I have a small 6 gallon nano reef tank that’s relatively new (about a month old) and the hammer coral started opening it’s mouth 2 days ago and now it’s starting to expel its algae. I did a water change and checked levels to see if everything was fine. The nitrite is still a little higher than usual but nothing that won’t correct itself. The only other issue I can possibly see is the water heater I have. I currently have an aqueon 50W heater placed in the back near the hammers. Should I remove it or is it fine to keep in? Also what else can I do to help hammer recover?
