Help with plant nutrient problem plz

Post by FuglyDragon »

I realise this a bit outside the scope of these forums but I am hopeing some planted tank experts may be able to help me out with the following problem

Anubias barteri v nana being grown emerged in a plant only situation (ie no fish).
Water is dosed with PMDD mix, dKH is around 6, ph6.8-7.0 depending on the CO2, DIY CO2 injection temp 23 celcius, plenty of light.

the anubus (and only the anubus) are showing brown patches on the leaves as follows.

I have noticed that new growth often comes in slightly crinkly/wrinkled.

About 10 days ago i removed all effected leaves and as you can see the problem has come straight back again.

The frustrateing thing is that other plants in adjacent tubs (with same water, it circulates through 3 tubs, are doing fine)

Any Planted tank experts got any ideas as to what the problem is ???

Po4 around .5
NO3 around 10ppm
FE around 0.2
dKH 6
PH 6.8-7.0 depending on how strong the CO2 is.
I use baking Soda to raise the dKH from 3 (tap) to 6
My PMDD contains Trace,K2SO4,KNO3,Magnesium sulphate,Pottasium phosphate.

Only thing I can think of is calcium, but with a dKH of 6 shouldnt the calcium be ok ???

While hardly an expert on aquatics, I have won several blue ribbons at the MA., horticultural show.
If these were terrestrial plants I'd increase the iron. Now My buddy old LOTSOFFISH would tell ya just to put a bumch fish in there as they will provide almost everything else a plant needs. 8)

Same Issue

Post by hfjacinto »

I had the same issue, an increase in iron and the addition of phosphate solved the problem.

Just be careful with phosphate as you can get an algae bloom if you overdose.

If you use water conditioners, many remove heavy metals (iron included) so dose with iron a day after water change or adding conditioners.
Enjoying the hobby
