I want to put a couple hermit crabs in my 29 gallon tank. In researching hermit crabs I keep seeing what looks to be a need to put additaves into the water. Is this the case or would they be fine without special attention?
Calcium and Magnesium are the major elements for reef health.
Iodine and Trace elements are also essential to the health of a reef.
All of these elements are generally replaced with water changes. If you have a high demand reef system (SPS corals), it may be necessary to supplement the tank with Calcium and Magnesium, but otherwise, regular water changes (10% per week) should be enough to maintain the elements at the necessary levels.
Is your 29G full marine or still brackish? Hermits need full marine to survive.
It is still brakish, 1.015. I plan to raise it to full marine though. Then I would like some hermits.
Thanks, I was confused. I havent gotten into coral yet so a lot of the chemistry stuff I havent got a clue..
