I'd definitely have no issues getting rid of all that sand that had root tabs in. This thing about loads of beneficial bacteria living in sand is not especially true in all my years of reading around and my personal experience.
Balance is fine, colour is normal, just pretty lethargic. I imagine they're probably still pretty stressed. They're also now in a small group (only 4) but not going to worry about that for now, need to get them through this first.Corries might still be in recovery. Euthanasia might only need to come in if they can't keep their balance, or swim properly. How is their colour?
Thanks. I only moved over to RO originally because I didn't realise I have very hard water when I first got my cories. I also have a betta so will keep using the RO water for his sake as well.I’m sorry about all the problems you’re having…
I’ve gotten away from any chemical additives… no fertilizers, no remineralization of my RO water… I’ve just settled on plants that survive on fish waste, and so far none of my fish have shown me, that they need more minerals, from the water… they get a varied diet… only my Cherry shrimp get straight well water… the Armano shrimp seem to be doing fine in the soft water of my African tank… been thriving for over a year, but they don’t breed in the aquarium, and I’ve not noticed any issues with shedding…
I just don’t trust adding any chemicals to my tanks…
I assume you mean you don’t add artificial chemicals to the tank, technically water is a chemical. Are rift lake salts unnatural?I just don’t trust adding any chemicals to my tanks…
I think I will give that a go, and just be much more stringent about my testing. I think I had finally got to a place where I felt confident enough not to need to test all the time as I thought I knew my tank quite well. I know some people don't test but I think for me, especially after this, it will give me a little more confidence.Going forwards, you could try mixing plain RO water with your hard tap water to get the hardness you need. That would leave some minerals from your tap water in the mix.
Yes that is what I do with my RO/DI water. I mix a 60/40 (RO/tap) ratio in the aquarium. I remove the water from my tank and then I add Seachem Prime dosage for the total volume of the tank. I add the amount of tap water to my tank, then I add the RO/DI water to fill the remainder of the tank.Going forwards, you could try mixing plain RO water with your hard tap water to get the hardness you need.

Potentially a silly question but adding in this way doesn't upset the fish at all?Yes that is what I do with my RO/DI water. I mix a 60/40 (RO/tap) ratio in the aquarium.

I stopped mixing tap water directly into my RO/DI holding tank in order to prevent the tap water nutrients from causing biofilm buildup in the holding tank. Keeping just RO/DI water in the holding tank eliminates the biofilm buildup issue I was experiencing previously.
