Reef Chemistry: Alkalinity Level Testing

[@lunterloaf6655]

I’m really enjoying your narration and superb cinematography - thanks

[@Leigh33]

Again, thanks for the in depth explanation. I'm still some way from truly understanding it all but im getting there.

[@grandreefer9570]

And why i haven't seen before. Today i've checked my KH, Calcium & magnesium via salifert and found out that they are very low. So now i realize that i didn't consider the amount of liquid that hold this pink plaatic tip 🤦‍♂️.

[@rhondadunn4228]

I have a problem with my all dropping at night. I don’t know the correct way to fix it so I try to correct it every morning. Should I dose soda ash at night?

[@johnmayes6517]

How do I get my alkalinity down I did 50% water change an it's still high. I'm totally new to this any help is welcome

[@silkjc]

You do awesome videos mate, but I really wish you'd do some more 'advanced' stuff. Your knowledge is very valuable, and you have a lot more of it than more people. Some of these basic chemistry topics already have a lot of resources to learn from...I think you can offer a unique source of advanced information though :D Great vids though...

[@rhondadunn4228]

My test says my all is 15… is that too high? If so what should I do?

[@ScottM]

Great video Than and thank you for this series.

[@rainingmackenzie]

Mt T !!! You are on a roll ....Keep it coming .... SUPERBBBBBB Video as usual with is a norm from you now !!!

[@gabemoreno9317]

Have you ever tried the Hanna digital tester colorimeter? It works wonders for me. It helps lessen user error and gives you a straight number.

[@lazerith840]

My test kit came with pictures that show your supposed to draw fluid without tip, put tip on, inject fluid back into container, then redraw and you will have fluid at the 9.6 mark or 9.5 with tip on. I don’t know if this is correct and they really need to clarify how to properly use the test in my opinion. Edit: I just tested using the method shown in video, had same results. I guess the pictures I mentioned just explain a different way of coming to same measurements. I guess this is a way to double check if your testing right.

[@eastnjman368]

Great explanations

[@gallixymike1530]

You had 5.5 left in the syringe so are you supposed to measure amount used ? 4.5 ? You measured 5.5 in the video. Am I wrong ?

[@space_guy_04]

amount left

[@marcosherrera675]

Can't keep alkalinity and magnesium up in this 65 gallon mostly lps tank. Please advise a good supplement I can manually dose myself each day

[@bobtailvw22]

I would love to hear your thoughts on ocean acidification in the wild

[@ZachShannon]

That acan bowerbanki is so nice!

[@jbhuse]

Great video, do you have a video that talks about how you deal with Nitrates and Phosphates? Do you carbon dos or use GFO?

[@DJ_LittlePea]

Thank you for explaining all this for us is so much listen to you explain it than troll all those awful forums 🤗🤗

[@MACNTOSFAM]

when you say “acid” i’m assuming these are hydrogen ions?

[@reaganho4602]

Try use Aquaforest component 1+2+3+ to buff every elements equally. My Magnesium increase from 1340-1410, calcium 380-420 and alk from 8.0-9.3 over 4 day of dosing little amount

[@billyhenry4488]

Wow

[@Willyoustandintheend]

What do you think of the Hanna testers I know they can be $$ but if it makes things easier to test and read then most likely I would test more. For me if it is easy and works I would test more frequently

[@hediki]

What acan is that at 5:08 than ? I have it and I just what to know what it is .

[@Chris-zi9bb]

I use the Neptune Apex Trident system to monitor my Alkalinity, Calcium & Magnesium. I manually test Phosphate daily.

[@LaxMan2k]

Than, I'm having a problem with my acanthastrea lordhowensis frag. The tissue is receding and exposing skeleton. I have been asking around on the local reef forums and they all have said that an ALK level above 9 can be dangerous for these corals. My alkalinity is at 10.4 Dkh and I'm doing water changes with Red Sea coral Pro salt which has a default ALK of 11 Dkh. My question is what would you recommend doing to lower my alkalinity levels? Everything I have seen is how to raise ALK or keep it stable. I understand you are busy but any help is greatly appreciated!

[@DeeFromBrooklyn]

chemistry is such a tricky balance is a wonder how we managed before all the science became clear. .I found that a drop in ALK usually reflects a drop in Mg

[@JanetDiaz6152]

I believe if you alk is low , your cal is low..

[@HNiCDuke]

Janet Diaz no its actually the opposite

[@JanetDiaz6152]

ohh, ok .

[@ironman20725]

Great videos! I actually just bought these same test!

[@addictivereefkeeping]

Once again great video! Keep it up!

[@chriswiebler6151]

thats a bad ass bowerbanki

[@Forgetii]

Random question here, but what is the name of the coral shown at the end of the video at time stamp 5:59?

[@tidalgardens]

It's an Acan. Probably an echinata.

[@twolovingdogs6615]

great info

[@Willyoustandintheend]

Also do you use ppm or DKH what's the better of the two and why use one over the other.

[@mikemcnamee6030]

Noveske O2369 do you use mph or km/h when driving? What is better? Doesn’t matter what you measure it in. 95% of hobbyists use dkh. Probably because it’s a low numerical value with enough precision for our uses in dosing/monitoring coral growth.

[@jackiekearney]

Thanks for sharing.

[@Albertoamigon]

new vid. yay

[@Brgyourownbombs]

what do you do about high alk? I'm currently at 10.9 and trying to aim for 9.

[@ironman20725]

Brgyourownbombs I was told to check mag levels and don't dose anything till mag levels are around 1350

[@Brgyourownbombs]

brian tatgenhorst my mag hovers around 1350 +/- 25

[@ironman20725]

Brgyourownbombs brs just put a video on this subject

[@adamsalinas82]

Finally make more

[@micahlobin9732]

Than natural seawater is 7 dkh

[@tidalgardens]

You are right. It's higher in some places, but closer to 7 than 8 or 9.

[@lildeena1]

I went back to API test kits because I was conflicted about how and where to draw the fluid to. Also different kits fluids fill the syringe differently. I am open to testing with these types of kits armed with this detailed info. Thanks!

[@deanfielding4411]

In a sense it is irrelevant where the fluid goes to, the important bit is that the rubber piston moved from the zero mark to the 1ml mark, as this means the displacement is precisely 1ml, so that you know that when the top of the piston is on the 1.0ml mark, you can refer back to the precisely how much has been dispensed. I hope that makes sense. I’ve seen loads of people get confused and wrongly worry about where the liquid is.

[@Gyatt660]

thanks Than for your videos helping us simpletons like me understand these issues. I'm quite new to reefing and I need all the help I can get. God bless

[@googIereallysucks]

Natural seawater dkh is not 8 or 9, it's closer to 7.

[@tidalgardens]

You are right. It's higher in some places, but closer to 7 than 8 or 9.

[@googIereallysucks]

Tidal Gardens Inc. I was actually watching other one of your videos when I got the notice you responded to this one, lol. Quick question, do you feel it is needed to keep detectable no3 and po4 when you feel the corals? How are you supplying nutrition to your tanks? Thanks, love your videos!

[@TerraReef]

I believe Than talked about this in another video to a larger extent, but in part he has fish in his system which he feeds. The fish waste can contribute to coral feeding.
