New to the forum. I have been out of reef aquarium keeping for the last 5-6 years. Just wanted to say hello to everyone here. I will be starting a 56 gallon reef tank soon. The tank is not drilled, sadly it's tempered glass and I am unable to just drill it myself. I am still debating whether to use on overflow and sump/refugium or just use hang on back style equipment. Any opinions or pros and cons would be great.
