oh nice i did too i used dry play sand rinsed it about ten times. How many times did you rinse the sand before you put it in the tank since that will be a lot of sand in the.
Yeah with that much sand your better off rinsing it more times but it will eventually settle just going to have a lot of loose sand for a while. But nice tank i have a 125gallon as well idk what sand or maybe rock im going to use
