ro/di buffer

[devilboy]

i would like to start a poll about ro/di water. i was just wondering who buffers their ro/di before you mix up your salt. and if you buffer the ro/di water for daily top offs. since i was reading about Kent Marine Osmo prep. it is suppose to buffer your ro water.

The salt mix has all the buffer you need.

Adding anything to your RO/DI water before making saltwater is just a really bad idea.

also not a good idea when doing top offs. only water leaves. so thats all you shoudl put in IMO.

I was going to say that except for limewater.

i checked my saltwater once to see what the alk was at with using ro/di water since it softens the water but the alk was at 9dkh with the salt im using

Kent must be making a killing... They have a "solution" (lotsa pun) for everything.
They buy picking lime cheap, sell them as kalk at inflated price. Put a few teaspoon of baking powder into RODI, call it RODI buffer and empty our pockets. Scrape some diatom off the glass, call in PhytoPlex. BTW, I dont know these things... I am just speculating...
Ohhh ... I voted 'no'

lol its true u really dont need anything they sell lol
i only use b-ionic currently for any elements and to maintain alk and calcium since my clams and sps use it fast but otther then that i dont add anything not even food for the corals they eat left over juice from the frozen food lol

Anthony Calfo says to buffer your RO/DI before adding salt. I have not seen hard science indicating that it is necessary and there are certainly enough tanks out there that show it is not mandatory.
I do not buffer prior to mixing.

I've heard that before. I find it odd that he would recommend purposely making unbalanced saltwater. I have to disagree with him on this point. I think it would make the ALK too high as the best case and cause precipitation as the worst case.

i add a little buffer for good measure after mixing... when i add my calcium and all my other additives.

Agreed.
