Question How much iron to add?

Newb here...

I been using the Seachem Iron but I wasn't sure how much to use, because it says to add enough to keep the water at .10 mg/L of iron. But I do not have a test kit for that, and it doesn't say how frequent to dose.

I can buy the kit, but it's $17 on amazon. ugh. I'm asking how much should I plan to add with a 75g low tech tank with Satellite+ LED, and do I need to buy that kit? Are their cheaper alternatives?

Hi,

I do not think a test kit is necessary; more information is if you want meaningful advice… Otherwise I am sure someone will be along to randomly advise you.

If your Guru tells you otherwise and you are true believer that is okay I will not argue the point.

I pretty much limit what I say to things that anyone can easily verify from recognized references or by direct observation. If it is my opinion I say so.

I would think that you will need a Pipette to use/w that liquid.
I can't verify that amount in PPM as being a correct amount to use.
But the calculator on that link can give you the number of ml you need
to get any number of ml you want.
And of course for yet another complication, every time on here that PPM of iron is recommended, as I recall, it gives it in Gallons.
Since iron is used in a wide "window" by various people I would think that a 4/1 conversion on liters/Gallons would be close enough. But once you get past, say 40g tank the discrepancy gap begins to widen on that conversion.
So...http://www.thecalculatorsite.com/con...llons-(us).php

The shortest distance between any two points is a straight line...in the opposite direction...

mg/l is the same as ppm

+1 on the no test kit..

The advice of "keep at xyz ppm" is absurd. To do this you would have to measure your level regularly and re-calculate your dosages as plant absorbtion goes up and down. Trying to do this is a gigantic headache and very much out-of-style these days.

Pick a non-limiting dosing regime and use its dosing as a starting point. Adjust from there based on plant behavior.

Given your low tech setup, Perpetual Preservation system (PPS), or EI low-light are probably good starting points, depending on how you plan on doing water changes. EI needs weekly 50% water changes to limit nutrient levels, PPS does not but generally results in slower growth (it is a low maintenance profile).

These schemes exist to take the insanity of testing out of fertilizing aquariums. Read up on them, really..

When you're ready, there's a few good calculators out there to help you calculate exact dosage and frequency.

PPS-Pro is where it's at! It has always worked for me Well, at least in the one tank I used it in...

I should have specified PPS-pro, not PPS, as someone might think that I meant PPS-Classic, which is really a version of the 'do a lot of testing to maintain levels' approach.

That said, all the calculators don't specify "pro", because there's no prescribed dosages for PPS-Classic.
