So, I need to remove about 30 fish, including cory cats, from a heavily planted tank so I can do AlgaeFix on it for beard algae and then switch out substrates (basically tear down). Problem is I can't see what I'm doing! The light is so poor because I have to remove the light strip to get into the tank and the water is so cloudy from me stirring up the soil based substrate that I can't see. Should I just leave them in there for the algae treatment (and subsequent mass snail die-off) and hope for the best? I'm most worried about the cory cats since they're so sensitive to chemicals. :/ I've only caught about 6 of the fish I need to get out and none are cories.
Ugh, I feel like just going back to bed.
Remove the plants to the 10g and AlgaeFix in there, let the darn fish swim in their empty cloudy tank until it's time to switch the substrate. What say?
