Any update on the plants? Are they doing any better?

If so what were the dosing changes that worked?

Hello Zapins and thank you for your interest.

Sadly, I am an impatient person. I started doing too many changes and have recently changed my regime once again.

I will be doing the following for the next two weeks and see if there's any positive change to the tank's current condition.

After water change on Fridays I will add:

.75 tsp of K2SO4 (12.6 ppm of K)

I will not add any GH booster since my tap waters GH is 8-9 degrees.

Macros: Sat-Mon-Wed

1 smidgen of KH2PO4 (.711 ppm)

.25 tsp K2SO4 (4.1 ppm of K)

1/8" tsp KNO3 ( 2.34 ppm of nitrates and 1.47 of K)

Micros: SUN-TUE-THU

CSM+B solution dosing .05 FE

And 1 smidgen of DTPA 10+ to get .15 ppm of Fe

Total amount dosed in a week:

Fe : .6 ppm
N: 7.02 ppm
P: 2.133 ppm
K: 29.31


I will definitely stick to this dose this time to see the effects on the plants.

I assume the total amount for each fert is more than enough for a heavily planted tank.



I will update later in the day with pictures.

Im sorry for not keeping up with the thread and thank you all for the interest.

Cristian

Looks like a much better regime to me!

You are adding a massive amount of micros. The dosage we recommend for a solution of CSM made with a ratio of 1/4 cup dry CSM to 2 cups water is 1-4 drops per gallon of tank water per day. There are 75 drops in a teaspoon. You want to start out with the smaller dose of 1-2 drops per gallon per day. Then watch the plants and see how they respond. Increase the dose only if the plants tell you they want more after 2-4 weeks. Plants are pretty slow to show the changes.
I am not very good with all this measuring and testing but not looking at the plants. I would back off with all the fertilizers to about half and wait to see how the plants do. Look at the plants to see if the problem is structural as in cell production and strength which means they are deficient in macros. Or if what is going on is physiological as in production of chlorophyll. Although you have some red plants, you probably do not need a lot of extra iron.

0.6 ppm traces isn't that high. Above 2 ppm and we get into toxicity levels.

I might raise nitrates a bit 7 ppm may be a bit low in the long run.

Default Help identifying deficiency or toxicity...

I'm back at it again...



I recently purchased a calcium salifert test kit and tested my tap's water Ca concentration. My findings could be the cause of my twisted and maybe stunted growth.

GH: 8 degrees which is roughly 142.7 ppm (using API test kit)

Ca: 60ppm (using salifert test kit)

So,

Mg: 82.7 ppm

I suspect this being the reason for twisted and possibly stunted growth.

Will adding more calcium to have that 3 Ca : 1 Mg ratio be okay?

I've also read somewhere that there is no magic ratio.

Perhaps you guys can give your input on that as well.

What's considered high for Ca and Mg?

In my case, will adding more Ca to have that 3:1 ration be safe? Or will I be adding way too much calcium?

Thank you.

Thanks.

That ratio is fine, a lot of spanish aquascapers preach that the best ratio is the otherway around. 3-4 times as much magnesium. So anything from 7:1 to 1:4 is fine.

Thank you Johan. So, according to my tap water's parameter, there is no need for me to be add more Mg or Ca.

I'll test back again at the end of the week prior to a water change to see if it went down at all.

Thanks.

No, both are high enough and the ratio is still normal. CSM contains magnesium, but in small amounts.

Thanks.

Another question:

Last trip to my LFS the owner told me that when using APIs Nitrate test kit, to divide the result by 4.4 to get my correct reading.

Is this correct?

Something to do with total nitrogen vs nitrate- nitrogen

So, if my reading is 80ppm, then if we divide that by 4.4, we get 18.2 ppm nitrates

Not sure how to interpret API nitrate test kit.

Thanks
