I have 180 planted Discus tank. Plants went in about six weeks ago. I am using CO2, & fertilizer in substrate. I do a 50% WC every other day (for the Discus) & I add 1/4 teaspoon of potassium sulfate, ferrous gluconate, monopotassium phosphate, CSM+D, & 3/4 teaspoon of potassium nitrate to WC water ever time. This is less than EI but most of my plants are not fast growers & tank is not heavily planted so thought this would be good place to start.
For lighting, I have 4 48" T5's & 1 250wML 6K. They are pretty high above the tank & i put some window screen under the center of the ML because it was much brighter in the middle of the tank than the ends. T5's on for 9 hrs, ML on for 4 hrs, par reading with T5's only about 25 in middle & 17-18 on ends, par reading with T5's & ML 50 middle & 40 on ends.
Water stays ph 6.6 to 6.8, KH 3, GH 4, temp 83
I have some algae & would like to know you think I need to do to stop it. less light, less time, more fertilizer?
FTS today. the monster plant on the left was a bulb with NO leafs six weeks ago, grew to the top & current has turned it back on its self 8-10" more. My plan is to keep the middle open for swimming room for the Discus. There is three dwarf water lilies in the center I plan to let grow to the surface to shade the center some.
This is the worst of the algae on the crinums.
Some green algae on rocks.
Not sure if this is algae or if the java fern is putting out roots???
I had a planted tank years ago, ran great. No CO2 no fertilizer & only hardware store full spectrum T12's or something like it. Plants grew slow but all was well when I got the light level right. Thought I'd try the high tech style this time. http://forum.simplydiscus.com/showth...ed-Discus-tank
Here's a link to my build thread on Simply Discus if you'd like to see it. Lot more detail on lighting & filtration.
If you need any more info I'm ready. What do think???
