Wet's EI modeling calculator with graphical output and dosing calculator

it works fine in Google but looks totally different and doesnt work in IE 9.

 

Oh god. I'm sorry man, I just never think about IE and now understand forcing folks to the new calc without testing IE was pretty lame.

http://calc.petalphile.com is back. You might need to clear browser things. http://rota.la is still up. Same for ei.petalphile.com and rota.la/ei, respectively. I'm not sure I can make time to get them right before AGA. I'd still love more bug reports.

Thanks!

 

Thanks Wet. Your work is a Godsend for us Chemistry challenged hobbyists.

 

rota.la and rota.la/ei should be friendly with IE now. Please let me know if it is not via github.com/flores/yet-another-nutrient-calculator or here/various forums here/APC.

Thanks!

 

I have one small note. On rota.la you replaced text "using" which as between aquarium volume and fertilizer kind to "fertilizers" and whole "sentence" sounds quite strange now... at least translated Maybe it would be possible to change it to "and I'm using fertilizers".

 

Nice, thank you. Added that translation back. Will we be able to use your existing translation or do you think it needs to change?

Thanks Tomek!

 

Yes, at least for Polish is OK.

BTW I noticed, that you automatically add chart panel so probably text "Want to model long term effects [...]" should be changed after code stabilization. And I noticed error, when I calculated for result of my dose, chart part was opened, but without numbers. For other calculation method, chart part was not opened error "Stuff must be a real number. Your water change amount must be a real number." was thrown.

 

Hi everybody,


http://ei.petalphile.com/ has been down for a while, does anybody knows similar calculator? or formulas to make your own?

 

Greetings,

I've just starting to use fertilizers but I have a few questions. I want to use the EI to get a handle on things, so I went over to https://rotalabutterfly.com/nutrient-calculator.php and filled in the values for my tank:

200 Litres, using Aqua Rebell Makro Basic.

It comes up with 163 (!!!) Milliliter of the stuff to reach 7.5ppm NO3.
It also says I should dose this 2-4x a week. This would basically mean I need a bathtub of some sorts to keep enough fertilizers in, lest I be running up and down to the LFS every other day.

Now, I've looked on the bottle, and it says, that it raises NO3 ppm by 1 for every 2 milliliters of the good stuff per 50L, so in my case (200L) that would roughly be 8ml for 1ppm up. It follows that if I believe the instructions on the bottle I need 7,5 x 8ml for that 7.5ppm total. That is 60ml.

Now there is quite a discrepancy between the 163ml the calculator gives me, and the 60ml according to the bottle. Additionally, it seems to me that dosing even that 60ml a couple of times per week also means I need a couple of buckets somewhere.... I've been trying to find a decent calculator since forever, but all links are either dead or don't specify what ppm I need to add specifically but instead tell me to add "x amount of spoons" to my aquarium. Which to me sounds rather unscientific.

For the record, I have a ph controlled CO2 bottle and 2x 24inch Current Satellite Plus Pro lights. My amount of plants is pretty decent, but nothing at all like a full Dutch-scape. I'd say about half of what a fully planted tank has.

What is the best course of action to follow in my case?

(Or could you point me in the direction for a good indication to how long I should set my light cycle, how much I need to drop ph using CO2, and how much ferts I should add?)

I greatly appreciate any and all help I can get, thanks in advance!

 

Are dry compounds available in you area? Mix your own, easier on the wallet too.
The Aqua Rebell seams more expensive than Seachem's water.

Which aqua rebell product do you have the calculator does not list them all?
Several Makro Basics are listed on their website.

My tanks have a 6.5 hour photoperiod, and approximately 30ppm CO2 levels give or take a bit.

 

As far as I know there is only 1 aqua rebell makro...

As far as powder goes, I havent a clue what is available. All I figured was that ppm was the thing I have to look for.... But for such a famous thing, Estimative Index doesnt seem to have any conrete calculators anywhere. So how is one to follow the EI? I'm super puzzled.

As for CO2, how do I know how much ppm I have? Are there test kits? Additionally, how many lumens does your lighting produce? How much do mine produce?


So many questions... and nobody seems to have any answers... Thanks a lot for your input though!

This represents a standard EI group of compounds.
Dosing and mixing instructions on this site too.

Measuring CO2 is about a 1.0 drop in pH.
Measure tank during peak CO2.
Degass a sample with airstone for half hour and measure.
Degassed - peak CO2 = about 1.0 for 30ppm.

I run 100PAR @ substrate.
No idea how many lumens this is.

Basic stuff here, all over the web

 

Thanks for the link.

How much is a "gm", is that an abbreviation for Grams? Because on the page where they list the amount to mix in a 500ml bottle, they speak of mg's and gm's. Is that a typo by the author? I ask this because lower on that same page where they list the PPS-PRO dosing method they use g's as would be expected as an abbreviation for grams.

As for my CO2 ppm question, I can just set my pH controller to lower the pH by 1 point then?

But please don't be too condescending, it is not all over the web. I have looked everywhere, Hence I came here, to the source. In fact, all the links before my posting in this thread don't even work. There isn't a calculator on the site. And I just thought that was a bit odd for such a famous index. Personally, I thought offering a calculator on the site of the person that came up with EI to be considered "basic stuff", but who am I... Anyway I will refrain from asking any further questions.

 

All the info is here!

Good starting place in this link.
It has many links to other references also.

Dry dosing is easy but many have solution recipes for certain size tanks with recommended doses.

Zorfox calculator is another you can download to your PC.
