  • Conditioning RO water for South American Cichlid tank (lightly planted)

    I have been looking at the different products and I'm confused as to which products are best for my application and how best to apply them.

    First question, when conditioning RO water for SA Cichlids, will the Seachem SA Cichlid salt take the place of Equilibrium?

    Second question, what is the proper sequence of steps when conditioning RO water?

    Example:
    Step 1: Add Alkaline buffer until desired KH is reached
    Step 2: Add Acid buffer to bring pH to target
    Step 3: Add SA Salt or Equilibrium to bring GH to target

    Third question, since the < 20PPM RO water is a known variable, can you provide a baseline for product amounts (in grams please)?
    I understand there are many variables and one size does not fit all but please be as specific as possible.
    (assume mixing 5 US gallons at a time)

    If I am completely in left field, please provide guidance

    My apologies if this is basic knowledge, and thanks in advance.

    My buffers and SA salt arrived via post a while ago so I gave my logic a try...

    Starting point: 5 gal (appox) of RO @ 2-3ppm

    First I added 1.5gram of Alkaline Buffer
    Results: 42 ppm, 4dKH, 8.1pH

    Then I added 0.7grams of Acid Buffer
    Results: 70 ppm, 6.9pH

    Finally, I added 0.5 gram of SA Cichlid Salt
    Results: 94ppm, 6.9pH and I believe 4 or 5 dGH (I find it difficult to differentiate the color change but that would seem inline with my PPM meter)

    It seems right, but please advise...

    Thanks in advance,
    B

      Hi there! Let's go through this from the beginning, for the sake of clarity. SA Cichlid Salt is intended to be a GH supplement just like Equilibrium, but it does have a different mineral composition. You don't need to use both, but it may be necessary to chose between them depending on whether you want the mineral environment to best favor the plants (Equilibrium) or best favor the fish (SA Cichlid Salt). Neither will cause damage to fish or plants, but you'll get your best plant results with Equilibrium and your best fish results with SA Cichlid Salt.

      What you've described sounds like a pretty good sequence, but you'll want to calculate out the amount of Acid and Alkaline Buffer that you want before adding it to the water - often, the water chemistry does not respond quickly enough to the addition of buffers to be able to accurately dose A&A Buffers by guess-and-check.

      What do you mean by a baseline? Are you wanting to know the effect that each of these products will have on TDS, or are you wanting to know the specific amounts of these products that we recommend to reach a given water chemistry? The changes in water chemistry you are seeing seem like what we would expect, but I need to know what results you want out of the products before I can tell you what our recommendations are to reach those results.

      Thanks!

        RT,

        Thank you for your assistance :-)

        I understand on the SA Cichlid Salt vs. Equilibrium.... that's simple enough.

        By "Baseline" I assumed (LOL) since quality RO water by definition is a known variable that product amounts would be pretty standard depending on desired target values.
        Most of the charts I'd found online simply refer to the ratio of Acid Buffer to Alkaline.

        Based on what I want to do, I think my ideal target values would be:

        pH 6.9-7.0
        dKH 5
        dGH 6

        I want soft but I also want stable, so looking for a happy medium. I'm open to any advice you may have.

        I've had Bolivian Rams for quite a few years but they are nearly bullet proof. I'd like to try some of the other ram species.
        My tank is low light, and plants are limited to Anubias ssp, Crypts, and Java Fern.

        My TDS meter is mainly used for calculating the rejection ratio of my RO membrane. It did seem like a good, second opinion qualitative guide though when doing my "guess and check"




        One more question please.

        Can I use this water for weekly water changes in my established aquarium and as a result slowly bring the tank's numbers to the new target range?

        I appreciate the guidance and the great product line.

          Hi there!

          To get those parameters, here's what we'd recommend per every 5 gallons of RO:

          3.1 g Alkaline Buffer
          1.6 g Acid Buffer
          8 g Equilibrium

          And you can definitely use this with every water change! That's the way we normally recommend customers make changes to their water parameters.

          Thanks!

            Wow, there is a significant difference between those numbers and my preliminary "guess and check" values
            After reading your recommendation, I ordered the Equilibrium... (rural area, no local sources)

            Since I already have the SA Cichlid salt, could I use it as a back up?
            (e.g., waiting on Equilibrium to arrive, etc.)
            If so, what are the measurements with it?


            You've been a big help, Thanks!

              You can indeed! The amount of American Cichlid Salt you'll need is around 1.25 g, but as I mentioned this is going to be heavily weighted in favor of the fish, not the plants.

                I understand and it will only be used as a secondary option to Equilibrium.
