sorry ar... does the amount of light affect the plate ? cause i have noticed .. when i on all my lights ... the plate shrinks .. to the extend that the centre portions looks dead.... currently running 2 PL .. blue and white.. gonna save for T5 ..
when i off one of them the plate seem to expand alittle ... covering all the base skeleton.. looks pretty healthy. it is currently sitting on very fine sand now, i got them from the beach quite sometime back..
pls advice thanks
