Exclamation EI Dosing liquid ammounts

Hello,
So I am trying to figure out the proper amounts to dose for the EI method using a liquid solution instead of the dry dosing method. Please forgive me if this has been answered a thousand times, but I wasn't finding any good information and wanted to confirm with everyone.

I have a 25 gallon aquarium which would fall into the traditional 20-40 gallon dosing bracket ifI were to dry dose my ferts. I was wondering if i should make my liquid solutions using the 20 or 40 gallon ammounts given to me by the sticky calcuator?

The reason I ask is when I first started dosing EI, I made my liquid solution using the 20 gallon amounts, which worked great for awhile....until my aquarium got much more dense with plant life. I believe I am having some nutrient deficiencies, especially with my ludwigia (great indicator plant in my aquarium) and was considering making new fertilizer solutions for the increase 40 gallon amounts!

Any input will be greatly appreciated!

The fact that ei suggests you dose a 20 gallon tank and a 40 gallon tank with the same amount should tell you that ei is not an exact science. If you feel you need more add more. Having more than enough is what you want. The plan calls for a 50% water change at the end of 7 days so if you think it is too much just reduce it the next week.

So I should not have issues dosing a 40 gallon amount of fertilizers in a 25 gallon aquarium as long as I follow the EI dosing schedule and do my weekly 50% water change?

What are you using? Just double the 20g amount and go with that. I live in Centennial. I don’t use gh booster. I use tap water which is high in calcium. I find extra K is a good idea so I dose Potassium Sulfate. I add a little Epsom salt once a week or so. I tend to think Iron is a good idea.
Lack of nutrients is more of a problem than too much. There is no exact science here!

These recipes don’t even agree.
20~40gal
50% H20 change-weekly
1/4 Tsp-KN03 3x a week
1/16 Tsp-KH2P04 3x aweek
1/2 Tsp-GH booster once a week
5ml or 1/16Tsp-Trace 3x a week
Optional
1-2ml-Fe/Iron 3x a week

20-40 Gallon Aquariums
+/- tsp KN03 3x a week
+/- 1/16 tsp KH2P04 3x a week
+/- 1/16 tsp (5ml) Trace Elements 3x a week
50% weekly water change

Is it possible to overdose with this amount and further more, are there signs that will tell me if I need to cut back on this dosage? Will there be algae or some other symptom to signal this?

No, if you follow the recommended dosage amounts, you will be fine and not overdose.

More often than not, algae is the result of a lack of nutrients, not an abundance.

More issues with not enough current and not enough CO2, ferts should be plenty for even very high light weedy stem plant tanks.

So more trimming, water changes, cleaning and CO2 will help.
