I have an ADA AS on my 29 Gallon, im wondering if i do still need to dose EI Dosing?, it seems that my plants are doing fine without dosing, im just afraid that algae may start once i dose ferts

Dose ferts so that your ADA AS won't get "exhausted" too quickly.

That's what I read too, but how much should one EI?

ADA suggests dosing only Potassium until the tank is mature.

I just re-did my 75 with AS and PS, Knowing what was suggested the first week and a half or so I was doing about 3x water changes dosing only K after each WC. Its been set up for a few weeks now and WC's are down to 1-2 a week, plants have slowly started to show new growth, and I have been testing the water to see where I was at. Basically it appeared that there was a fair amount of N being leached into the water colum, but little to no P.

For me I decided to rely pretty heavy on substrate ferts, I am using tropica root tabs, basically shooting to have the bulk of nutrients supplied and maintained via the substrate. But in addition to this to keep water colum levels stable, and in an effort to not exhauste the substrate to quickly, I am doing lean daily doseing of the water colum.... around 1-1.5 ppm N and about .6 ppm P, also a fair amount of K are being dosed daily.

That being said it is working for me so far.... but choose what fits for you best, If you had luck in the past using EI, and adding an excess of ferts several times a week, and you were pleased with the way it worked, then by all means do it with your new set up. Though Im not really sure you would need such excess with such a nutrient substrate

yeah, I read about only dosing potassium too.

i think for now, i need to dose half of the recommend dosing. what do you think, or i should buy those Brighty step from ADA

For my newly setup 40 gallon tank with Aquasoil, I dose the below lighter EI,1-2x a week:

20-40 Gallon Aquariums
+/- ¼ tsp KN03
+/- 1/16 tsp KH2P04
+/- 1/16 tsp Trace Elements

Then a 50% bi-monthly water change. Plants have been responding very well with no stunting, new growth, and good coloration all around.

oh yeah, how about the fish? i though the safe way is to WC every week. Right now i dose K.

John N.

It's a large tank, so fish don't seem to care either way. Every two weeks do a waterchange.
