I cycled by adding a cube of brine shrimp and dr Tim's one and only bacteria every five days until ammonia and nitrite were 0. Added the cured live rock in week 2. Haven't saw any ammonia or nitrite since week 4. Diatoms came and went through week 5. The tank has been up for 5 months now.
Four blue green chromis
Three bangai cardinals
The angel was hanging out in the top back corner the day before and didn't eat but all the others seemed fine. The clowns I've had for months. Angel maybe two months. Cardinals and chromis a month.
The cardinals died first, then the next day all others. I stay on top of the water by checking twice a week and every time I see something acting funny but I don't know what else to check for except the normal parameters.
