It’s not like us to single out a frag plug for review but since we’ve been doing a lot of LPS coral fragging in the last few weeks, we’ve found ourselves reaching for the Lighthouse Aquatics frag stones more and more. With a bucket of various coral cradles, plugs, tiles, aragocrete, plastic, ceramic and even resin coral frag mounts at our disposal, our fishroom is a veritable museum of commercially available plugs. We were reaching for the frag stones instinctively and before understanding the reasons why, we realized that we had really come to love what appears to be just another frag plug. After further scrutiny, we realized that the frag stones are more solid than the commonest aragocrete flavored plugs. The surface of the LA frag stones is very rough but the interior is not porous, and therefore does not trap detritus and crud which can lead to localized algae growth. The bottom of the stones is flat, and weighing in at an average of one ounce/28 grams each, the LA frag stones have enough mass to hold up much larger coral frags. This is particulalry noticeable with Euphyllia and Duncans which can inflate their polyps to a great degree and start catching a lot of flow. Finally, the large impression in the center of the LA frag stone is well sized for gluing down frags of large branching LPS. Lighthouse Aquatics frag stones are not for the high volume coral fragger but if you find yourself occasionally mounting larger than average frags of SPS and LPS corals, you ought to give the LA frag stones a try.
