Zoos now closing

[Tom2006]

I had a few lovely zoas that came in on some LR when I first got my tank. They have mutliplied very well since then fully open etc. They are high up in mod flow. However over the last few weeks they have started to close and now very rarely open at all. The only recent changes are that I have added a small hammer frag although its a good 8 inches from the zoas. I have also recently started using ultipos. Could it be either of these factors. I use 4 x 54w t5s. I haven't replaced the white tubes since I got them but they are still only 8 months old and look fine. Any suggestions? Would a FW dip help and if so how do I do it?...tap water or RO water?

Hi Tom,

If you wan't to fw dip then it has to be RO WATER,
But all corals sulk for no real reason this is part and parcel of running a tank lol keep you on your toes IMO your lighting looks fine for softies so its just a case of the waiting game PS how are your perams ?.
