I screwed up my mix changed yeast and it was much stronger anyway boiled over in my main set of tanks was less than 1hr(checked it) but noticed the smell in the room before I saw it.
I pulled the u-tube to the other tanks shut off the intake valve.Did a 80% water change on that tank.30% on the main system (tank contaminated has very low flow to others but does)
6hrs latter every thing cool.I also added some good carbon to my overflow box.
Anything else I should do or worry about the contaminated tank is running back on the main system now dont realy want to do another water change as I'll have a bloom did my big change 3 days ago
Honestly dont think much got in the tank but very worried ALL my cool fish are in there.
