Well moving things around and getting a new couch so had to move my 72G tank across the room. Did a 75% water change and slid and pushed that big boy and got it moved and change in like I think 30-40 min! Fast! And it looks perfect where it is now...where I originally wanted to put it.
Cleaned out the cover of Salvinia Minima and Duck Weed in the 72G...needing to take that over to the Koi pond for the fish to eat.
Added water to the 37G.
Saw my 6 Otos so they are all there (minus the one that got stuck in the Gobys mouth. He is seemingly doing just fine too after the incident.)
That was the good. Now the bad...
Noticed a little grey white patch on one of the Otos backs and a fat lip on one of the blue Cochu Tetras so I will try treating the Maracyn 2 when I get home tonight from work or in the morning. I am off work for 2 days and can monitor the tank, a little unsure/nervous after the pH crash last time. But hopefully everything will go fine. And I can get rid of this nuisance illness in the tank.
I need to get this fixed so I can condense/move my healthy fish out of the 37G into the 72G and rehome some of them and the 37G tank.
