@@scotty2salty327 thanks! He was a really fun guest! Great corals too

I'm with you. I'm using Reef Crystals now for 27 years. I actually switched to the REGULAR Instant Ocean. They started putting less Magnesium in Reef Crystals, did you notice? I now have to dose it and I never had to before.

Also Kenny Lin's sump with it's 4+" of detritus! haha

Leonardos too right?

seemed fine when I tried?

Totally agree, that display is on fire!

Oh you know I believe in Bolus DD.. The comment was simply that perhaps people who were running their par a bit conservatively before the method saw more of an immediate impact..?

@@fraggarage5922 Yes definitely. For some they discover that their lights were set up completely incorrectly. The great one is setting them up really high thinking the spread is really good.. you could do it with a G4 Radion but not the new stuff that has much improved spread.

best of luck! happy to help haha

You're welcome, thanks for the feedback and kind words!

I think that's the brand that uses hydroxides, right?

@@fraggarage5922 not sure sorry 😞 is that bad for the system 🤷🏻‍♂in my 100 gallon mixed reef I struggle with some sps basing out , PC rainbow & Fox flame fine .but others not so 😢 Be great for you to do video on care of corals 🙏😁

Nice! What system are you on right now for major elements etc?

No, I am not a chemist, I don't need to be, I am a coral farmer. Also, I am not guessing.. I have worked with corals for many years in a commercial farm and have experienced more than most. I do have evidence, plenty of it. I have consulted on more than 2000 ICPs tests and see the problems on a weekly basis, the Fauna Lab has the biggest body of ICP data with more than 200,000 tests. We also have plenty of cited , peer reviewed research that is used to confirm our conclusions, we spend a lot of time on this. Yes you can run a great system on soda ash (and kalk) but I am trying to make people aware there are side effects that do eventually catch up with you. Kalk is a great example.. with a calcium reactor it works fine as long as it is used in moderation, dose it alongside soda ash and expect trouble later on. Still think we are guessing?

@@fragfarmltd It is clear that you have a lot of experience and access to a tremendous amount of quality information and I think that what you shared is valuable. I think the part we don't understand is the mechanism by which "old tank syndrome" or tank failure happens from using Kalkwasser or Soda ash. You would need to be a chemist to explain such a process, and we simply don't have that information. When you look at aquarists like Reef Bum who is exceptional Acropora keeper and who uses Kalkwasser, or for that Matter Adam from Frag Garag as well it clear that the theoretical understanding we have of the topic isn't a rule and therefore at best a theory. Does that make sence?

@@davbenav No, sorry, I don't accept this. Just because I chose not to pursue an academic path into chemistry does not mean that you can not learn the subject, this is a ludicrous notion. I am educated to an advanced level in chemistry, I chose not to get a degree in this subject because I could not see the point. Most of the people I have worked with in my career, the real experts, often do not have the academic qualifications in their field. You are also making the assumption that a qualification in chemistry somehow gives a full understanding of what is going on in a reef tank, this is simply not true.. in fact its nonsense, there are a few reefers with high qualifications in chemistry who are masquerading as reefing experts.. those who actually work in farms see right through them because they can only give you theories from text books for how the chemistry works in a test tube in a laboratory, reef tanks quite often don't work the way you expect because of the interactions of the plethora of compounds in the water. When it comes to explanations of 'old tank syndrome' we have decades of experience where we have seen the conditions where it happens and we have the ICPs to reinforce our understanding, this is not just a theoretical explanation. If you listen to what I am saying in the podcast we have extremely good evidence that explains how old tank syndrome comes about and how the dosing of high pH solutions can eventually lead to the old tank syndrome outcome. Claude (Fauna Marin) and I both have personal experience of this in our own farms.

@@fragfarmltd Can you show us evidence of your theory on old tank syndrome? Are we supposed to just take your word on it? If you have good evidence then lets see it in writing, clearly and supported by peer reviewed data, otherwise these are just anecdotal evidence.

@fragfarmltd Experience is valuable, but making up science is not. The issue is that both you here, and Claude (very) often present opinions and observations as established facts or scientific discoveries when they’re largely assumptions based on your own observations, biased or not. For example, in this video, you reference corals as being "immune" and offer mechanisms that seem like pure conjecture. The conjecture is fine, but offering it as settled fact is not. I’m open to following advice based on experience and an honest "we’re not sure, but this seems beneficial." But don’t blow smoke up peoples behinds and create unsupported scientific explanations that suggest it’s some kind of magic a trained chemist or biologist wouldn’t understand. Worse, don't use that crap as the foundation to peddle products and content monetization.

@@hoandinh8891 that’s fair! I’d definitely like to get Dong on at some point! Next episode is Golden State Corals and then probably Golden Basket :)

It's definitely a good question. I personally think the growth happens towards the second half of the photoperiod, but I will dig for more information or find a guest who knows for sure.

@@fraggarage5922probably the same way that plants do. They absorb the nutrients and sunlight during the day and it’s when the plant can “rest” they can actually use the products of photosynthesis to produce new growth. I think coral are like a hybrid between plants and animals considering their relationship with the Dino’s inside them. Same thing with skincare. I use all my products before I go to bed but our bodies heal and fix issues when we are actually resting. I’d love to hear the science behind it though so good luck finding a guest! 😝. Keep up the awesome work

@@davidturner3461 thanks! Those are mine.. didn’t have any time to get anything from Doug..

Yes, so did I. Then I started to understand more about the side effects. If you regularly water change then you are going to be diluting the nasties.

Thanks! just filter socks, but I'm trying a roller on the new system soon..
