It is like this medicine does nothing
I don't know the medicine you used, but the entire process is just stressful - and also the potency of the meds could be a factor here .
I'm sorry about that. Focus on keeping the other tank healthy, so you can mitigate this in the future - everyone has done something like this ... and we all feel bad about it - keep trekking.
I'll try your ingredients.
Let me know how they go.
It was that bad all my Anuibis Nana melted and died. on the other hand I also need to find an equilibrium as I went Wasltad to get away from constant fiddling and dosing.
The plant may have melted from several factors not only the pH (although those factors may have affected the pH).
The Walstad way is all about equilibrium; she uses dolomitic lime in the substrate but she doesn't have loads of reactive rocks in her tank. I am looking at the front cover and front matter of her book right now and all I see are clay pots and plants
I might try for equilibrium with twice weekly small matched water changes.
This would be a hybridized approach and would basically be in search of "equilibrium with water changes" -- which means if you slack on the water changes (we are all human unless you automate it), then the next water change would have the same TDS shock on the fish - OR you have to play catch up again as you do three that week that are smaller (or some values here that you discern) to drop your pH back.
I'll get a high range PH kit and put heaps of leaves to offset the stones. Hopefully I can get it stable low enough to keep my plants going as they are finally growing nice.
The leaves will deteriorate faster than the rock, so if you slip up on adding more leaves, then you may run into an issue. In small tanks, adding some chunks of almond leaf can plummet the pH quick (or eat your buffer in this case). Your substrate has peat in it, so it is already counteracting the rock.
Thanks everyone for your help, it I'll combine everything said here to get this tank running right. Failing that I'll just have to re-scape it with less troublesome materials. I will keep posting here with the progress too
No problem. Inert stuff is great, but the stone you have is beautiful.
Honestly, I would get the high pH test kit and test your pH throughout the week; continue this until it plateaus - that number is your equilibrium. It may not be as high as you think. By the sounds of it, the rest of your livestock is fine and your plants (aside from the nana) are ok (if they are all melting and dieing, then we need to clean vigorously at this time) - advise me here.
If you want to find the natural equilibrium of the tank, then:
1) cease playing with all chemistry -
(this is a point of contention because if the overall health is declining then we have a sophie's choice - to change or not to change) OR make sure it is as close to identical as the water at the current moment in time - this will be ok.
no more leaves
2) test pH daily/twice a day at the same time and log it.
When it plateaus, we can decide what to do next - are we happy with the pH, or do we want to fiddle more.
