I’ll add some more leaves and cover for any fry that may hatch out, leave the female in and lower the conductivity with successive water changes with RO treated with humic substances over the next few days to 50µS. If this current clutch of eggs makes it great, if not, there will be proper conditions for any subsequent spawns.
To create paro suitable water for water changes, I have been using an internal filter filled with a mixture of organic acidic materials placed in a separate container to treat RO water + a slight amount of tap water to facilitate ion exchange. It works much better than the ‘boiling of materials to make a tea which is added to water’ method. This new method results in a quick reduction of acidity to about pH 5.0 and only a mild tingeing of the water – some humic substances, but not so much that the fish become unobservable – thank you Bernd and Pavel for the water treatment recommendations 🙂 .
