I have a 50 gals fish aquarium. After taking a test, it shows low levels of alkalinity (40 ppm) and a ph of 6.8 That shows me that the water is becoming in some way acid? I changed 1/3 of water and the test result is almost the same before and after the water change. The question is : Should I add sodium bicarbonate to fix the water and will this be safe for the fish? If so, how much? Thanks. *Sorry about the spelling, my first language is Spanish.
@@Marlene5018 Depending on your fish and set up, you may want to try using an alkaline buffer. You don't want to make drastic changes, which can shock your fish, but slowly dose and keep testing until you have your preferred range.
Thank You ! .. Dumb question time now .. is the "Buffer " always high ph ( baking soda .. etc. ..) or can it be an acidic buffer = low ph material ( probably not applicable to this situation)
I think this is an excellent question, so much so I started looking around and found this: www.chemguide.co.uk/physical/acidbaseeqia/buffers.html anyone interested should check it. it is a simple explanation, and also has detail. Here are the Cliff notes. Answer: Yes. explanation: A buffer solution has to contain things which will remove any hydrogen ions or hydroxide ions that you might add to it - otherwise the pH will change. The Buffer can be a weak acid and one of its salts, or a weak base and one of its salts. Thanks for asking that question!
That's what he didn't explain, baking soda is used up in the reaction. I gathered from Wikipedia how it reacts with vinegar: Sodium bicarbonate reacts with acetic acid (found in vinegar), producing sodium acetate, water, and carbon dioxide. Sodium acetate is the sodium salt of acetic acid. It is that stuff in those rechargeable hot packs with a clicker inside. Apparently it's a food additive as well. A solution of sodium acetate and acetic acid can act as a buffer to keep a relatively constant pH level.
Thanks for the video but I will be glad if my question is humbly treated... in a situation whereby a water sample is brought to the lab and we did alkalinity test for it but the it doesn't change from to pink. Using titriHappy birthday bro... titrimetric method, what does that implies, and if the water changes to pink what does that also implies
Hi There! If the test doesn’t change to pink, there could be a few things going on that are causing you to not reach your endpoint. 1. Check the expiration dates of all chemicals being used. 2. Have enough drops of the indicator been added? 3. Enough titrant may not have been added, or the titrant strength may need to be adjusted. 4. Your sample size may be too large, so you may not be reaching your endpoint. 5. The pH of your sample could already be outside of the range of the titration. The change to a pink color indicates that you have reached the end of the titration.
Hey John! Great point. Many of our electrodes are temperature compensated with a sensor built in. But if not, it's best to always calibrate before hand to ensure you're getting an accurate reading based off the sample or solution you're testing.
Great video. I'm a new pool owner and now I understand why the pool company is selling me the alkalinity enhancing chemicals.
I am a pool company owner(member of the family)! Never heard it explained so simply. Great demonstration.
Hey Thanks Steven! If you're ever interested in checking out some of our pool gear, here ya go!

Hi Maria. We typically wouldn't recommend adding sodium bicarbonate in aquariums.
Hanna Instruments, Inc. what would you recommend?

@@Lensvoodoo Thanks alot .....
Does the acid react with the baking soda so that once the pH has reached the same level as the first beaker it would be just as sensitive to change?

Glad it was helpful! You are welcome!
Verry clear to understand. Thanks allot!
I never seen how much baking soda you added

Great information thanks
Nice Explainer btw Josh Baumann'
Great video
Great video thank you!
Next time add the water to the vinegar jug.
LoL B-)
Nice video. Very informative. Thanks!
Good video, thanks
Great explanation. Thank you.

Thanks, good stuff!
Why is my pH high and alkalinity low in My hot tub
Very bad Hannah... measuring pH without the temperature probe… pH is temperature dependent and should always be used along side the electrode!
Hey John! Great point. Many of our electrodes are temperature compensated with a sensor built in. But if not, it's best to always calibrate before hand to ensure you're getting an accurate reading based off the sample or solution you're testing.
I don't get it. The science fair baking soda volcano bubbles were nice. Acids and bases. Wheres the explanation and measurement of alkalinity?
