Tank - Marineland 29 gallon
- 20 lbs (Fiji/Brazilian)
Fish - Bicolor angel, tomato clown, 3 damsels and 1 yellow chromis
water parameters - nitrate - 10 ppm
, nitrite - less than 0.2 ppm
- 8.0, ammonia - almost 0
2 weeks back I changed substrate from crushed coral to live sand +play sand combo (20 lbs + 50 lbs respectively).Prior to the change, moved my fishes to a 10 gallon tank with the cycled water. Since the water became cloudy almost milky, I did a major water change (tap water, dechlorinated it and set specific gravity to 1.023) and let the tank run for 2 days after which I introduced my fishes and the cycled water.
Once the water settled, I introduced around 6 lbs LR
The water parameters measured have been taken today.
THis is what has happened -
Diatoms appeared cause all the rocks were covered with brown dust like stuff.
All my fish have died within the last 5 days.
I have been conducting water quality tests throughout the last 2 weeks to make sure everything is ok and levels are really not high. This has always been the case.
Please help, I do not know whats happenin here?
