Terryz_ Posted April 30, 2004 Share Posted April 30, 2004 If your sand bed is too deep, this will happen... The black patches/lines are Ammonia if i am not wrong.. Quote Member of: Link to comment Share on other sites More sharing options...
SRC Member Tanzy Posted April 30, 2004 SRC Member Share Posted April 30, 2004 Hydrogen sulphide, not ammonia. Quote Warning: Heavy handed moderator in operation.

SRC Member Tanzy Posted May 1, 2004 SRC Member Share Posted May 1, 2004 unknown, Don't worry. It's not a big problem as long as you don't disturb it.

SRC Member typrobin Posted May 1, 2004 SRC Member Share Posted May 1, 2004 wah....very dangerous leh....my DSB is 4-5inches deep and about 50% is black liao.... Quote MY OLD 3ft!! My Latest Plan!! Link to comment Share on other sites More sharing options...
Achilles Tang Posted May 1, 2004 Share Posted May 1, 2004 The black patches will come and go or expand or decrease in size. Just don't disturb it as its part of the denitrification process. The bubbles are also part of the nitrogen cycle... its the end result... nitrogen bubles. Congrats... your nitrates are being processed!

Achilles Tang Posted May 2, 2004 Share Posted May 2, 2004 Hm... but where should the bubbles be forming at the top or bottom of the DSB? It will form at the bottom where the anaerobic layer is and where the anaerobic bacteria will process nitrates as its food source and produce nitrogen bubbles that will slowly make its way upwards and out of the sandbed.
