Glosso leaves turning yellow - need help!!
I have an 140 Gallon tank with Igwami Concept. I have done carpeting with glosso. It has been 1 month since the setup is in place. all this while I have had lovely growth and spread... Since last week 10% of the glosso in a scattered pattern are turning yellow, pale and mild clear spots in the leaves..
Tanks size - 48 L x 24 W X 30 H
Lights - T5 6500 k, 54W x 4 nos. T5 12000 k, 54W x 4 nos
Co2 - Full fledged kit with Beetle diffuser. 5 bps. Co2 - 20-30ppm.
Water change - Weekly 20%
50-60 fishes + 100 RCS.
Lights - 7 hours
The second concern - I don't see more than 40 RCS at any given time. I saw atleast 15-20 of the females berried since last 2 weeks..I doubt if someone within the tank is snacking on them...I have 15 cardinals, 30 neon tetras, 20 Neon Rainbows, 2 female black mollies and two small siamese algae eaters.
