Hi all.
It seems that i have little problem due to Ph fluctuation as i inject Co2 to my Buce tank with inert substrate.. almost every day i see couple of lost leafs.
My TDS is between 170- 200 using Salty shrimp gh/kh aiming for Gh around 5-6 and Kh 2-3.
What are you guy's using to remineralized your RO water for your tank with inert substrate and pressurized Co2.
Any recommendation please ??

I'm interested to understand how the ph fluctuation is the cause.
Actually its my only guess.
There is no other issues in my rank.. no fish or shrimp death occurred.
No algae issue as well.
I also use tropica specialized as fertilizers every other day in small quantities.
My tank showing stable parameters all the time but my guess is that the buce don't like this fluctuation of the Ph between 6 when there is co2 injected to the tank toward 7+ when it turned off.
I had better results once i use active substrate as the water was more stable in the acidic range. But i don't want to use active substrate right now! I don't want to rescape the tank again.
Thanks

pH isn't causing your plants to struggle. More than likely it's the "small quantities" of Tropica Specialised that you're adding. You're using CO2 with what looks like a decent amount of light along with an inert substrate. Tropica Specialized, although it's an all in one fertilizer, is pretty lean. If you're not using the amount that's recommended on the bottle than I would try that amount for a couple of weeks at least. If you're using the recommended amount then I would double it. That is all assuming that your CO2 is adequate. If it isn't then your plants are going to struggle no matter how much you fertilize them.

So, get your CO2 in line, fertilize adequately for the amount of light and plant mass that you have.

More info would really be helpful though such as exactly how much Tropica Specialized your adding. How much CO2 your adding based on your pH with the addition of CO2 versus your degassed pH and some idea of how much light you have going.

Thanks for your replay.
We're talking here about low demanding plants like buce and anubia which doesn't require that much of every thing.
We can see very healthy plants in low tech tanks.. so Im assuming that i have adequate nutrition, light and co2.
With my drop check showing green, the light is about 30% of 45 watt which is low to medium and every day i drop about 1ml of tropica fertilizers and 1 ml of seachem excel .. sometimes i drop 1 ml of another micro nutrition.
I used to have this plants with almost no use of fertilizers at all and the plants didn't suffer at all.
My concern is because when i use salty shrimp gh/kh the ph of the water jump to 7.5 maybe 8 and start to drop to 6.
I remineralized to achieve 5-6 gh and 2-3 kh with tds around 170 ppm.
