light siesta mainly regarding plant health and staghorn algae
I have a relatively young dirted, planted tank of about 20-22 gallons (its a 32 cube not quite full and with a fair bit of soil/gravel and wood/hardscape to displace). Its about 2 months old is all. Soil under gravel is eB stones premier/420 blend.. fairly rich but of course designed for veggies etc not aquariums.
Dont have parameters as my lfs has been testing, but nitrogen was essentially zero after cycling, and we have pretty hard water here.
I have a lot of floating duckweed, some Anubias, java moss, Rotala, Ludwigia. Probably need more plants. It has a fluval 207, and since about 10 days only, aeration w bubbles. The plants, other than the duckweed, could probably be growing faster. Anubias older leaves getting staghorn, esp on the edges, and newest leaves are somewhat crumpled downward on the margins... Rotala new growth somewhat yellow.
staghorn has been kinda blowing up over the past month, on one piece of wood closest to the light. I was going about 10 hours of light plus the sunrise/sunset, and fairly low on pink.
Now I have in pro-mode, with about 4 bright hours, followed by a 4 hour siesta, then four more bright, with the reds high on both well lit periods..
My darker period in the middle is not *dark* but everything is at or less than 10%. Would this help disadvantage algae?
Everything Ive read about staghorn algae indicates it comes on with low C02 or night ammonia.. I need to test but ammonia has never been detected...
