Regenerating RO

[alsbeth]

Hi,does anybody know of a homemade mixture to regenerate R O water,instead of using the commercial stuff[like Kent etc]. Also must the R O water be airated for 24 hrs before use ? cheers Alsbeth

Hi alsbeth,

Here is a recipe I found on the net.
Its was singed from Joe ? (enchanted discus ??) I don’t now.
So if anybody recognizes this recipe pleas fell free to tell so.

R/O + Minerals
If you wish to use 100% RO Water then this is what you add per 20 gallons. I reccomend using a conductivity meter or at the least a hardness test kit.All should be USP Grade
3 grams Calcium Sulfate
1gram Calcium Chloride
1gram Magnesium Sulfate
Calcium Sulfate is gypsom and is available at chemical supply
Calcium Chloride is sea salt-- available at chemical supply or pet store-- get the finely ground type so as to disolve easier
Magnesium Sulfate is merely Epsom Salts and is available just about anywhere
Many people use 1/3 Tap to 2/3 RO. I use 100% Ro especially in winter because of fluctuation of perameters. Obtain a free graph from your Municipal water supplier to see if this is for you.

:bounce2: :bounce2: Hi Alsbeth, Ronald is right, this is Joe's recipe & it is a good one. I've been using it for awhile now, & use a TDS meter to raise the minerals for the fish needs, whether it's breeding pairs or raising babies. Just keep to the 3:1 ratio & you'll be fine. It takes quite a large am't for my 100% r/o water to get to the right level, probably more than the stated am't, but I just depend on the meter to guide me. Sorry to be late, not much sitting time at the pc during my convalescence, but it's gettin' better. lol Dottie ;D ;D

Thank you both,for your replies.cheers Alsbeth

I would just like to clarify. You state that calcium chloride is sea salt. Sodium chloride is in fact sea salt so should it be sodium or calcium chloride. I would assume calcium as you would not want huge amounts of sodium in which case you could not use sea salt.

Ann

To whom are you referring to Ann ?

If you are asking me I would not comment on it since it is not my recipe. If you are asking Joe then please disregard this post.

I personally use R/O Right.

Hi all,
Ann, you are correct in stating that sea salt is Sodium Chloride, but it is NOT just Sodium Chloride. This is the primary "salt" contained in sea water, but it also contains other "salts" as well. HTH

Or do it the easy way and get some Kent RO Right, for those who are lazy like me...lol

I'm using ro vital but having a hard time stablizing pH.
Using all ro my tap has chloramines.
Any suggestions.
Thx Dave

Experimentation with addition of some baking soda would help increase/stabilize the pH/KH. I am not sure how much to add, I would start with a little and see what it takes to get up to a KH of 2-4.

Hi Dave,

To stabilize ( I also use only R/O reconed with R/O right) I have added a small amount of Crushed Coral into the Filter.
Of course Sodium Bicarbonate will work also.

I'm trying the baking soda method, but at 1/4 tsp per 10 gals the pH is about 7.4. Yet still no register on kh. I think to get the kh to 3 or 4 I'd have to add way too much baking soda and raise the pH way too high!
I wonder how the crushed coral would affect the pH and conductivity if you'er trying to breed.

Dave

It has not much (20-30) effect on the conductivity in my Tank. The pH stays stable depending on how much I use. If I use to much it will rise.
But I am not breeding nor did I breed so I would not know that answer regarding breeding.
