It says nothing on whether pH moves are dangerous or not, it simply states that low KH does not lead to pH crashes. To that, I said that pH is indeed volatile. Nothing more.I suspect that it’s a hang over from the now debunked belief that low KH could lead to pH crashes.
I’ve changed my view in the middle of a post 😂 … as I think through a problem.Herein lies the problem. What we say on the web lives forever.
I have said this many times over the years.
Whatever I said I believed to be true at the time I said it.
And I know Tom Barr would say the same thing.
Yes CSM+B uses EDTA and is better for very low pH tanks. DTPA is a better choice when pH is higher. Now was that your problem? Who knows?@GreggZ thank you very much for the detail about your pH readings. I just read the article about tanks with low pH values (2HrAquarist) and I now think I may know what may have gone wrong way back when I started (and eventually stopped) using EI. Initially my CO2 never reached a point where it the pH was below 6.4 and I suspect that my micros may not have been used optimally as I am using CSM+B, where the Iron chelate works optimally below or around a pH of 6. Is my reading around this correct?
Additionally, I always assumed that if my drop checker was slightly yellow my plants would suffer tremendously. After reading the above article this is clearly not necessarily the case. In short, thanks for all the insight.
I think? Clive's suggestion of 3 ~ 4kh was once mentioned by him in regards to stability when injecting and monitoring Co2 (ph readings) I could of course be completely wrong on this.
Truth is and Clive would definitely say take no notice of kh, work with what you have, do whatever is the easiest, the plants won't care.
Also as Greggz points out, there are lots of beautiful tanks out there that run 0 ~ 1 KH.
Since we are in a new era, we decided to removed the dKH values from the pre-set EI regimes in the latest update.I suspect that it’s a hang over from the now debunked belief that low KH could lead to pH crashes.
Just choose 7% Fe and your done doneApologies for resurrecting this thread again, but for some reason I can't get hold of the CSM+B micros anymore. I will have to order from abroad or come up with an alternative. I can get the GLA Micromix (EDTA 42%+DTPA 14%) in the US. I am reluctant as I can't see on rotalabutterfly where I would select this as my micro mixture. Any suggestions that might not require so much expense?
It is actually in the IFC Calculator so you can make all the calculations you want there . But looking at the backend now I noticed some slight changes in the composition compared to the website. Some of these companies like to modify their recipes for no apparent reason other than screwing with the IFC calculator 😂. GLA is a company that never answered either of my emails, sms or support question. Poor service indeed, but their product is probably just fine.I can get the GLA Micromix (EDTA 42%+DTPA 14%) in the US.
