Have not purchased any ‘thongs’ yet but not ruling that out! I’m building the RedSea reefer 250. 64gal total..53ish in the tank. I’m hoping to get my build thread going later today. Unfortunately work keeps getting in the way. TyYea i spend close to 20-30$ a day usually taking care of my tank. I tend to buy thongs preemptively so i can save a little. What size tank have you put together?
