Aquarium Chemistry Question? Ask the Doctor!

[Randy Holmes-Farley]

Hi Randy,

heres the original german text:
"1ml erhöht die Nickel-Konzentration von 100ml Meerwasser um +2μg/l"

"1ml raises the nickel-concentration of 100Liter (ml is a typo I guess) seawater by 2yg/Liter"

The "ml" - thing should be a typo on eBay.de. The bottles say liter.

Yes, so it is 2 ug/L.

So the bought solution concentration is 200 ug/ml = 200,000 ng/ml.

if you want to dilute that 200,000 ng/ml to 25 ng/ml, you dilute that 1 mL into 200,000/25 = 8000 mL or 8 L.

Hello Randy,

First of all, thank you for your endless contributions to the hobby for the last decades. Then, my question that is a few steps to far for me to comprehend (although it's hard to admit):

I want to replace the Tropic Marin Balling B solution (alkalinity part) for Sodium Hydroxide at night, in the same volume and concentration (in dH/L) for easy adjustment.

What I know is that a Tropic Marin Balling B is a combination of Sodium Carbonate and Sodium Bicarbonate (unknown ratio). 75,6 grams of the Balling B powder per Liter makes a concentration of 2800 dH/L. How many grams of Sodium Hydroxide I have to add to one Liter to make a solution with the same concentration?

Thanks a lot,

~Leo

FWIW, I give a two part recipe that many use Baling Part C with using sodium hydroxide here:

Second New DIY Two Part Recipe with Higher pH Boost

In a previous thread, I posted a true two part DIY recipe: https://www.reef2reef.com/threads/new-diy-two-part-recipes-with-higher-ph-boost.344500/ But some folks may want to just swap the new ingredient into my 2/3 part recipe (as used by BRS, for example). Here's the original recipe link...

www.reef2reef.com

In it, I show this, and if you want it less potent, scale it down:

Add 283 grams of sodium hydroxide to 1 gallon of fresh water. It will get quite warm. Make sure it doesn't soften your container. This solution will contain about 1,900 meq/L of alkalinity (5,300 dKH). BE CAREFUL WITH THIS SOLUTION: IT HAS A pH ABOVE 14. Do not get it in your eyes or on your skin.

You're welcome.

Happy Reefing.

@Randy Holmes-Farley Hi Randy,
Could you please share the recipe for DIY lanthanum chloride solution from ( Lacl3 7H2o ) heptahydrate powder
to reduce PO4 in my tank.

I don't have a DIY recipe, but we can devise one. let me make a separate thread for it:

DIY Lanthanum Dosing

Someone asked for a DIY lanthanum dosing recipe. Be sure you understand that some folks have issues with fish (especially tangs) before embarking on lanthanum dosing. it is also preferable to catch as many of the solids that precipitate out as you can, so dosing before some sort of...

I'm going to lock this thread as it is not really intended for folks to ask questions in this exact thread. Just start a new one in the chemistry forum for any question you have.
