Water Report

How can I use this water report to help understand water parameters and my dosing needs?

My tank water hardness is high and new growth appears to be lacking Iron. My maintenance is lax where I do not vac the bottom and only manage 20% water change a week.

Trying to understand... Do I still need Nitrogen and GH booster?

Iron in the water is not always available to the plants. The level in your water is pretty low. If the plants seem to be showing iron deficiency, then dose with chelated iron.

TDS is mid range. Perhaps some shrimp might not like this, but it should not be a problem for any plants.

Ca is reasonable.

Mg is quite low. I would dose Epsom salt. A GH booster will have calcium, and the calcium in this water is OK, do not need to add more. Just magnesium.

pH is high. Often the water company will add something to keep the pH up, but in this case it looks like the KH is already pretty high.

Alkalinity (KH) is over 10 German degrees of hardness. This is fine for most live bearers, rift lake fish, many Rainbows, but it will make altering the pH very difficult. I would not try. Plants ought to be OK in this, but some nutrients may not be as easily available at the high pH. If this actually is a problem, then lowering the KH will be the first step in controlling the pH.

--------------------------------

Have you tested your tank for
ammonia
nitrite
nitrate
pH
GH
KH
Do you have any other tests?
What are the results?
Can you tell us how you are running the tank now? How many fish? What kinds of fish?
What kind of light? How long is it on?

THANKS

api tests

ammonia 0
nitrite 0
nitrate 40+
pH reads dark blue on regular test and reddish on high ph test
GH 18
KH 11

Light is a Planted+ 24/7 on about 8 hours custom profile. Suspected full sun was too much cause of algae outbreaks. 21 inches to substrate.
Previous light was Stingray with added strip LEDs.
Ferts are Flourish comp no schedule these days other than a mil here and there through week.
Macros same as above, whatever I mixed from some dry ferts someone gave me.
Excel same as above.

Tank has not been growing much in several months.
I dont expect much but I am trying to come up with a routine. Been set up for over a year.
Want to order some proper ferts from member here nilocg.

API pic is ammonia nitrite and nitrate.
Tank pic is sad but its been worse.

Bump:

Bump: This plant is in a bad position I know, but this leaf grew out yellow.
An anubia leaf also grew out yellow and seemed to melt away.

This plant is in a bad position I know, but its leaf grew out yellow.
An anubia plant leaf also grew out yellow and melted away.
Never had leaves grow out yellow so must be bad news.

Always include the units when you report test results. Are the GH and KH in degrees?
pH in those colors seems to suggest about 8? Is that what it looks like to you?

Sporadic dosing may be part of the problem. Lets figure out some kind of schedule and stick to it for about 2 weeks, see what happens.

Very lightly planted, and most of the plants are not noted for being really fast growing or 'nitrate sponges'.
NO3 is high, perhaps from fish food?

Fish food is high in N, P and most traces. If the NO3 is high from fish food, then these other things are high, also.
Fish food is low in K, Fe, Ca, Mg
Water seems to have plenty of Ca, but not much Mg.

I would calibrate the NO3 test before relying on it too much, but if it is right, here is what I would do:

50% water change to reduce the NO3 and other things from fish food.

Dose potassium, chelated iron, carbon (excel or similar) and magnesium. You could dose very small amounts daily, or a bit more every other day. I would not spread out the dosing more than that, though. Make the conditions as close to stable as possible.
Do not dose N, P or traces (except for iron)

Try this regularly for 2 weeks and monitor test results and plant growth.
If the NO3 keeps going up repeat water changes as needed to keep it between 10-20ppm. This ought to keep the other nutrients from fish food in the right range, too.

Thanks for the help. I have some ferts on the way and I will do as you suggest.

Using the "yet another nutrient calculator"... 37 gallon
Should I calculate for "what dose to reach a target" or one of the other choices. "Low light" is only weekly.

I prefer the fertilztor at Aquatic Plant Central.

Dose 1/2 tsp K2SO4 to raise the potassium by 10ppm. I would split this in half and dose 1/4 tsp 2 days per week. If you start seeing things turn around, then you could try adding another 1/4 tsp one more day per week (every other day). You could mix this with chelated iron and dose them at the same time. start with 1/2 tsp K2SO4 in 3 ounces of water and dose 1 ounce per day, every other day.

Chelated iron (DPTA-Fe) dose 1/8 tsp weekly, I would split this and dose it 3 days per week. Even chelated iron gets locked up pretty fast. (easy: put 1/8 tsp in 3 oz of water and shake well. Add 1 ounce to the tank every other day)


Epsom salt: Lets see what 1 teaspoon does to the GH. It should come up just a little bit. Dose once, let it dissolve, and test. If you can see a tiny change in the GH, good. You might add 1/2 teaspoon every other day or a bit more until the GH rises 1 degree. By the end of a week (3 doses) the GH may not even come up by 1 German degree of hardness, but measured in ppm, this much will about triple what is there now (which is a very low amount- I am trying to reach a ratio of Ca: Mg of something in the area of 4:1). This also can be mixed in the same 3 ounces as above. 1-1/2 tsp Epsom salt.

Use Seachem Flourish Excel, and dose the lower amount on the label every other day.

Try this schedule for a week or two, and keep on testing the water with all the tests you have. Lets see also how the plants do with these amounts.

Update and what to do going forward.

Update and what to do going forward.

Dosing schedule was as above and only those things mentioned on those days. Excel dosing was actually less Mil than recommended cause last time it seemed to cause problems. There has been some new growth just beginning recently on a few plants. Three MTS and Elodea added last week. Some new plants Hornwort, etc added just days ago. Been reading the Ecology book.

30% water change then,
TDS 375
PH 8.0
AM 0
NI 0
NA 40
dKH 10
dGH 18

Feb 7
TDS 474
PH 8.0
AM 0
NI 0
NA 20
dKH 10
dGH 18
then 15% water change

Feb 14
15% water change then,
TDS 460
PH 8.0
AM 0
NI 0
NA 20

Looks like things are getting stabilized, NO3 at lower levels is good.

How are the new leaves looking?

These 2 plants are the same 2 that grew out yellow leaves earlier. The anubia one dyed off the other grew out fine. Have not seen healthy growth in a long time, forget what it looks like. LOL. Still battling green fuzz algae. The Cryptocoryne new leaves look OK too. Anyway, here are leaf pics.

Sucks...
I go from dosing 1.5ml of Excel every other day to 2ml and in the first 24 hours lost my last cory.
This is a 37 gallon tank! I know this is less Excel than what many use.

This is one reason why I stopped adding anything to my tank.
Every time I have used more than 1.5ml of Excel I have lost a cory or something else.
