Hi everyone. I just began setting up a new 90 gal. saltwater tank. I have a built-in overflow with a Sealife Systems Premier 150 wet/dry filter. I just added 80 lbs of aragonite sand (not live) and salt water. As can be expected, my water is very cloudy and has been for about 36 hours now. I am running my protein skimmer, which has quit pulling anything out of the water, and I have a 3"x3" foam block and a cheap poly-type filter pad in the filter. My question is, what type of filter media is best to polish my water and should I always use it, or just until my water has cleared? I rinsed the sand before I added it and it has cleared up a lot but it is still cloudy. Any other suggestions about setting up a new tank would also be appreciated. Thanks.
