market price for both products are very close too. but for me who keeps both fw and sw aquariums. i would use hydor more for freshwater and tunze seems more specialised for sw. consumers' perception towards the product i would say. though currently i am using a same hydor wavemaker for my sw and fw to see which tank goes down 1st

I have had a sun coral colony for a week now. The weird thing is half the colony opens and half of it stays close. I was able to target feed the half that is open which always waits on me the same timing i feed them each day. What i am worried here is if the other half does not open I believe if they die off the whole colony will be affected. With regards to that the flow and lighting is about the same in the area of the sun coral as they usually come in not too big sizes. Pouring of food juices do not seem to work too. Additional questions include feeding timing before/after/during lights on period to influence the opening of sun corals. Sun corals are not photosynthetic therefore was wondering if any fellow reefers have experiences with lighting intensity that can affect their behavior. Same ideas for fragging them which is not advised from what i read. Do share your experiences! Regards
