I set up a new (to me) 72gal (48" bow front) tank about 2 months ago, and I'm having trouble getting plants to carpet.
I used filtration media and water from a clean established tank and was able to cycle pretty fast. I left the tank with no plants for about 3 weeks, and then installed the Co2 and a bunch of Stigma and some reineckii mini both from Tropica.
Also, I have been fertilizing with Seachem comprehensive 2-3 times per week, Seachem nitrogen, potassium, and Phosphorous, and doing a 20-30% water change weekly.
My Stigma is not shooting runners and it seems to be thinning out and getting pale. The Reineckii is darkening and losing its red hue.
I have some powder ferts on-hand and I could switch to doing EI, but I think what I'm doing already should be good enough to get the plants to at least not die. What am I missing?
There was a green algae bloom before I planted, presumably because I had the light on and the substrate was full of nutrients with no plants. Once I planted and added Co2, the algae is a lot milder.
- 20gal sump with plenty of bioballs and ceramic media from an established tank, purigen, act. charcoal
- Sump pump is capable of ~ 750 gal per hour
- UV sterilizer (currently in the tank, planning on moving to the pump compartment of sump)
- 72W MicMol LED AA-900 Planted lamp on auto settings (gradual on-off cycle about 9h/day)
- Co2 - My bubble counter is broken, so I eyeballed the pressure to keep drop checker green. Using 4dKH.
- Flourite + Aquasoil substrate. ~2-3in deep
- Rock hardscape
- 25-26℃ (77-79F)
- 0 Nitrite
- 0 Amonia
- ~ 40 mg/L Nitrate
- 6.0 pH
Some pics of the plants below. I will post better pics once I clean the algae off the back glass.
Thanks in advance, all!
