and aimed straight up. At first I connected a vinyl tube to the fountain pump outlet and aimed it right into the stocking, but I found that I did not have to do that. Just drifting in the water, the stocking of peat moss does its job just fine. Be very careful that the inlet to the pump is protected. The nylon stocking is very stretchy and can get sucked right into the pump's impeller.

If the house is cool I will drop an aquarium heater into the middle of the water to keep it warm. Or, if I want a blend of prepared water + tap, I will mix it at the last minute with hot tap water.

I can get 3-4 uses out of the peat moss, but it takes longer to brew as the peat moss ages.

Peat moss acts like an ion exchange water softener. It donates H+ to the water and removes Ca++, Mg++ and other things. There is a limit to how low a pH this will make the water, but in peat bogs, where the peat and water are in contact for a lot longer the pH can be as low as 3.5. Peat bogs are a giant version of the same principle: Water trickles in slowly, meets thousands of cubic yards of peat moss then trickles out slowly.

This is a permanent change in the water. However, if there is something in your tank that adds minerals to the water (Limestone, coral or other things) then the water can get harder, pH rise. This is not a problem with the peat treated water, it is something in your tank. If this is happening, the GH or KH rising in the tank, then I would test each item separately to see what is doing that to the water.

I keep peat moss in the filters for a little bit of fine tuning, but the small amount of peat moss in the filter is nowhere near enough to handle the amount of water that I would add for a water change, and I do not want that variation going on in the tank. I want the new water to already be right for the livestock.

Yea... if only kh and gh BOTH didn't contribute to TDS

Would depend on the KH of your tap, as that's what's gonna be buffering the pH change.

acitydweller it sure does!

xenxes This is pretty awesome. Peat moss doesn't leech tannins or anything?

deleted_user_17 Lugged a 125litre bale of peat moss back here yesterday and started experimenting I'm using a bucket, a cut up, upside down 2l water with filter floss stuck in the end and peat. This fits under the taps in the bath. Slow drip.

My tap water
PH - over 7.8
TDS - 270+
KH -10
GH - 16

After slowly running through 3 handfuls of peat

PH - 6.0
TDS - 120
KH - 2
GH - 4

Wow!!

It came out a yellow colour, but after a night in the tank, the water's clear. I added Prime to dechlorinate. The tank filter runs carbon filters then Purigen. I'll add some carbon to the peat filter at some point.

This hopefully means no more driving to buy RO

I'll continue to experiment with timing and equipment to see how far I get the TDS down.

Thanks once again GeToChKn, and everyone else who chipped in to this awesome thread

Tempting however I don't have space for something like that near the tank and Although strog I can't move 40g a water together. Guess I'll figure something out

I'm probably going to try out this method because I doubt I'm going to have an RO unit in the house lol. I have like three cut up 2L pop bottles so I'm probably going to stack them on top of each other to make a tower and make it run through a system of peat, crushed up indian almond leaves, and then through more peat or something along those lines.

When I get my master testing kit someday and build my pop bottle tower, I'll post results and let you guys know how it works out.

That's what I got, a huge bag/bail whatever you want to call it.

A local nursery here has bails. Maybe I'll check out home depot.
