What is better distilled or RO water?

The key is that Ca(NO3)2 is a lot more soluble than calcium phosphate (bone meal). The key is calcium nitrate in general.

Hey... thanks for that piece of info. Another reason to use nitric acid instead of H2PO4 aka phosphoric acid as pH down. So you don't get Ca3(PO4)2, correct?

Too much bs about ro. It is not acidic, my ro ph comes out at 7 ish. Plastic particles? Damage water? Sorry I don't buy any of it. My filter is getting old as my water comes out at .007 ppm. I tried distilled and did not like it. To each his own!

you can't ph real r/o as it has no buffers, if the pressure isn't strong enough you can foul the membrane. I use filtered tap water, i was mostly giving dude shit because he thought he was so smart and told my boy church he was wrong.

What kind of filter, charcoal?? I could get away with just that I bet with my pretty clean (but highly chlorinated) tap water.

The filter really isn't necessary for tap water but it may help. I use a PUR filter at the end of my faucet. They cost like $30 for both the system and a filter over at Bed Bath & Beyond. Typically the filters last about half a year at best.

Unless your living outside of town by yourself, miles from society while using well-water, then chances are that your supplied with chlorinated tap. It's popular. I just fill say a 2gallon container of some tap and let it sit out a day before use. Supposedly the chlorine evaporates within the 24 hours of exposure. That means you want to leave the lid off the container.

In the past, I've used tap water without letting it cure and it works. Probably not a good thing for micro-bacteria though.
