I have Vals in sand, both PFS and Coral sand, and they are growing like crazy. Also in Safe-T-Sorb, and some other substrates (I do not remember which are in which tanks)
~No CO2 (note that vals can get carbon from carbonates)
~Temperature varies wildly, this is in a greenhouse and the plastic roof blew off last winter.
~Livestock is tadpoles and snails, and I am not feeding them.
~Ferts are water column, but irregularly added.
~Light is WAY higher than any indoor aquarium; Light meter shows about 30 in the shaded tanks, and into 3 digits in the tanks on the top shelf.
