I have sand for my softshell...he loves it...but it is difficult to find a good underwater filter system...I have gone through many....sand gets into the pump and they quit....I do have a powerful under the cabinet one....Cascade 1000 plus a whisper 40 for inside the water but the whisper only lasts a short time once the sand gets to it....I have tried various fluvals and they are horrible...any suggestions? Thanks
