# seachem conversion oh my!

I want to substitute dry ferts recommended for the non co2 by Tom Barr, with seachem flourish macros and trace

Problem is, I'm not sure how to calculate the amount needed... Using this data:

1/4 Teaspoon of Seachem Equilibrium (for traces and Calcium + Magnesium).

1.42 ppm Ca
0.42 ppm Mg
3.43 ppm K
0.02 ppm Fe

1/8 Teaspoon of KNO3

5.27 ppm NO3
3.32 ppm K

1/32 Teaspoon of KH2PO4

1.61 ppm PO4
0.66 ppm K

Do I just add up all the numbers from the dry ferts and punch them into a fertilizer calculator ?
Fore instance adding up the potassium I would get 7.41ppm of K... so would I then use let's say 11ml seachem potAsium for a 20gal?

Is this how it works?

I can't find this info on this forum yet...

Thanks

I'm not up to doing math atm =P, but. You can use Epsom salt (potassium sulphate) and plaster of Paris (calcium sulphate) to fill the =librium's place and they are super cheap.
I am interested in exactly the same thing.Very curious about this one,too.Maybe some of the more experienced members could help.
Yes, that's how it works.
Okay great!... but of course I punch in the seachem nitrogen into the calculator and apparently it has other macros in it as well like potassium... so if I just start with nitrogen fert at the recommended dose and make sure i adjust the levels of P and K, everything should work out to right dosing...

Thanks!

Anyone know if there's any reason to use flourish trace over comprehensive? I won't be using equilibrium as my water is liquid rock at gH of 24+ and kH of 16+

It has Nitrogen (derived from KNO3 and urea) and potassium. If calculating for Nitrate (NO3) using the Seachem calculator make sure you divide the result by 4.4. It reports total nitrogen not NO3. I realize the calculator says divide by 5 but 4.4 is more accurate.

You can use this calculator and the conversions are done for you. However, it does not account for the extra nitrogen from urea.

Flourish comprehensive provides small amounts of macro and secondary nutrients including iron. Flourish trace does not. However, Flourish trace has Rubidium (Rh), Nickel (Ni), Vanadium (V) which comprehensive does not have. I doubt they make much of a difference but that's a guess.

I assumed you wanted to use Seachem products because you have them already. If you intend on purchasing them I would get dry fertilizers instead.
Sorry to barge in ,but ,is that calculator more precise with Seachem products than with Easy Life ones? I mean ,are the Easy life products more/less concentrated than on their labels?
I have read about some issues about one of the labels on Easy Life ferts ,and wanted to make sure.
Is Seachem a "cannot go wrong with it" brand?
Can't help on the Easy Life thing but see if this calculator works for you.

Ordinarily I'd say fish can't live in your liquid rock.But unless you live more than say 50 miles from where you got them, the store where you got them likely has them in the same water.

But for SWTF: It may help you to know that most of the nutrients are not bad if only slightly overdone. The Trace eliments can
be and the Phosphate can be however but still needs to be over what you would call "slightly".

Thanks Ray ,
I am actually looking for a reliable fert brand ,one which is found in most online nutrient calculators ,and on which I have plenty of info available.
I couldn't find powder ferts in the shops around here, only the Seachem and Easy Life brands.
Is there any major difference between the results given by "fishfriend" and those givne by "yet another calculator"?Should I use both and then make an average out of the two for my dosing?
And what does SWTF stand for?I've searched online ,but gave me some nudity related abbreviations
