Expanded Dosing Chart - Did I get it right?

Hey Guys,

Can you help me verify that I am scaling this properly? I took the formula here: https://www.plantedtank.net/forums/fe...-regimes_.html

I put it in Excel, and with a little formatting, i just let Excel start creating 'series'.

Based on the calculations alone, I would say yes. Let's see if we can get anyone else to weigh in. Great table.

I would love that table then broken down for dosing after mixing some amount to 500ml of water... I like to dose liquid with a medicine syringe... much easier to be accurate with 5ml amount that 1 tsp of powder

Note that for a 40 gallon tank you can follow the 20-40 column or the 40-60 gallon column. So, the accuracy needed for KNO3 for example is 1/4 to 1/2 tsp. That is 3/8 +/- 33% accuracy. Don't worry about the accuracy. The big advantage of pre-mixing is for small tanks, where you are dealing with 1/16 tsp quantities, which requires a set of the tiny measuring spoons, but if you make a bottle of premix with 16 doses in it, you can use an ordinary kitchen 1 tsp measuring spoon. Then you dose 1/16 of whatever the bottle holds per dose.

* You may want to reduce the fractions for CSM+B to the lowest CD. ... 4/16, 6/16, 8/16, and 10/16

* Also, you don't have a listing for aquariums smaller than 20g.
From: http://www.barrreport.com/estimative...chy-folks.html
10- 20 Gallon Aquariums
+/- 1/8 tsp KNO3 (N) 3x a week
+/- 1/32 tsp KH2PO4 (P) 3x a week
+/- 1/4 tsp GH booster once a week(water change only)
+/- 1/32 tsp (2ml) Trace Elements 3x a week

* For aquariums 40g to 60g, CSM+B should be 1/8" tsp and not 1/16 tsp.
40-60 Gallon Aquariums
+/- 1/2 tsp KN03 3x a week
+/- 1/8 tsp KH2P04 3x a week
+/- 3/4 tsp GH booster once a week(water change only)
+/- 1/8 (10ml) Trace Elements 3x a week

You should look at this again, WarDaddy.

A 40 gallon tank with low plant mass/CO2 in the first column would get !/4 tsp KNO3. The dose for 60 in the second column would be for a tank with low plant mass/limiting CO2, etc. You could even add a 10 - 20 row, that way.

For the Fe/iron row, (do you mean DTPA Fe)? It might be better as a 1:3 ratio; 20 gal tanks get 0.1mL DTPA Fe

Commonly, recommended dose for Gh booster should start at 1/4 tsp for 20 gallons, for most water.

If your chart works, the last column could give ppm. Each row should = the same ppm concentration +/- 33% accuracy. Or include target ranges (10ppm NO3, etc.) in the last column. It’s much easier to talk about concentration rather than number of milligrams in a tank because that way we can compare two tanks directly without regard to their size.

Thanks for the feedback guys.

I have a strange brain that just shakes in fear and breaks down when math pops up. (I have a learning disability called Disgraphia that is probably a fair measure of the issue).

The reason i worked on this chart, is that i am trying to successfully bring up a 210 gallon planted aquarium. I have had one aborted start on it due to the suspect introduction of a bushy nose pleco that decided he liked my plants more than his wood and let me tell you... hard fish to catch in a massive planted tank. (impossible actually, w/ 3 people trying too!)

Thankfully thats over, the tank is rebooted, and recovering from it's destruction.

I decided not to dose the KH, my PH is allready 8.8 from the tap because we get our water from a limestone aquifer. so I am not convinced I need a KH booster.

I'll see if i can find where i put the excel chart and make the suggested corrections and repost - i upgraded to windows 7 last night and im still sorting out where i backed everything up in my excited rush. (love it btw.)

That's GH booster, and it will not affect carbonate hardness or the pH. Primarily it's potassium (K+) with some non-bicarbonate forms of Ca and Mg. Adjusting the doses for GH booster can very from adding none to adding just enough to raise the GH by 17.9 ppm. CO2 will bring your pH down and without CO2 the chart is not much help. EI was developed for plants growing under high light with lots of CO2. So people like you and rich815 don't need to do the math.

Plus there are fewer water tests.

One of the best words of advise yet. Your fish bioload, how many times you change your water and your plant mass matter WAY more than being off by 1/2x or 2x as much fertilizer. Just dump in the amount of powder that's close. Makes the math part really easy.

lol well thanks!

I actually do run a CO2 system. I forgot the model of the reactor, but here is the regulator:

The tank is lightly stocked right now. recovering from my neglect over the last 6 months. Got a puppy and one of my co-workers quit, so ive been run ragged.

It looks like you worked on the errors, but you forgot one. Here you go. It was also mentioned on the bottom of post #5.
