Help with adjusted EI recipe

[nijat11]

Hi all!
Soon I will get my 1300 liter aquarium (~325 gallons). In my previous tank I was using EI method and it was working like a charm. But taking into the account the size of tank I would like to switch from weekly to be-weekly water changes (because of money and dont want to waste 650 liters of water every week). Another reason, why I dont want EI method, I have other tank where I dose masterline gold, and I can definetly see better coloration and less algae issue (especially GSA).
I need an advise for a recipe for my new aquarium heavily planted tank. As substrate i will have base layer + aquasoils, capped with fine gravel. CO2 injection and aquatlantis easy led 2 lights. Turnoever 8000l/h + masxpect gyre xf330.
I`m kindly asking every member of this forum who gonna to reply this thread, please do not start fight on EI vs LEAN.
Thank you in advance!

Do you use the IFC Fert calculator? if so, it has different EI recipes - from full, down to Mid and Low EI.

Hi all,

masterline gold

<"MasterLine - All In One Golden - 500 ml"> It is pretty near the mix ratio from <"Solufeed 2:1:4 and Solufeed Sodium Free TEC or Solufeed Coir TEC Combination">, just with less nitrogen (N) and phosphorus (P).

MasterLine All in One Boost Ingredients

Nitrate (N): 0,68 %
Phosphate (P): 0,15 %
Potassium (K): 3 %
Magnesium (MG): 0,3 %
Iron (Fe): 0,21 %
Manganese (Mn): 0,055 %
Zinc (Zn): 0,047 %
Boron (B): 0,032 %
Copper (Cu): 0,007 %
Molybdenum (Mo): 0,005 %

<"Call me cynical">, but it will be a <"commercial trace element mix"> and may just be a horticultural fertiliser diluted and re-branded.

cheers Darrel

Thanks for the tip! It was actually my idea to dose half of EI and see the results. Also need to experement with 30-40% water change every 2 weeks, to see the results.

I'd try that, or the <"Duckweed Index">. If you are set on CO2, you could always use a lower CO2 level (~15 ppm). I think @Marcel G is an advocate of this.

Soon I will get my 1300 liter aquarium

I would really want <"slow growing"> rosette plants, otherwise the <"maintenance requirement"> is going to be immense. Personally I would look on slow growth as a friend, and I wouldn't want to add CO2, or EI levels of fertiliser.

I completely agree with you Darel. But my lack of skill and lack of patience leads to algae outbreak, especially Staghorn, so running it without CO2 really hard 😀. I dont mind to spend 3-4 hours per week on maintenance, so probably I will add some steam plants, but not the entire aquarium 😀.

Good on you. I'm <"just incredibly lazy"> and always take the path of least resistance.
