So I was and still may looking at getting reef breeders photon 16 for my 22x22x15 I think that is the height might be 18. But I have talked to alot of people who are very satisfied with kessils and the look is more sleek than the reef builders. Life happens and I had to put the upgrade on hold but next month I get paid three times so I am getting them, so long as nothing unexpected pops up. what what am really wondering is the par on the a160s I dont have a very deep tank so im not too worried but I still would like to make sure they will grow sps well.
