The tank is still on a 4-5% daily water change. I have not been using dechlorinator because anything in the tap water would instantly be diluted by 20 times.
I have also added some Indian almond leaves to add a black water effect and a couple new pieces of oak. The plecos have made a good job of munching through it, especially the rusty pleco (Hypostomus cochliodon), who are one of the “true” wood eaters.
The Amazon sword (Echinodorus bleheri) has moved forward, so it is now more visible. I am also trying to grow a few cuttings, towards the front of the tank.
