theaccordmaniac Posted February 17, 2007 Share Posted February 17, 2007 Would like to find out what is the ideal height for DSB? Quote Link to comment Share on other sites More sharing options...
mansiz Posted February 17, 2007 Share Posted February 17, 2007 Ideal height is 6cm. Don't stir it once establish. Don't add any sand digging LS too. Quote Link to comment Share on other sites More sharing options...
SRC Member iantoh Posted February 17, 2007 SRC Member Share Posted February 17, 2007 hi there theaccordmania, the recommended depth for a deep sand bed is between 3 to 4 inches, preferably with fine oolithic sand. Quote My Goniopora Nano! Link to comment Share on other sites More sharing options...
blueheaven Posted February 18, 2007 Share Posted February 18, 2007 Yep like Ian said, the recommended (or at least that's what most reefers use) depth is between 3-4 inches. Do take note of providing oxygen rich water circulating around the sandbed if you're using very fine sand as you don't want totally anaerobic spots. The bacteria that convert nitrate to nitrogen gas occur in aerobic and anaerobic regions since they are facultative but the process of producing nitrogen gas would be in regions of around 0.5ppm oxygen if I'm not wrong and the process that happens in totally anaerobic regions would be the production of ammonium which is an even more potent nutrient for algal growth Quote But if you tame me, we shall need each other.

SRC Member big_ben102000 Posted February 18, 2007 SRC Member Share Posted February 18, 2007 sorry to hijack your thread .. but i juz wanna ask, my sand bed is only about 2 maybe 3 inches at the deepest point however i got little bubbles forming. i am using grade 0 sand (very fine) the bubbles are produced all over in the sand bed, i know this because i every stirr the sand before in the past. could it be nitrogen gas ? bubbles only appear ard 2 cm below the surface of the sand Quote Link to comment Share on other sites More sharing options...

SRC Member big_ben102000 Posted February 18, 2007 SRC Member Share Posted February 18, 2007 Do you have algae growing in your sandbed? sorry i think i miss read your reply. yes there are some aglae growing on the glass panels of which the bubbles form. however when i shifted the sand in the middle of the tank when i am rescaping my tank, bubbles will also float up to the surface.
