Thanks, all. Temp's steady at 78°F, no new additions. I'll check for pests and tweak flow. Alkalinity was 7.5 last test—gonna bump it slowly.

My Zoanthids haven't opened in three days. Tank is a 40-gallon with two Clowns, parameters are 0 ammonia, 0 nitrite, 10 nitrate, salinity at 1.025. Lighting is AI Prime running 8 hours, no recent changes. Any ideas?
