what deficiency in my tonina

[scang7]

Hi,

I thought the deficiency that i had on my tonina were due to a lack of potassium. But as i increase the amount of K in my tank, There don't seemed to be much change... can someone help?

fertilization regime
1. 5ml of seachem fluorish
2. 1/8 tsp of K2NO3
3. 0.9ppm of Phosphate
4. 4ppm of K from k2SO4

tank parameter
25C, 9 hrs of lightings with 76W for a 2ft tank and pressurized CO2. CO2 level in 20-30ppm

Thanks

You have loads of light and yet only adding the fertilizers once per week?
Try to add the stuff 2-3x per week. You do not need to add K2SO4 if you are adding the normal dose of KNO3.

Hi Peter,

Sorry for the mistake. I am dosing the current regime twice a week. I have actually conversed with you thru email not too long ago. Tried going for 3 times a week cos of the growth that i saw in my plants after trying your recommendation but algae boom esp after i trimmed my hair grass. so back to twice a week now.

Deficiency shows on more leaves after i stop my regime of K2SO4. But dun seemed to decrease much after some dose.

Is the deficiency in the picture most likely due to lack of K?

I don't keep tabs on people so I may forget a thing or two very quickly... :P Are you the one with a pretty high bioload or is it someone else? Is the plant biomass very low at the moment? Things can go sour very quickly if you somehow drop the plant biomass too low and have high fish load. The K has nothing to do with the plants situation at all. There is more than enough K in the KNO3 dosing unless you cut back alot on it. I simply go back to the same old routine I suggest for you.

Prune away the algae affected leaves.
Give the tank walls a good scrub down and clean the filter.
Do a large 60-70% water change.
Check and double check the CO2 levels for a couple of days and make sure it stays in the good range. Check your equipment also if it is in need of a calibration.
Dose the nutrients 2x per week and later 3x once the plants grow in.
Avoid massive prunning and if necessary, add in plants like hornwort to stablize things till the plants grow in.

If you want to improve things faster, you can do the scrubbing down of the tank 2x a week and add back nutrients after that. Keep a close eye on the CO2 and make sure the GH does not drop below 3.

IME with Tonina sp., the plant seemed to be quite hungry for NO3. The plant seemed to react positively with increase dosing of NO3. You might want to up the NO3 more and see how your plant react.

hi...

my bioload is about 20 espei rasbora, 5 dwarf pencil fish and 5 otos... should be alright for a 2ft tank rite?

so do you sugeest that i should increase the KNO3 from 1/8 tsp to maybe a quarter.. in that case do i need to increase any other fert for that increase?

thanks

Maybe you can up the dosage after water change to 1/4 tsp. Observe for the response and adjust accordingly.

Just keep the rest constant at the moment.

Hi,

The toninas seemed to be the same after the dosage of extra NO3 but perhaps it's still early to tell. The new branches from it seemed to be growing faster and looks green...

BBA still quite a headache in my tank. Growing on the front inche of substrate. have to pick it quite often... checked my Co2 level...seemed to be alrite but crank it a little more... is there anything amiss in my dosage?
the only thing change from my last posting is the increase of NO3 from 1/8 tsp to 1/4. (tsp = 0.5ml?)

The plants seemed to be growing well other than the toninas..... thanks

I purchased a bunch of about 10 stalk of Tonina that cost me 6$ a week ago. It dont seems to be growing. I had my KN03, P04, Seachem Florish, Trace, crank in lot of C02 but it still wouldnt grow any taller. Two days ago, i added some SALT to kill the White Spot on my Tetra, this morning i saw a few Yamatos prunching the leaves and when i came back from work, a few stalk are almost bota. Immediatly i check my KN03 and it shows more than 12.5ppm, i quickly change 20% water.
Can anyone guess what is the problem?

Looks like NO3 deficient.
I have this problem before.
Make sure you dose the right amount and be patient.
The plant will not recover overnight. Give it about 2 weeks.

[/quote:a915e2f590]I was told by a fellow hobbyist that he discovered Yamato shrimp munch off Tonina leaves. After he removed those shrimps, the plant strive well. This I'm not sure since I never keep Yamato. Perhaps you can verify it.

I dont think its lack of N03 as my Tetra Test Kit shows about 12.5ppm
-15ppm. And i believe the Yamato will only munch algae and not healty leaves unless the leaves had algae on it.
Still cant solve the problem!
