I am pretty frustrated by my tank progress, and I'm really not sure what I am doing wrong.
Here are the basics:
- 55gal tank, started 3 months ago or so
- Turface substrate
- Nova Extreme 108W T5HO light fixture, on for 6 hours a day (started at 8 but had too much algae)
- EI dosing 3 times a week of 1/2tsp KNO3, 1/8tsp KH2PO4, 1/8tsp K2SO4, 1/8tsp CSM+B
- CO2 injection to the point of just below fish being stressed out. None of my plants is pearling, but I do get some continuous streams of O2 bubbles from some damaged leaves, so I know the CO2 is "working." CO2 is injected via a Sergey's (Cerges) reactor
- Eheim 2213 is the filter I am using (I am using a 2217 on my other 55gal, which is quite more powerful but the flow gets reduced by a Rex Grigg reactor there)
- I have a Hagen Elite Mini that sits a couple inches under the water surface to create some ripples on the surface and provide additional water movement
- For fish, I have:
2 juvenile angels, 6 black neon tetras (I think they are nibbling on some of my plants), 6 longfin danios, 3 harlequin rasboras, 2 bolivian rams, and a clown pleco
- For plants, I need help identifying the other ones but the ones I remember names for are:
- e.tenellus (grows well, with blades wide and long)
- ruffle swords (doing just ok, not great, but then there's not much in the substrate for the roots to feed on yet)
- wisteria (growing ok, but leaves have little specs of algae on them)
- crypt balansae - don't know if it's growing or not
- creeping charlie - curled leaves, algae grows on them
- corkscrew val - grows slowly - again, algae
- rotala sp. green - when i bought a ton of it from a member on this forum, it was all uniformly beautiful, vibrant green with large healthy blades. New growth coming in is much smaller, and the existing leaves get covered in small specs of algae or perhaps are just dying off, not sure.
- some different hygrophila's - not doing fantastic - as you can see in the pictures, older leaves are large and long and dark, new leaves are coming in "crippled"
- giant hairgrass - not growing, not dying, covered with algae
I am really not sure what my problems might be. I do regular water changes, I have a lot of light, I add fertilizers regularly, I inject CO2 and have evidence that the water gets saturated. So, how come I am not getting a lush green tank? I am not a novice and I've spent countless hours reading about this over the last few years. In another 55 gallon tank I have, a melon sword I have is growing out of control. Its new leaves are beautiful melon red and are 4 inches wide and 18" tall, just insane! But, this one is off to a rocky start. Or... ?
