Hi everyone, I am getting ready to change my dual power compact bulbs. I have LR, fish, inverts, and corals. My question is: do I change all the bulbs at once or do I change one and do another a few days later?
when i had pc's i changed them both at the say time but many will say one set at a time... i personnally doint think it's needed since one set are accetenics..
