I am gonna keep the height of 24" from substrate that I have, may play around with having the lights on cycles of 50% to 100% throughout the 8 hour photo period.
So on to my other problems. I took 3 amanos out of my 120gallon discus biotope yesterday. Acclimated them and they were eating algae like crazy all day. Last night all 3 managed to crawl out of my tank and die.
The water line is about an inch, guess it's not far enough. My water parameters are zero ammonia and nitrite. The tank is def cycled.
The C02 drop checker is green, ph was 6.5 or so on a c02 controller.
I am going to drop the ph today to 5.5 and get a lot more c02 in the water to combat the algae and really hoping to see some new growth from the HC.
Only thing that I could think of as reasoning for crawling out is:
1: Being a new tank to them they thought maybe there was water on the other side and they all just followed each other out, happily.
2: I have no heater on the tank, the water fluctuates between 72-76 day to night from what I am seeing. The room the tank is in receives indirect sun and gets warm. I didn't think that temp change would bother them. It changes over several hours not within minutes.
