I have a 150 gal tank. the ei dosing chart only goes up to 80 gals. is there a chart for bigger tanks? I just ordered from gls npk, plantex csm +b and iron chelate. What would be the best way to liquid dose and how much?
I have one too, I use 20 ounce soda bottles and 50 ml syringes, I make my mix according to a 50 gallon tank and the multiply by 3 or if you have a super high fish load with good nitrate you can back down accordingly.
It's hard to say how much but you will need the CO2 before you'll need much in the way of ferts, a photo with plant mass would help but just try to hit the proper targets and for now they are low, nitrates 5 -10 ppm.
EI dosing for a 50 gallon tank:
2-3x a week:
1/2 teaspoon KNO3 - mix 5 tsp per 200 ml of water = 20 ml dose per 50 gallons of aquarium water
1/8th teaspoon of the KH2PO4 - mix 1 & 1/4 tsp in the above solution actually here I have bumped up the phosphates to 1/3 the total of the KNO3 or 1 & .66 teaspoons
Add K2SO4 after water change, say 1 teaspoon
CMS+B, I'd add 1 TABLE spoon into 500mls of water, 1 teaspoon of MgSO4(Epsom salt), dose 15mls 3x a week
Fe mix DPTA 11% Iron Chelate, I use one Tablespoon of Fe with 500 ml of water.
The only thing I'm doing different is using Barr's gH Booster instead of the recommended K2S04.
Remember it's the Estimative Index so close is good and no scales required, it is designed to be flexible so adjust the dosing to fit your needs.
Start with any of the EI recipies, and multiply it out. All the recipies are the same when you figure out the dose per gallon, and there is a factor of 2 in there. See the recipe for a 20 to 40 gallon set up, for example?
If you are running a high tech 20, this is good, or if you are running a low tech 40 this is good.
There is such a wide range of possibilities, just get started with something, then adjust as needed.
However, in that tank I would really just put some tablets under the plants, and not dose the water column.
Plants in the sump (is that what it is? Second pic). The plant in the front left is a house plant, not an under water plant. Dracaena. I see 2 of them.
Yeah, I don't know why some LFS sell plants that aren't aquatic just because they will survive for 30 days under water. Our LFS does the same thing along with the dyed fish, to me it's just foolish to trick people or torture something because a five year old thinks it's pretty.
