Hi Friends,
My frag tank is a 20 gallon all in one. Fully cycled since 2020. I had a fairy wrasse in there along with some snails and emerald crabs and probably 30 frags. Last week, I heard a splash and saw that my Fairy Wrasse jumped out of the tank (yes I know, fish jump and I should have a cover). I put him back in and noticed he was having trouble breathing so I got him out of the tank and but him in my display tank so I could run some tests. Results:
Ammonia: 0
Nitrite: 0
Nitrate: 5
Calcium, Mag, Alk all normal.
After the tests, I noticed the crabs moving very slow or not at all so I removed all the inverts as well. I did a 25% water change and waited overnight.
The next day I notice my corals starting to lose color and retract so I tested parameters again. Nothing unusual. I put a hermit crab in the tank to see if the water was ok and within 5 minutes he had managed to climb his way out of the tank. I removed all the corals and gave them a coral bath and put them in the display tank. Performed a 90% water change. Waited 24 hours and tested the parameters again, nothing unusual. Put in the Hermit crab again and same results, he is climbing out of the tank. Performed another 90% water change. Waited 24 hours and tested the parameters again, nothing unusual. Put in the Hermit crab again and same results, he is climbing out of the tank.
So here I am completely clueless as to what is crashing my tank.
Are there any tests I have missed? Has anyone ever heard of this happening after 2 90% water changes? I fear I will have to tear down the whole tank, wash everything and start a new cycle.
Any advice or questions for me before I tear apart the tank?
Appreciate your support.
