Recently overhauled totally my 60ltr. tank. Added Tetra plant sticks in substrate before planting out. There is CO2 injection and I does a general fert. daily. Some plants are OK but others not ie: see pics. of Pog. erectus & Hygro. corymbosa. One thing I've noticed is there is no pearling yet there was in previous set up on Java ferns in particular. Maybe, I need to increase light intensity or period? They've had plenty of time to settle in, so that is discounted in my book. Thanks in advance for any help offered.
