Lowering harness

[dustinpedley]

how do you lower harness in a tank? my tanks hardness is around 300 right now and how can i get it to around 175-200. i want his for my 55 gal and a Reverse Osmosis system isn't in the cards for a while, ive heard drift wood will a little bit but i don't want my water to be stained

CO2 lowers hardness, as well as pH..

But the set-up is mostly for the benefit of plants, and the set-up costs about as much as an R/O system would, so.. :)

You could also try filtering through peat. That will also lower ph and hardness.

Or, you can do a 50% water change and just use distilled water. That, I found will do it too.

Its really hard to remove hardness from water. Thats why people hook up water softeners to their houses and but salt every month because thats about the best way to do it. Adding peat and co2 might help a little bit but your hardness is so high that it probibly wont help much. Doing a water change and adding water that has a low hardness is about the best thing you can do.

yah but buying 20 gals of distilled water every week would hurt the wallet

Well, getting an R/O system may hurt at the start, but is definitely cheaper in the long run..

Peat moss has to be changed out relatively often..
