Here is my initial hardscape for my nano dennerle tank. I’ve spent ages balancing the rocks, gluing them where necessary and filling in all the gaps to stop the soil getting through to the sand. Have temporarily filled it with water to see if any sloping soil rolls down/filters through gaps . Success! Will drain it down again for planting. Dennerle cube 30 litre JBL co2 with solenoid and diffuser Using and Old Eheim classic filter with glassware Chihiros lighting JBL soil JBL Sansibar River sand Dragon stone (lots of pieces!) Would like some suggestions for plant species. Definitely want to use HC Cuba. Lots of pockets of soil to fill between stones for other species too. Also, Maybe something interesting for the open bed to the right edge of the tank?
