I've had my tank for a few months now and am getting frustrated with my plants. They are not dying, but don't look healthy are are not growing.
TANK: 20gal 24Lx13wx17h
LIGHT:18" 15watt full spectrum
SUBSTRATE: 1/2 eco complete substrate. 1/2 quarter inch stones
FERTILIZER: Flourish Seachem. Weekly doses
TEMP: always right around 79 degrees
PH: around 7, but just ordered an API Pro kit to replace test strips
All other tests seem to be in normal ranges....according to test strips
FISH: 7 fish, 3 red cherry shrimp. just lost my Oto Cat
PLANTS: 2crypt parva, 1rangeri sword, 2bronze wendtii, 1lutea, 3noname grasses
My main question is why my plants arent growing. lights are on a 9hr cycle, I use weekly flourish seachem doses, weekly 25%-40% water changes always with conditioner....is it the lights? I just ordered a Co2 diffuser to go with my DIY Co2 system which will be in in a few days.
If you tell me to get better lights please give me some recommendations and/or links....I've been reading and shopping for the past couple nights and am really not sure which way to go. Theres so many options and brands and I don't want to buy the wrong one. Aqueon doesnt make a good versatile hood, so I'm ready to make a decent investment.
ANY advice will be MUCH appreciated!!!
