first off, i completely understand that store credit really really doesn't allow you to breathe again about this whole situation like a full money refund on your credit card or checking account would. cuz like you said, it means to make up for all of this, you have to order something again, and now with multiple shipments coming like this, i'm sure your faith is a little diminished to say the least.
like eswebster said, it's not about us though, it is about you and LA themselves. i have never ordered from them but have only heard good things especially regarding their customer service, and obviously they wouldn't still be this successful if they did not take care of problems that arise in a fair and timely manner. that being said, IMO the scoly has a great chance to recover, especially in an established, flourishing, and successful reef tank like yours. it will need some lovin, but it will get there. but because of the state of it, a half refund would be fair to both sides i think. either way i wish u the best of luck, and i know it will be solved in the end. as for the acros, i say why not give them a chance. worst that can happen is they don't make it at all but at least u tried and did all you could. take care and keep us posted!
