Fertz parameters

Is there a chart that has preferred fertz parameters in a planted tank?

I hate not knowing what's in my tank. I know there are some test that are very expensive ie Potassium, but I can buy kits for the majority of the others.

Please assist.

Why worry yourself with all of that? Read this link. That's all you need.

I don't know how you are doing your water changes or what water you are using. If you are using tap water, call the water company and ask them the for a reading. Why waste money on test kits that are not accurate?

Here is my city water

Silver <5.0 ug/L
Arsenic <2.0 ug/L
Barium 23.4 ug/L
Beryllium <1.0 ug/L
Cadmium <1.0 ug/L
Chromium <1.0 ug/L
Copper 2.4 ug/L
Manganese 1.6 ug/L
Nickel <2.0 ug/L
Lead <1.0 ug/L
Selenium <10.0 ug/L

Carbonate Hard 6 mg/L
NonCarbonate Hard <1 mg/L

Aluminum 0.24 mg/L
Calcium 1.74 mg/L
Iron <0.10 mg/L
Potassium <3.00 mg/L
Magnesium 0.38 mg/L
Sodium 39.8 mg/L
Zinc 0.05 mg/L
Mercury <0.30 ug/L
Nitrate + Nitrite <0.10 mg/L


My main issue and please correct me if I am wrong, but I have Miracle Grow Organic and I thought I wouldn't have to dose my tank (at least for a while)
Right now I am dosing:
2 capfuls of Flourish
3 capfuls of Seachem Potassium
2 capfuls of Seachem Nitrogen (all weekly after 35% water change)

My kh and Gh sit around 9

I was told my calcium and magnesium are low and it wouldnt hurt to add these after a water change.


I just want to make sure my plants are getting what they are suppose to.

BTW here is a pic of the current setup: Left side of the tank

This is actually quite good tap water.

GH booster for more Ca/Mg
Maybe 1-2 teaspoon per 50 gal after water change.

There is no optimal ppm for things, only a "range".

This is what I wrote about 15 years ago but have since raised some values:

Nitrate (NO3) 10ppm-30ppm Add KNO3 (Potassium nitrate) a.k.a. stump remover. Fish load and feedings.

GH 2-8 degrees Add Sea Chem's Equilibrium to raise. Or CaCO3 for both KH and GH.

Iron (Fe) 0.2ppm to 0.7ppm+ Add fertilizer such as TMG or Sera or Kent etc.

Phosphate (PO4) 2ppm to 5ppm Add K2PO4 or fish food or sometimes in the tap water already.

Potassium(K+) 20-30ppm Add K2SO4 and/or KNO3 to boost if you also need NO3. Also in Equilibrium/TMG/Kent etc.

If any thing is over these recommend levels do a water change to lower it.

Recommended Levels:
Temperature: 68 to 84 F and a target of 76 to 78 degrees F or 25 C
Water flow: 5-15 times tank volume per hour (good ripple but not break the water's surface)

Fish load: Light to moderate/algae eaters should be added. Snails are good for this(pond, MTS, Ramshorn)

Lighting: 2w/gal FL,MH or PC's, 1.5w/gal T5 max, LED 3w crees: 1 w/gal max.


Suggested test kits:

pH


Pinpoint pH monitor(much better)
Red Sea low range(cheaper)

KH

Most all test kits are decent such as Tetra/Sera etc.
Lamott are the best

NO3


LaMott(much better)
SeaChem(cheaper)
Hanna meters

GH


Same as KH

Fe


Hach(much better)
Sera or SeaChem(cheaper)

PO4

Hach(much better)
SeaChem(cheaper)
Hanna meters

K+

Lamott
Hanna meters

If these parameters are in a good range you should have only minor issues, if that. You only need light, CO2 nutrients and a balance of these factors and of course a little patience and an eye/desire for the planted tank!

Use known standards for references, otherwise, do not even bother test, as the result will be unreliable.


You are just guessing if you do not use reference standards FYI. So tedsting is a waste of time therefore if this step is not done.

Tom Barr

Use your plants and sometimes algae as indicators to what nutrients are missing.

Thanks Tom I knew I could count on you.

I have everthing else in place
1. Pressurized Co2
2. Lights for sure
SO I think Fertz is my next step - which is why I went to the Miracle Grow to avoid Dosing - But I am not even sure IF I need to dose, that's why i am wanting these test kits/


ALSO what do you mean by "Reference Standards"?

I just picked up Seachem Trace, so now I have

Nitrogen
Flourish
Trace
Potasssium
Excel

I honestly think next month I might seriously look into the dry Fertz.
