Hello to All, I just setup my first 55 gal tank on Christmas Eve for my son. The setup started at 11 pm and I finished at 2am. The tank - 1 bag of live sand and 2 other bags recommended by my local dealer. I also have about 20 lbs live rock in the tank. I made a mix of 10 gal saltwater the day before setup. I put the live rock in first and then added the 2 bags of sand, in went the 10 gal of premixed saltwater, I then added the bag of live sand and arranged sand and rock for first fitting (you know when the wife sees it she will want to rearrange differently). I then added 45 gallons of Deer Park Water, and discovered that I was supposed to rinse one of the bags of sand to keep the dust down so it would not make the tank look like a milk shake, Ok I made a mistake and I am hoping it all works out, its to late to start over. Ok now I start the pumps, filter (XP2) and heaters up. Now I figured that I should add the recommended amount of salt to get the tank to where it needs to be for salinity. After clean up, I take a quick look at the tank. I notice that its starting to settle down before I go up to catch a quick wink before the kid wakes up. Hoping and praying that the tank clears up in the next couple of hours. Christmas morning tank looking pretty good and I am proud of Santa’s work. I take a salinity reading and it’s off the charts. There are no fish in the tank at this time so I do a 10gallon water exchange keeping the water removed water in 2 new 5 gal buckets for later use if needed. By the time I left for work today the tank was crystal clear and salinity has come down but still way to high. The temp was running high right around 80 F so I adjusted heaters to lower setting. I am going to test the water this evening when I get home to see where I am at. Thanks Gary PS: Any input recommendations helpful hints would be greatly appreciated!
