I've been slowly raising alk in my tank also, since I've started adding SPS to the mix. If you're having trouble finding spots for those frags, I still have plenty of space in my tank. Just offering to help... lol!Thanks! Not much has been going on in this tank. I've been slowly raising my dKh to somewhere closer to 9, since my SPS weren't growing much. The increased alk is already affecting the growth. I still need to place those frags I got a few weeks ago.
