I didn’t think there was such a thing as too much light, so I’ve been running my single strip PC for about 2-3 hours a day. However I tried moving them to the bottom of the tank with the single strip totally off, and the Colt did a LOT better, but that’s not where I want it at all, so they’re all back to their original spots. The Toadstool still didn’t open up even when at the bottom of the tank with the others. So, while they aren’t melting, or COMPLETELY shriveled up, they aren’t looking like they should either.
