I have a 140 gal freshwater discus tank with a 30 gal refugium. i have 2 6700 36in bulbs and 2 150watt halos, i dont run the halos really anymore. lights run 8hrs and i have co2 putting in about 4bps, i use the greenleaf pro daily ferts. i have some amazon swords, Dwarf Sagittaria and sagittaria. i am having no luck in getting them to grow well. they all look bad and not really growing. have brown leaves and some holes in them. and i have the eco complete substrate.

i really want this tank to become full of plants any help would be awesome.

thanks

How old is the tank? (How long since you first set it up and started it's cycle) Also, please post your water parameters as well as how long you keep lights on..

1 more thing... why the refugium? What plants are in it? I would think the refuge would be much more useful if converted into a biomedia filter..

It's been running for 6 months, and I will get the water parameters when I get home tonight. I keep the 2 67k 36in lights on for 8hrs. Anacharis is what I have in the refug.. I was told to do it this way. Have no experience with a sump/refugium. If there's a better more efficient way to do it, I would b willing to change it.

How deep is the tank in inches? I'm thinking that those bulbs aren't penetrating very well.. Also, what brand are these bulbs? I'd consider turning on the halos in the middle of the 8 hours for about 2-3 hours and see if things improve.

Definitely keep those nitrates down to 5-10 for now.. your tank won't need the 15-20 nitrate range until it's more heavily planted.

What filter do you have running besides the refugium? Also, I'd look into putting some micranthemum umbrosum or even a hygrophilia into the refugium too.. I can't say how well they would do but those are the two hardiest/fastest growing plants I have experience with..

Try looking into dosing different ferts too.. like flourish comprehensive supplement or a powder macro fert.


Also keep in mind that bulbs do go bad after so long.. typically a year or so.. depending on usage.
