Thanks guys. And Dan Ive also learned a lot from your posts on tpt, so dont sell yourself short in the knowledge dept!
Update on the custom micros for anyone interested
The latest is I went 2 weeks at what amounts to .1 csmb, Mn adjusted to .05, everything else the same. Results were pretty good. I could tell a few things liked the increase, and that it was most likely unrelated to Fe. For example the internodes of Rotala mac variegated have been a little short, but slowly getting better over the past weeks of a steady increase. B and Zn are the most likely suspects for that. A few other things improved as well.
BUT - I also started noticing a few things that seem to happen in my tanks with too much Fe. Red plants turning abnormally dark for example. Rotala indica, which previously stunted a little bit with the aforementioned biomass thing, it's turning abnormally darker green on the bottom, the tips are a deep dirty looking yellow, instead of being nice and bright.
So this past week I decided to go up to .12 (3x week). Things would either get better or worse. Its been one week of that.
What got better - the mac internodes and a few of those type things. What got worse - the too much Fe looking symptoms.
Also developed some gda on the front glass by weeks end. And started seeing a few tufts of bba on the substrate along the very front edge of the right side. I used to get this in the 75 before I started REALLY reducing micros. Havent seen that in probably a couple of years. But here we are.
So it seems like the extra traces were appreciated, but the higher Fe was not.
Starting this week Ive made a new batch of micros, Fe is still .1, but instead of everything else being in relation to Fe, it's in relation to .05 Mn, which amounts to about 75% higher than dosing according to Fe. Thats a pretty substantial increase, but it makes sense if you think about it. Why adjust the Mn and not everything else? Obviously just a theory atm.
I have a feeling it's still going to be a tad too much Fe, but closing the gap between the other micros might help. If not then I'll go back down to .075 or something like that, keeping the higher ratio of non-Fe micros.
All these issues are minor fwiw, things that under close scrutiny only I would probably notice. Between .075 and .1 seems like a pretty sweet spot for just about everything, just not quite there yet. Far better than with csmb though. Soon as I made the switch, and ever since then, in all four tanks it was like everything breathed a huge sigh of relief.
Clear as mud, right?
