haven't updated in awhile so here goes. WP40 is performing wonderfully. I think the intial stress from the yellow tang experience had made the purple tang sick (noticed a whitish powder on her body) so I first removed the purple for about 1.5 weeks. treated with copper. got her back to health and had to add her to the tank again because I believe the confines of the 10g qt tank were slightly adding to her stress. shes been eating like a crazed lunatic and been active since adding back in. only downside? im back to square one with the yellow/purple tang relationship. so as of this moment the yellow is now in the 10g, along with the mandarin and damsels. mandarin is going back in the dt tn and the yellow will follow on Monday, when im off work. the BM curve 7 skimmer is getting better and better every week. the color and smell of the skimmate is getting darker and worse with each cleaning. I am planning on adding the auto cleaning neck feature here soon. I have also glued each individual coral to its own little rock, in the hopes that I can get them to spread onto the rock. oh and lastly, I ordered 2 6500k bulbs for my dt. (im only running 2 bulbs atm. I discussed it with a few other hobbyists, including my friend that gave me the corals, and we are in agreeance that 4-96w PC bulbs should sufficiently light these particular frags. as an added step, I will be positioning these frags about 75% up towards the top, if they were to begin bleaching (which prob isn't going to happen) ill move them down.
