Also- don’t worry if you don’t see the spike straight away. Ambient and tank co2 levels may have something to do with that. If you’re happy with it, just carry on and I think you will eventually see what I did.

Thank you for your quick reply.
I’ve circled in red. There is a sudden rise in pH, then a small dip. When the lights hit peak, you get a photosynthesis driven increase in pH. The unusual bit
Is that sudden rise in pH but as it goes day to day, the pH peak gets even higher and this effect seems to accumulate, which apparently is against scientific principles and part of the debate.
I wouldn’t overly worry about it though.
You can just carry on with normal balling or other method to keep your alk and calcium dosed.
A higher pH is more desirable for tank health. And bolus dosing seems to provide a higher overall pH than standard balling dosing….. everything. Else remains the same, so it seems like a good add on for reef tank health.
There are other ways to get high tank pH like Kalkwasser dosing, but this can be hazardous if not researched and done carefully, but can be a very successful technique.
There are other dosing methods too. All of these methods work. Some reeders like one method, others like another.
I wonder if in your graph the pH boost is very small as you do have a little rise at the start. It may be that your bolus dose is just small. I did see a gradual increase in tank pH levels over a few weeks. And the same happened each time I went back to bolus. You might see the same as you carry on.
I found in the podcast at 49:10 where Doug did say to be patient as you may or may not get the immediate pH spike when you 1st start the bolus method.
As for my alk level, I have found my daily alk consumption to be 0.8 dkh. right now my DKH sits at around 7.3.
I believe I may have more room to bump up my initial bolus still. I need to remeasure my alk level over this weekend before bumping it up.
How big is your tank when you dose your 600ml of KH?
My 120% Solus of white light turns on pretty immediately at 7:00 (about 30min after the initial bolus) and then goes back down to 100% at 9:00 a.m.
One thing I would note, is that your pH is quite low, so it would be worth looking at things like ventilating the room the tank is in. Having a big skimmer with airline from outside. Co2 scrubber, maybe an algae bed. Those things will help with boosting your pH by reducing your co2 levels.
I have a feeling that bolus will have a stronger effect on tanks where the ambient co2 in the air is lower.

My tank is very large. It measures 8ftx 8ftx 2ft and I have another tank connected which is 5ftx5ftx 15”
They are still Only lightly stocked though.
Based on my old tank, which was similar in size, when it was at its peak, I’d probably be dosing an estimated 4L of alk solution per day- based on the calcium reactor activity that I went through. I swapped to a calcium reactor when I was dosing around 1.5L of alk per day. And I added an extra media chamber and 2 large peri pumps to it, which trebled its output.
This is my old tank.

I'm looking at putting the Abyzz on my tank too... What's your verdict on them? Also what do you have as heaters for your tank?

Hi, I’m about to build a new SPS system. The tank will be 8ftx 8ftx 27”. My last tank measured 6ft x 8ft x 3ft. I had a tank thread on Reef Central at the time. Here’s a photo of the old tank….

Thank you for pointing out the lower pH.
Typically my pH hoovers around 8 at it's low. I have been feeding corals with the bacterial concoction quite a bit this week.
I have an oversized skimmer for CO2 circulation and a CO2 monitor in my cabinet. My CO2 levels in the cabinet hardly goes above the 650ppm level.
I do have a recirculating CO2 scrubber, but wanted to try doing the bolus method without the CO2 scrubber as was mentioned in the podcast.
Hello @Mo. Can you help me understand what I am not seeing in my tank's pH chart and possibly your pH chart as well compared to what Doug Dorrat's example chart showed in Frag Garage's podcast at 40 minute 25 second mark?
He explained that when the bolus 1st gets injected, he gets an increase right away from 8.15 to about 8.25 pH.
My tank size is about 150 Litres (40 gallon)
Here is my initial pH before my 60ml of Fauna Marin Balling KH is injected at 6:30 a.m. with pH a 7.86.
In my case, I have not yet seen an increase in a jump in pH from direct injection of the bolus right away. Here is another shot of my pH at 6:50 a.m.
pH only shot up to 7.9
I started using Fauna Marin Bolus method earlier this week when I finished using up my ESV B-Ionic two part.
My pH is low since I fed Alan Vo's bacteria concoction to the tank about two days ago.
Maybe I am not injecting a big enough bolus into the tank or could the pH still be suppressed from my feeding?
That is why I would like to ask if you have an immediate increase in pH when you 1st inject your bolus into your tank?
Any insight is greatly appreciated!
Just looked at the video you posted as well.
Look at 42:20 onwards- Claude says it goes against what the textbooks say and he wasn’t quite sure why it happens…..which confirms what Randy was saying too.
Cheers
Mo
I think it will Work for you then. Just be patient with it…..and do one thing at a time, don’t take the scrubber off yet…
Not sure about the concoction- you might save it for when everything is stable?
I think the concoction is based on what Thomas Pohl used to advocate with his coral feeding methods using his blue bottles…..
Cheers
Mo
I envy the size of your tanks! Has the price of electricity gone down somewhat now?My tank is very large. It measures 8ftx 8ftx 2ft and I have another tank connected which is 5ftx5ftx 15”

I agree, I have stopped feeding now and will control just the one variable with the bolus to see how long it will take to raise my pH.
As an aside: There is a new video on bolus coming out 10 days.

You can fix the lightly stocked bit quickly. Add Biota's Lyretail Damsels
I added 11 and they are amazing sauce. Bring the reef to life without the Chromis fight clubs.Teasing of course (on you adding them).

Wait? And you do understand 'it' so your presence here is warranted and the rest of us should just need to understand.
Perfect.
Now that we have that settled. Please do explain exactly how this works, along with the science and proof of the "broken buffer" concept and various other claims presented in the videos to support the benefits and magic of "Bolus Dosing" and why his product is the only product that can or should be used.
You can't.
90% of us are here following along and/or participating in pointing out inaccuracies or attempting to separate truth from fiction.
Stop speed reading. Slow down and read again and you may see where I’m coming from even though I repeated it many times, you still seem to be missing the point…..
Which I’m not going to point out again just because you can’t be bothered to read the thread properly or look at the explanations that have been put forward in multiple streams by other people.
No!But you do get the point
This doesn’t need that level of repeatability to ensure it’s not error.
It just need common sense and multiple people to try it out and get repeatability that way.
I have already posted that I have switched back and forth several times and got the same results over several
Months.
But you will Always find a reason that this is due or error or tolerances in the equipment or what not- when you rely on consumer level test kits yourself and never question that……
It’s a joke….

Can you post similar graphs from when you were dosing the same product spread out?
