I've setup a breeding rack in the garage basically 100% inspired by the COOP (Cory, Dean, & Randy). Cinder block stand, linear piston pump, dual brine shrimp hatchers, drilled over flows, fry system (the works). Six 20Hs, One 5.5, One 40B, One 75, a 20L (fry system), and a custom built acrylic 50H (craigslist find, 80 bucks, needs to be buffed). 9 tanks in the house, 120g, Three 20s, Three Nanos, and a 4g Cylinder (all heavily planted).
Anyway in the breeding rack, currently two angel pairs (one batch of eggs) both spawning, 100+ E.B. Acara fry, 200+ Praecox fry, Super Reds Bristlenose growing out, Guppies/Swordtails (gravid), Pundamilia Nyererei cichlids (holding eggs). I'm really just try to figure out what I enjoy breeding and eventually specialize in something. I'd give a toe for some midnight rams from Dean but alas I'm on the east coast. AQUASHELLA ORLANDO 2022!
So after the long intro... 🙄 Two of my grow out tanks smell like cyanobacteria, the water gets cloudy after a couple of days, no visible blue/green algae in the tanks. Are there other things that smell like cyano? All of the tanks are cycled, we're 5 months in now. Cycles started with bio from other tanks, over sized Coop sponge filters. The only tanks that have smell and get cloudy are the E.B. Acara grow out (100+) and the Super Red Bristlenose/Praecox. I've added mardel maracyn to one tank for testing, and the other gets daily water changes until I get this figured out, I don't want to risk medicating 100 tiny fry. If anyone has advice I would greatly appreciate the insight.
Sorry for the long post, I'm nerding out heavily in this hobby.
Thank, Andrew D.
