A nano tank layout featuring holy cave, 23 L (6.1 gal.), Aquatic Garden style, by vasconcelos. The composition is built around seryouh stone.
Read the stone and wood (seryouh stone) as visual pathways before judging the plant mass. About 9 plant species are listed — fine for a multi-layer look, but keep a care log so slower species are not shaded out. ocean tech plant grow substrate helps stabilize root-zone nutrition in the early weeks.
serie a chihiros lighting sits at a moderate-to-high technical level for this nano tank. eheim filtration needs enough turnovers without blasting the hardscape; browse matching filters. On nano tanks, ramp light intensity over the first 2–3 weeks to limit hair algae.
