Is there any rock that looks like lava rock that is not suitable for the aquarium?
Yesterday I pulled out a large crypt from my 75 gallon tank. This stirred up the subtrate a good bit due to the extensive root system. I did about a 60% water change immediately after. I also added some lava rock I puchased from my LFS. I used Kordon Amquel for a dechlorinator because I ran out of seachem prime and my LFS carries Amquel.
Any way all was well until this morning I woke up to a dead flying fox and about 4 dead shrimp. All my snails were heading to the top of the tank. I tested for ammonia thinking disturbing the substrate may be the culprit but there was next to none. Certainly not a level that would harm my fish or shrimp. I did another emergency water change. This afternoon there were more dead shrimp and the fish snails and shrimp gasping at the top of the tank. I did another water change. Tonight same deal some dead shrimp and from the looks of it soon to be dead tetras and everyone up top. I finally pulled the lava rock out but I am out of dechlorinator again so I can't do a WC. I have a powerhead rippling the top of the water for aeration. The filter appears to be working fine. What in the world could be going on? Did I get some seriously bad lava rock.
What in the world could be so toxic to still be a problem through 3 water changes and in a heavily planted tank.
I am assuming much of my livestock is doomed. Luckily I only had a few fish in there. A lotta cherries though. It's a shame.
