Today we're sharing a whole new perspective on your reef tank's Alkalinity. If you want to know the science behind what's really happening in your tank when it comes to pH and alkalinity, this episode is for you! Ryan shares the relationship between pH, carbonic acid, bicarbonate and carbonate on a whole deeper level so you can stop leaving 70% or more coral growth on the table.

If you're the type of reefer who loves the deep down science behind what's happening in your reef tank, then this is your episode! This level of Alkalinity science will not only leave you more informed, but will also help you find that 50%-70% more coral growth you've likely been leaving on the table.

Another GREAT video! My tank is now at the 6 month mark. Have been keeping my dkh at 8.5 for 2 months now from orginally 7 ( what Tropic Marin Pro kept it at) and my coral growth has really taken off after raising the dkh. Im using Seachem reef builder to raise and it has no imidiate impact on PH. It does keep my PH at 8.3 and this combination seems to work very well.

@homegrownreefer 3 года назад

i keep my dkh at 9 also. since my kids are home schooling, the excess co2 has made my alkalinity consumption increase. i had to increase my two part! the tank went from 9dkh to 7.2- 7.6. i could be wrong in the reason why my consumption went up alot! great videos, keep them coming!!👍

@BRStv 3 года назад

Interesting. Usually increased CO2 would lead to lower pH and lower alk consumption.

@captivebredcanada 3 года назад

You make it sound so tempting to raise my alk but I am very comfortable in the 7.5 - 7.7dkh range. Slightly elevated and I check my dosing equipment frequently enough that I'm not too worried about forgetting about it or having a technical issue. I've also used the same test kits in the same way for many many years so even if I'm doing it wrong I'm getting the same results year in year out. I also carbon dose which I've always been told is best in a lower alkalinity environment. Still this video has got me considering trying a higher dkh in one of my satellite tanks. I do know my PH doesn't usually peak much above 8.1 maybe 8.2 and does drop to 7.8 at night.

...but what REALLY blew me away about this video is the seriously strong parallel between reef water pH needs and the water (not blood or urine) our human pH needs. When one eats a lot of bread, meat and potatoes etc (alkaline foods) it forces your system to turn acidic. When one eats more neutral and acidic foods, fruits, vinegar's etc, it forces your body into a more alkaline state, which cancers cannot grow in an alkaline environment. I have always said, and told others, "If it has a commercial DON'T eat/drink it!!" When is the last time you saw a commercial for roasted chicken and carrots? NOT from a restaurant commercial, from the growers?...NEVER, yet Coca-cola and Doritos are every other commercial.

Increase dosing slowly over the next few days or weeks depending on your current dosing schedule until you get to your target

We usually suggest to not raise alkalinity by more than 1 dKH in a 24 hour period. Since this isn't an emergency situation, raising this slowly over a couple of days would be ideal.

@williammueller149 3 года назад

I fight low pH and Alkalinity everyday. I dose Red Sea KH/Alkalinity Part B 50 mL everyday. The KH goes to 7 to 8 and pH rises to 8.3 for an hour or two and then falls back to 7.8 by the next morning. The KH falls back to around 5.8. If CO2 is my problem, could I just add an Ozone generator to my skimmer and eliminate the fluctuation? I would also benefit from the ozone killing any harmful bacteria.

@thesupercheerio 2 года назад

Does it mean anything if I'm dosing an equal amount of alkalinity solution through out the day, and my alk actually rises through out the day and drops at night? This is shown in my trident there testing four times a day, and I double check it's reading with my Hannah a few times a week to make sure it's accurate and it is.

@BRStv 2 года назад

Normally you'd see a drop during the day when the corals are consuming it, then an increase over night when the lights are out. Of course, it all depends on how much you're dosing and when. As long as you're not seeing it trending up or down, I wouldn't worry about a day/night alkalinity swing too much. If it really bothers you, you could adjust how many times per day you dose and when you add those doses to the tank.

There are many factors at play, so while a high pH is abnormal with low alkalinity, it's not impossible. Sounds like dosing some sodium bicarbonate to get your alk up would be the best choice for you as it doesn't raise pH like Soda Ash does.

How do you lower the alk at 13 ph is 8.2

@BRStv 3 года назад

If you want to lower your tank's alkalinity, you'll either need to stop dosing and let the corals consume it over time, or do some water changes with a lower alkalinity salt mix. We suggest picking a salt mix that more closely matches your alkalinity goal. For example, if your target dKH is 9.0, something like HW Reefer salt mix would be a great choice. If you're trying to keep alkalinity elevated around 10-12 dKH, then Red Sea Coral Pro or Instant ocean would be worth considering.

@BRStv 3 года назад

Before adding more corals, try to get your alkalinity down to at least 12 dKH. We usually suggest 9 dKH as that's a good middle ground to account for potential testing procedure or test kit issues. If you want to get down to 9 dKH, you may have to consider the alkalinity of your salt mix. For example, salts like Red Sea Coral Pro and Instant Ocean tend to mix up with a high alkalinity.

@Gro2healthheirlooms 3 года назад

Will a refugium with chaedo algae be enough for a soft coral reef tank and help maintain the 8 pH?

All depends on the lighting you're using for the refugium and size of the refugium in comparison to your display. Definitely possible if implemented correctly.

@BRStv 2 года назад

If you need to make an alkalinity adjustment, we recommend doing that with Sodium Bicarbonate, then use the Soda Ash to maintain the alk level there. Of course, you could always consider dosing a combo of both sodium bicarbonate and Soda Ash if your pH is too high. That may take a little trial and error to get the combo exactly right for your system.

Im trying to lower my alkaline! Its so high! I tried everything (that i know)! Im over 14.0 dkh😭. My lps gave me Rowa phos so i bought a separate canister filter and added 500g into it for the last week! My tank is 180 gallons mix reef! Mostly soft corals. What else can i do? Also i did 3 separate 80 gallon water changes in the last 2 weeks! Still nothing!

To lower alkalinity, you have two main options. Option one is to stop dosing any alkalinity supplements, if you haven't already, and wait for the corals to consume the alkalinity naturally over time. This could take a while or be very quick depending on how many and how large your corals are. Option 2 is to do a water change with saltwater lower in alkalinity levels. Since water changes aren't helping, my guess is that your salt mix is also high in alk. Salts like Reef Crystals, Instant Ocean, and Red Sea Coral Pro all have pretty high alkalinity. Consider using Tropic Marin Pro Reef, Red Sea Blue Bucket, Brightwell Neomarine, or HW Reefer salts just to name a few with alk in the 7-9 dKH range.

@@BRStv yes i stopped everything on dosing! I use Instant Reef Crystals! Im going to order a new salt today....i hope this works!👍🤞

@@BRStv Thank you very much for your help! You were right its the salt i was using! All my lfs couldn't figure it out! I placed an order with you and im excited to be getting my order from you guys soon! Thank you!

Also shows why reefs in the wild must be struggling with all the increasing CO2 in the atmosphere going from 280ppm to over 415ppm now with a natural KH of 7 this must be dangerous for wild corals.

Your definition of alkalinity is improper in chemistry. Just a heads up.

@bgoldb21 3 года назад

Do you increase the alkalinity of Tropic Marin pro salt before performing water changes? The salt mix is around 7dkh and will obviously bring the dkh down with water changes.

@BRStv 3 года назад

a 10% change will bring it down about 0.2 DKH . You can correct for that in the salt bin or your tank. If your water changes are done regularly its probably best done by upping your daily dose a few ml to compensate.
