Nutrients directions for my 10 gal bubbler

I have a water soluble nutrient its 15-15-18 its blue powder came wit a little meassuring cup anyways.... Its a premium quality house plant fertilizer that dissolves instantly dual feeding action uptake through roots and foliage for better results....


Well i have a 8 gallon tank and i dont no how much to put in so maybe you can help me heres the directions

mix 4 ml of fertilizer per liter of water


so how many ml do i put in a 8 gallon tank?



Thanks everyone im a rookie here on this crap

and is 15-15-18 good?

8 gallons equal about 30 liters. So it looks like you need 120ml. I don't know anything about your nutes though

ya bro sounds a bit strong also when you are growing hydro you want a three part nutrient that way you can change the dosage that the plant will need at every stage of the grow I use the general hydroponics 3 part solution and the floramicro is 5-0-1, florabloom 0-5-4, and floragro 2-1-6 here is the table i use. http://genhydro.com/genhydro_US/feeding_charts/GH_KeepItSimple_Recirculating.pdf


hopefully this helps.

is it 8 or 10 gallons? and if its a bubbler then your not filling it to the top right? prob 1/2 or less. i aim to keep the water line .5 to 1 inch below the containers.

use a measuing container and figure how many litters you need to get the water at the correct level(might need to write it down, i lose count and forget how many litters i put in) and add the according amount of nutes and make sure the ph of the water is in the 5.5 to 6.5 range.
