I have a 55 dirted tank capped with Safe-T-sorb. Heavily planted with CO2 solenoid connected to light's timer. Light 4 hours on 3 off rest period and then 4 hours on. 2 T5-HO on back, and a Current marine LED light strip in front.Been using Seachem products but would like to switch over to dry fertilizers to save on costs. Looking at the EI method. Might order them from aquariumfertilizer.com but not sure what I need and don't need. Already have unopened KH2PO4 and CASO4 from a previous used tank I bought.

Thinking I need these
KN03
KH2P04
GH booster
Trace Elements
K2SO4 <- maybe?

Probably going to start with this dosage.
40-60 Gallon Aquariums
+/- 1/2 tsp KN03 3x a week
+/- 1/8 tsp KH2P04 3x a week
+/- 3/4 tsp GH booster once a week(water change only)
+/- 1/8 (10ml) Trace Elements 3x a week
50% weekly water change

1/8 tsp K2SO4 <- Do I still need this?

More questions to come. Like what can I add together to use in a dosing pump I used for dosing all in a reef tank. Would like to automate the daily dosing and the water changes.

Here's part of the tank. The other side is a mess.

The algae is from some plants I was given by some members of the local fish club. I'm not having any algae issues and will soon have the old leaves trimmed back to remove the staghorn and BBA. Already increasing PO4 to reduce green spot algae.

greenleafaquariums.com sells dry ferts too and their support for help is really good. I have their dry ferts mixed into RO water for auto dosing EI

Keep in mind each fert has a maximum solubility at certain temperatures. And micro ferts are a wild mix and therefore harder to mix with ro. Seachems micro liquids can be easier in that case. But buying dry macros saves a lot of money. Just dont mix up more than a two months of dry ferts even with ro water. It will sour.

Typically avoiding EI dosing and trying to find how much ferts your tanks needs when running high light and co2 ends you up with dosing EI anyways. Its fairly accurate.

KN03- Yes
KH2P04- you already have this
GH booster- yes
Trace Elements- yes
K2SO4 <- maybe?- GH booster has K in it

Have you tested your GH to see if you need the GH booster? I have very soft water, so I use it, but many people do not need it.
Some people additionally supplement iron.
Good luck!
