Hello All, my first post on the forum....exciting !! i am looking to buy a sw aquarium, 46 gallon, with dsb, and liverock, probably 60 lbs... i had a question about the deep sand bed...i am planning on buying the play sand everyone talks about on here from home depot, and was wondering if i dump this right on top of the undergravel filter?? will the sand plug it up?? any suggestions, what about buying live sand from the lfs, from my understanding it really isn't worth the money cause the live rock eventually will turn the sand into lsb. thanks for all the help.
