Great conversation, as usual!!
I think that Mr Dorrat speaks with absolutes about anecdotal information making him sound like he is an expert chemist when in reality he is guessing like the rest of us 😂. The reality is that people run great systems with Kalk and Soda ash.

Joe Yaiullo not only doses kalk, he doses slurry. Long Island Aquarium has the most incredible exhibit anywhere, it rivals nature. Can't argue his success using kalk.

Adam - I love your podcast and it is my favorite source of reefing information. I think it would be safe to say that a large portion of the episodes / advice on your channel is specifically discussing systems that are growing corals to sell. Generally, this seems like the best advice for everyone to follow as these are the people making money off growing corals. But I do wonder how much of the advice would change if it was aimed at the hobbyist trying to keep a nice Display Tank in their house. Possibly it’s an episode idea: comparing and contrasting advice for the home DT vs advice for the coral growing business.

New drop!! Behind the reef is my favorite reefing podcast that helps me get through my work day lol.

Happy Friday!

Fascinating content,  have we got it wrong all these years, re alk stability and dosing, or is this an incremental step forward in our understanding.
Well done thanks guys.

Finally a new drop !! Lol. You should be doing these twice a week. Nice work Adam!

👍👍👍👍👍👍👍

I’ve been doing the bolus method for 20 years
I dump my bicarbonate in the morning before I leave for the day it is between 1 and 3 dkh per day I guess the old way is the new way

I could listen to Doug all day. Great episode!!!

Stunning corals in the background video, just wondering who’s they are, frag farm?

Sometimes a fan on top of the tank makes the water evaporate too fast. The Auto top off is adding too much fresh water and the salinity goes down.

I've ran cheato for 15 years. I find it the most reliable way to export nutrients and raise ph at night.

If corals do their deposition at night, why is my alk consumption three times higher during the day?

But what is the ideal (or better)nitrate reducing method then other than water changes ? (for those who need additional help and water changes are not enough)
because Algae reactor or refugium are bad because of toxins and carbon dosing of any other similar method reduces pH and adding Kalk to combat that isn't ideal, then what is the better way to approach maintain low level of nitrate, phosphate and also keep other parameters in healthy range ?

Im still waiting for an explaination to the problem that Fauna Marins Alk dosing instructions are configured to carbonate, not bicarbonate. This leads folk into thinking they are dosing a lot more Alk than they actually are, which is not good in quite a few ways.

So the £65 ICP MS tests on the market actually use OES for the majority of the results? The £35 extra is just for a select few minor trace element results in a greater resolution. Interesting! Had never seen this mentioned before!

Great episode. Would be nice to hear how bolus compares to DDs Phplus system

Is there a video link on the method use of dosing? Bolus method thanks.

Very confusing.  He never gets to the solution.  Seems we just need to lower the level of H+ in the water versus inside the coral making it easy to eject the H+ from the coral.   How do we do that simply?
