40GallonReef Posted November 7, 2011 Share Posted November 7, 2011 So I have a 40 gallon DT and a 40 gallon sump, with a total water volume of about 55 gallons. I have a 2 inch sand bed, I do a 5 gallon water change a week. Should I be vacuuming my sand bed out when I do water changed. It is hard to vacuum the sand bed when doing such a small water change. If I leave my sand bed undisturbed, will I eventually get a tank crash? I hope to switch to a new tank in a few months (my tank is scratched), I was thinking of doing a DSB in my new tank. Any opinions on this? Link to comment Share on other sites More sharing options...
Burningbaal Posted November 8, 2011 Share Posted November 8, 2011 get sand sifters. chestnut snail (from garret), sand sifting star, diamond goby, cucumber, etc. if you have critters moving the sand bed around they will eat the detritus/etc and avoid the nutrient build-up.

impur Posted November 8, 2011 Share Posted November 8, 2011 Nassarius snails are my favorite for this. They bury themselves in the sand during the day, or until food is present. They definitely keep your sand stirred up, and its like watching an undead army come to life when they all come up at the first sign of food. Cerith snails also do a bit of sifting, and my tigertail cucumber as well. Link to comment Share on other sites More sharing options...

40GallonReef Posted November 8, 2011 Author Share Posted November 8, 2011 Ok good. I have a sand sifting star fish, 8 Nass snails, a conch, a tiger tail cucumber, and some hermits. I also have a horseshoe crab that does a pretty good job at moving sand. Thank you guys. Link to comment Share on other sites More sharing options...
Burningbaal Posted November 8, 2011 Share Posted November 8, 2011 sounds like you're doing pretty well. Garret will always hook you up right if you need more, esp for the inverts. love my chestnut snail from him! Link to comment Share on other sites More sharing options...
