I switched to LiveAquaria Reef Salt from Marin Tropic Classic largely due to the fact TM is always out of stock plus LA price is reasonable for quality product. Quickly mixes clean and clear.
Me too. I've been using the LA salt for 5 months now. Always mixes clean, clear, and leaves no residue.
Watch Petco for sales on the LA salt too. They are sold out right now after having a big sale on it a few weeks ago.
They had the 14# bags on sale for $7.50. You could buy (4) bags or 56#, which essentially equals the 55# box, for $30 with free shipping. I stocked up during that sale. I shake the bags up real good and then dump them into a bucket. You can then roll the bucket around to mix even further if you want, but I haven't found that to be necessary. The LA salt has been consistent for me whether it comes out of the bucket, box, or bag. For the price, I think the LA salt is hard to beat.
