When other people dose EI using RotalaButterfly do people select,
“I AM CALCULATING FOR: Estimative Index”
“I AM CALCULATING FOR: Dose to reach a Target”
When I first started using RotalaButterfly’s Calculator to estimate my fertilizers that I would be dosing I put in all of my information (20g, DIY, Element, Dry Dosing...) and at the bottom when I select “I AM CALCULATING FOR:” I had been choosing Estimative Index…
Which gives me these target levels:
-NO3: 7.5 ppm
-PO4: 1.3 ppm
-K: 7.5 ppm
-Mg: 5 ppm
-Iron: 0.2 ppm
I decided to go though and select “DOSE TO REACH A TARGET” and put in these levels…
-NO3: 15 ppm
-PO4: 2.0 ppm
-K: 15 ppm
-Mg: 10 ppm
-Iron: 0.2 ppm
Do these new target ranges look safe for me to dose, I found these ranges on BarrReport at:
My tank is a 20g Long with a Finnex Planted+ 24/7 SE that runs on 24/7 mode so seeing how my tank is only about 12” tall I can safely say that it’s High Lighting…
I was told I could dose CaNO3 in place of KNO3 so I wouldn’t have to dose Equilibrium (I used to dose but I run through it to fast having several tanks).
I agree it does look like chlorosis which would be an iron deficiency. The only iron you're dosing is from CSM+B right? What is your ph? As I mentioned in your other post this could be the same thing Burr740 was seeing in his tanks. The iron in CSM+B is EDTA. His thinking was that because of the higher ph in his tanks the EDTA essentially becomes useless. So despite dosing higher levels of CSM+B the plants weren't getting enough iron. Which is one of the reasons he switched to mixing his own micros, using a combination of dtpa iron and gluconate among other tweaks. When I had a similar issue I stopped using CSM+B, and switched to Flourish which uses gluconate, and supplemented with DTPA, and my problems started clearing up in a week or two. Like I said I'm not an expert in this stuff, but that's what worked for me.

My pH is a steady 6.5 in all my tanks I use very soft tap water and when I dose my ferts I also dose alkaline/acid Buffer at a 1:1.3 ratio to raise my KH from 2 to 4.8 and ph at 6.5... Yesterday I dosed Flourish Iron (0.1ppm) with my Plantex CSM+B (0.2ppm) which I did because I thought maybe the Fe in the Plantex wasn’t doing its job which should have came out to me dosing Fe 0.3 ppm…
I do not dose my Macros and Micros at the same time FYI.
I don’t know what EDTA and DTPA are or how they are applied, I did look them up on google so I kinda have an idea of what they are but still do not understand...
When you say you switched to Flourish do you mean regular Flourish or Flourish Iron?
Oh man I hope this isn’t my problem...
I found this thread: ( https://www.plantedtank.net/forums/#/topics/503585
Toxicity of CSM+B
First of all let me start by saying that csm+b can become very toxic to plants when overdosed, the effect is so bad that it would burn your plants while making you believe that you are suffering from other deficiencies, however it is also true that some plants will respond to the toxicity more than the others and some might not respond to it at all, Plants like HC will show such an effect where leaves would start to suddenly disappear.
I would like to share a story about HC plant, every time I tried this plant it would suddenly start to disappear, I tried it so many time till now and I simply couldn’t grow it, on the other hand I can grow Erio which supposed to be harder to grow, the culprit was too much CSM+B, I had all the other nutrients, co2, lights at unlimited levels.
Many people here overdose the csm+b very easily while trying to keep the Fe level high, even too much Fe isn’t good either but we will talk about that later. Some people who think dosing more csm+b brings out more reds in their plants are only making things worse, if you are overdosing with Csm+b to get the Fe levels up then you will get a toxic levels which look exactly like Fe deficiency, that is because Fe toxicity seems to damage the sulfur uptake mechanism and sulfur deficiency looks similar to iron deficiency, it also depend on what kind of iron chelate you are using, iron gluconate doesn’t last in the water for long time and toxicity from this cheleate is less likely to occur even in high doses around 1 ppm, toxicity from other chelate iron such as EDTA, DTPA poses higher risk. Next time you dose CSM+b watch out for overdosing it.
Could this be my problem, that I am overdosing my tank when it comes to Plantex CSM+B???
I have been Dosing 232mg of CSM+B the calculator told me that was the correct amount to dose 2-4 times per week in order to keep Fe at 0.2ppm… I thought it seemed like a little much but then again what do I know about these things.
Do you this this is what is happening in my tank from what you can see in the photos?
If so… Elusive77 could you or anyone else help me possibly find an alternative routine to dose my Macros sufficiently and succesfully?
I have thought about Dosing Iron when fertilizing because it states that it is ferrous iron gluconate supplement which I think means I do not have to worry about it bonding with my other ferts and it is Fe+2 instead of CSM+B which I think might have Fe+3 making it harder for my plants to absorb...? (Can somebody fact check this please?)
How would I dose my other Micros, will Regular Flourish
do that and can I dose Flourish Iron
