Saturday morning shrimp were dead laying all on one side of the tank. The fish that were still alive were at the top of the tank trying to breathe fresh air. Shrimps and tons of ramshorns were all also at the top of the water line.
Here is a picture I took last week after removing the hob. I was amazed at how far it has come in the last few months. I ended up losing my L201, 95% of my shrimp and my oldest sterbai. It was very upsetting to see the carnage in the tank Saturday morning. I was able to save a few shrimp including a few babies, my nerite, three sterbais and my beta. They were rehoused between two other tanks. I had to run down to petsmart to grab some hiding places for the rcs shrimp in my edge 6g. My old beta in there thought dinner was coming early on Saturday. I had to remove my danios and ghost shrimp from my edge 6g and move them downstairs to my spec 5g. Quite an ordeal to figure out how to house everything.
Now to why this happened. I'm hoping for input on this. The tank had been running fine with a 30g hob and a foam filter in the tank. I added a canister a week prior. Come Wednesday I figured that the tank had enough bio and with the sponge going in the tank I could take the purigen and bio media from the hob and move to the canister. I checked my water parameters Friday and they were close to normal. Ammonia was .25ppm which for some reason seems to have been the norm since day one with this tank, Nitrites 1ppm and Nitrates 20ppm which have also been the norm. I needed to add water anyways so I also added so added some API safe start. Enough to treat the tank. Did this kick something off overnight? After rehousing Saturday morning I checked the parametres again. Ammonia .25ppm, Nitrites 3ppm and Nitrates 40ppm. Tank water still clear. Saturday afternoon the tank clouded right up and you could see the cycle.
Did removing the hob cause this? I figured relocating the media to the canister would be fine since I still had the foam filter running. Did the API safestart do something?? What did I do wrong??
