Soap can leave a residue that is hard to wash away. Bleach dissipates as it dries. You can also add Prime to destroy bleach. Stay away from soaps.I was told it was ok but to make sure i fully rinsed it because if there was any trace,would kill the seahorses instantly
seahorses are so cool and to loose all of them is so sad. Glad you are hanging in there. Hope all goes well with your new seahorses. When things get better and your seahorses settle in please post a couple of pictures and let us know how things are going.
