ammonia is still high...others may disagree but in my opinion having a microalgae within the system while it's cycling won't really do much, then again i can't see the harm in having the algae in there either. if the caulerpa is starting to lose it's coloration or if the tank cycling is taking it's toll on the algae, simply remove it to a seperate holding container until your tank has cycled...
once you add the caulerpa back into the fuge, try to light up the fuge (with a small light on it's own timer) on a reverse photoperiod in relation to your main lights. this will be more than adequate to keep a microalgae and it will help stabilize your PH too. HTH. _________  |
