FAQ: I was planning on setting up an aquarium for dwarf seahorses. Does Seachem Reef Dip™ protect against hydroids? Or do you have any suggestions on a different product I should use?

A: First of all I have heard many different opinions about using live rock with dwarfs due to hydroids (this is a very broad description, the cnidarians include thousands of species). You may want to consider using "dead" rock and a little time to start your own biological system naturally. Reef dip™ would not be an effective practice in this situation. It is used mainly to combat bacterial and protozoa infections.

I would definitely err on the side of caution and wouldn't introduce anything else to the system that might pose a threat. If you still want to add macro algaes and I would be sure to rinse very well and inspect new specimens, very carefully. Please keep in mind that this is not a guarantee to rid hydroids because even after many precautions hyrdoids can still infect a tank.
