Question Seachem EI Please help revise my conversions!!

Hi, all. For about 2 month i have been using seachems dosing chart for my 40 gallon. Back when i had the 12 gallon low-med light tank with no co2 All was great. Minimal algae and beautiful slow growing plants. Now with my newer tank things have changed which i suspect are to seachems lean dosing quantities. This is why before i buy my powdered nutrients I will use all all of my remaining seachem line. all of the ferts they make lol.
So Lets say I am still full of the seachem line of ferts from my previous small tank, Would I have to just use the fertilator to do EI with the Seachem line? I have a 40 gallon high light(actually soon to be. Right now only top half is high light due to tall tank.) and co2 injection. I am using the 20-40gal regime.

If I convert the tsp of powders to ml of flourish in the fertlator and round it off for ease of dosing, It says to add 15ml of NO3 for 6.54ppm, 15ml PO4 for 0.45ppm, and 15ml of K for 6.81ppm. Of course I add 5ml of flourish comp and 2.5ml of Iron every other day. Are these target ranges good? I would assume that with 0 uptake those concentrations would be tripled by the 50% WC day. Is this dosing correct or am I bombarding my aquarium with too much? If this is correct it just shows how much of a waste of money seachem ferts are for larger tanks and the EI dosing. I will go straight to powdered ferts right when i deplete the seachem provisions lol. I noticed that the seachem suggested dosing is a little lean for high light high co2, actually alot lean. I began to have BGA, now with the added and more excessive nutrients the bga is disappearing from the extra No3 I would suspect. My tank has a lone dwarf puffer and With the seachem recommended dosing of NO3 my NO3 doesn't even register on the test kit. Their own DOSE calculator also agrees with the fertilator for EI amounts. Are these dosing amounts 3x a week equivalent to the powdered nutrients explained in the EI sticky? This is my main concern. Other than that EI is showing an improvement and my fish does not look stressed or anything.

I have not checked your math in its entirety, but from a brief glance, it appears to be correct.

For sure, the bulk chemicals are a much cheaper alternative than trying the EI dosing regimen while using the Seachem line of fertilizers.

It wont take you long to use it up. I was checking phosphorous yesterday and if I were to try and keep it between 1-2 ppm I would use a bottle every few weeks lol. Time to go dry I guess.

Hi AJ

Are you using Seachem's chart or a calculator based on their chart?

A simple method to increase your lean dosing using the above calculator is to enter more gallons in it. Let's say that you want to increase the dosing on your 40g using that calculator, just enter 60g, 80g, 100g or whatever works for you. As you mentioned, Seachem also has calculators on their site.

That's very true. Check out this older post about a comparison.

These are two dosing regimens. One includes K2SO4 and the other doesn't.

This is what I calculated using the fertilator:
20-40gal regime (I entered all 3 ferts in the fertilator and then let it calculate. This way, all the K is included.)
1/4 tsp KNO3 - NO3 = 5.27 ppm
1/16 tsp KH2PO4 - PO4 = 1.61 ppm
1/16 tsp K2SO4 - K = 5.17 ppm

Seachem's Flourish line
F. Nitrogen - 12.1 mL = 5.27 ppm
F. Phosphorus - 53.9 mL = 1.60 ppm
F. Potassium - 9.7 mL = 5.17 ppm


Not adding any K2SO4
1/4 tsp KNO3 - NO3 = 5.27 ppm
1/16 tsp KH2PO4 - PO4 = 1.61 ppm
0 tsp K2SO4 - K = 3.98 ppm

Seachem's Flourish line
F. Nitrogen - 12.1 mL = 5.27 ppm
F. Phosphorus - 53.9 mL = 1.60 ppm
F. Potassium - 6.1 mL = 3.98 ppm

We have a huge difference in the amount of F. Phosphorus to dose. Our dose of F. Nitrogen is close, but your dose of F. Potassium is three or four times higher. Each Seachem product was probably calculated separately which didn't allow the fertilator to add up all the amount of K in each product.

Seachem's recommended dose for F. Phosphorus is a bit antiquated. It goes back to the days when PO4 was believed to cause algae. Their recommended dose is 2.5 mL twice weekly which is 0.07 ppm PO4 and 0.03 ppm K per dose. This shows this difference.

When you are using up your Seachem products, you may want to bump up the amount of F. Phosphorus some and lower the amount of F. Potassium dosed compared to using your calculation amounts if you want. Our F. Nitrogen's dose is close to each others.

wow that amount of phosphorus to dose is gigantic! I also calculated the same way in the fertilator, all at the same time. This means that if i dose phosphorus at the rate of your calculation, I only have about a week left left of F. Phosphorus LOL. Did you put 40 gal as the tank volume?
I am buying dry ferts from GLA right now. What iron supplement would you reccomend? F. Iron always clouds up my water regardless of what day i put
it in.

Thanks.

GLA sells Iron Chelate which hasn't clouded my water before.

For low/med tech tanks I only dose GH Booster as my fert choice which GLA's has iron it along with Excel and I haven't had any problems.

Click on the hyperlink in Post #5. It shows how weak F. Phosphorus is. You would think that I put in 920 gal instead of 40 gal

Seachem's recommended dose is 0.07 ppm of PO4 and EI's dose is 1.61 ppm. That is a 23 times difference!

I don't think that I would dump that much in either. I think my math is right, but that sure is a big wad.

I've always used F. Iron too, but there is some discussion on several forums including this one about the different iron supplements.

Wow, pretty amazing.
Thanks so much for all your info LeftC my tank is beginning to look like a tank since I began reading your threads on the Seachem line. It is a good product too bad it costs so much!

WOW very interesting info. Thank you Left C and others! I purchased the dry ferts since the seachem will be gone by next week. Not that seachem sucks, They are actually very good products just very expensive. Thanks for the help.
