Lessee... 15 gallon "tall", Aquaclear 30 HOB filter, one bag of Eco-complete, modified strip light with 15 watt T6 bulb and homemade mylar reflector on for 12 hours daily.
The tank gets 2.5 ml Excel daily, and 1/32 tsp KNO3, KH2PO4, K2SO4, and CSM+B every week or two. Water changes only when I need to do maintenance, every few months.
1 Male Betta
1 Corydoras pygmaeus, down from 6
1 Parotocinclus sp.
Ramshorn snails, aka betta snacks
Cryptocoryne wendtii, willisii 'lucens', beckettii 'petchii'
Java fern "windelov"
Anubias nana, and nana "petite"
Red root floater
The lighting is so low, I don't think the Excel actually does anything, but I'm too scared to stop using it
The plants grow at an extreme snails pace, and the stems will stop growing and die if shaded. When this tank is redone this winter, I will definitely add more light to make the tank more manageable to 'scape.
