Right... Not a great way to start the new year.
The wood i added (well, assuming it's the wood!) has leeched something into the water and has left me with
THREE DEAD GEOPHAGUS PELLEGRINI and
ONE DEAD SHOVELNOSE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Words cannot begin to describe how angry i am!!
The wood was scrubbed and soaked for a couple of hours before i added it. (Added yesterday afternoon) The water didn't seem too bad that came off of the wood so i decided to add it. The water this morning was super cloudy and stained yellow. Was labelled as Sumatran wood, which i have in all 3 of my other tanks and prompted me to get it again.
Luckily enough i managed to save my Oscar and Sev along with the Plec and Rainbow Snakehead. I thought i was going to lose the Oscar as he didn't look very good at all.

Syphoned some water from another tank into two buckets and put two fish in each. I then proceeded to empty the tank with 3 5 gallon barrels. Checked on the the Oscar and he was laid on his side in the bucket seemingly on his last legs (fins!) I carried on with the water removal and then set about refilling it. Made sure the temperature was similar and added the fish back in. The Snakehead has gone into hiding which is pretty normal and the Plec, Green Sev and Oscar are seemingly recovering (the Sev and Plec seemed fine all along tbh, just showing signs of their stress colours) a little now and swimming around more.
Tank lights are off now and will check on them every hour. Will also do another water change later on just to ensure everything is fine and will test the water too.
Didn't have time to test the water as it was all systems go when i saw what had happened. In hindsight i guess i should have saved some in a glass to test afterwards.
Just to add, a 50% water change was done on Thursday evening and the stats are always good. Usually 0 amonnia, 0 nitrite and around 10-20ppm nitrate. Ph is roughly 6.8
Very peeved and upset. I guess this thread is kind of over as i don't really feel like keeping any fish what so ever atm.
