Tired-- Ready to Nuke tank!!!

Blackouts can be really effective. AFAIK, this should do the trick:
Do a water change, then turn off the lights and completely cover the tank with towels, black garbage bags; anything that will block all the light. Cover the top as well if it's glass and light from the room can enter. Leave everything alone - no peeking, no feeding, no nothing for three to five days. Then uncover the tank and do a large water change (the dead algae can cause an ammonia spike). Pretty sure that's all there is to it

Will try this. Running out of ides. It is a 100gal so I will have to make something to cover it.

I assume I will have to turn off CO2.

Cover well, but don't forget to leave some room for ventilation to let the CO2/O2 exchange happen.

Thanks for all ideas. Going to fabric store during week to make a black felt skirt to put over tank. Will post back in a week or two with results. cross fingers
