Yippie!! Reptiles and Fishies!
Anyone know why the leaves of my E.stellata is curling?? i have no algae issues and my Co2 should be correct...i only get spot algae issues like once a month..so i presume the water is okay....is it because the KH is too high?? the last time i tested it was 7-8. Below is my tank stats...strangely enough...ku jing chao just cant thrive in this tank..
i'm dosing phosphate to make it 1-1.25 during water change..then half the dosage again at mid week..

No. of Hours your light is on: 12
CO2 Injection Rate (bps) : 2 bubbles per sec
Type of CO2 (DIY/Liquid/Tank) : External tank with solenoid
Method of Injection (e.g. Diffusor/Reactor): internal reactor W one ball
Substrate Used : Got from Teo..the brown bags..is this lapis?
How Thick is your base fert : 2cm
How thick is your gravel : 3cm
Liquid Fertilizers Used : LGA and LGM
Frequency of fertilization : 4ml (+4drop LGM) Once during 30-50% water changes and then 2ml (+2 drop LGM) during mid week.
Tank Temperature : 26 celcius
Type of Filter (overhead/internal/canister) : Canister Eheim Ecco
Filter media used : Biofilter/wool/MR. Aqua filter media/ porus balls??
How long has your tank been set up : Since October 2004
Chemical Properties (Fill what you can)

Carbonate Hardness (kh): 7-8
Total Hardness (gH): ??
PH : 6.6-.67
NH4 (ppm): 0
NO2 (ppm): 0?? i know its super low
NO3 (ppm): 1-2?? also super low
PO4 (ppm): ??
Fe (ppm)?

Anyone knows?
NO3...too low. Working with that lean NO3 is asking for trouble. Plants uptake varies over the week (they tend to take more nutrients as the plant mass increases) and plants will slow down/stunt/shutdown its mechanism if you run out of NO3 or any form of nutrients.

could be due to your high K, have heard from several people with same problem with high K. You might want to reduce and observe

AIYO..so sorry simon and peter...thanks for the reply....the thing is its not that low...i mean i made a mistake....using the calculator by juggler (K.F.) for LGA and LGM here are the chemical properties in the water weekly..
Daily ppm Weekly ppm Total
N 0.50379 3.52653
NO3 2.23107 15.61750
K 3.62884 25.40189
S 1.16961 8.18730
Mg 0.20646 1.44519
Fe EDTA 0.19268 1.34874
Mn 0.06289 0.44024
B 0.02373 0.16611
Zn 0.00862 0.06035
Cu 0.00269 0.01884
Mo 0.00278 0.01943
this is just for 4 drops LGM and 4ml LGA....in midweek i also got put 2 drops LGM and 2ml LGA....so i think should be okay... been doing this regime for 4-5 weeks liao..dont know why leaves still curl...
Kasselman has noted this unexplained problem with Stellata in her book too. I guess you are not alone.

ouch!just trying
Ranmasatome, if all fails, change the plant
Yippie!! Reptiles and Fishies!
Wah...so mysterious...i'm going to try all sorts of things the moment i get the rarer plants out of this tank...like over dose purposely or add less k or change kh...but one thing at a time....probably going to take months..lol
actually, i also had this problem. but after i added calcium, the stellata's leaves become better, not curling anymore. maybe u want to try it. i use Seachem Calcium (powder), but don't ask me the dosage. i just dose a bit (0.25ml) for my 5ft tank (trial & error)
Yippie!! Reptiles and Fishies!
Calcium?? ok...maybe that'll be the first parameter i change...
Calcium is only a micro nutrient required by plants. It is not one of the main nutrients. I think it is better to heed Peter's advice on increasing NO3. I think up until now, he tends to be "spot on" on plant growth problem. Of course, CO2 and light must be in abundance before you start playing on NO3 since excessive amount will lead to algae boom easily.
Cheers!
Peter was right, I can grow this plant consistantly and well.
Most of the folks in our groups can.
NO3.......
Add more KNO3.
You need 10-20ppm or so.
K has been very high in past tanks, no issues noted, his is with lower GH's, 5 or less to 3.
It's a fast growing weed and needs fed.
Kasselmann needs to figure out how to consistently grow it, then she'll know why it does well and other folks it does not. Then go back and repeat it. This is easy to do once you know how to grow it, let the NO3 run, or like many folks....forget to add enough KNO3.........
Then it stunts, add it consistenly with CO2/PO4 etc and it does not.
GH/PO4/Traces/KNO4 are all easy enough to add.
CO2 is the hardest variable and also the cause of more issues than any other for most folks.

thanks for the help..i think the co2 and light are enough...so now i guess i'll just play around with the other parameters...but one at a time...but right now the top 3 to vary would be NO3, K and calcium...see if the myths are true...everything else i will TRY to keep constant.
Calcium is only a micro nutrient required by plants. It is not one of the main nutrients.
Does having it in the wrong ratio's cause problems though? This is a common problem that we've been trying to find a solution for, read through this,
