Hi to all experts.
Two months ago I have started a brand new Denerle 60L nano cube for a CRS tank.
I used only new products in there.
The substrate was new Shirakura, with Benibachi Bee max and Benibachi Mineral powder.
The substrate system was set up according to Benibachi recommendations.
Additional products that I have used were;
Benibachi Black Control, Benibachi Nitrate Remover, Benibachi Amonia Remover all used only with the recommended amounts or a bit less than that. I never over dosed any of them.
I used also a small amount of filter bacteria from Easy Life to speed up the cycling time.
The water was only RO with Mosura GH booster.
Water parameters were;
GH – 5
KH – 0
Cond. – up to 200 uS
TDS – up to 150 ppm
This tank went anaerobic in just two months and the substrate smelled like shit hole.
Can anyone suggest what could possibly have gone wrong in there?
