Live Tank, Still Cycling, Algae, Fertalize?

Cdbaby123

Hi! I started my first planted tank 2 weeks ago. My plants have grown, my cycle is moving along. I have a Fluval 3.0 plant light set on Auto with 2.5 hours sunrise, 7 hours daylight 2.5 hours sunset and 2 hours moonlight. I do not have Co2.
My water parameters are:
API Master Test Kit
PH 7.6
Ammonia 0
Nitrites 5+
Nitrates 30ish
KH 4 drops
GH 6 drops

I have algae growing; which I know is good. My question is; should I fertilize the plants? I used some root tabs when I planted then as well at Aquarium Co-op east green in the water when I planted everything, and then a week later I put one squirt of the fertilizer in the water. With the algae should I wait to put more or should I put in another squirt???? Attached are some pictures one from the day I planted and the other from today.
Thoughts?
Thank you for your help.

Algae is common for newly set up planted tanks, however I would decrease your light cycle to 8 hours max for the total time the lights are on otherwise your algae will outcompete your plants. As for ferts, I would start at half dose per the bottle instructions, especially because your nitrates are high from the cycle. Fertilizers will add nitrate to the water column so always pay attention to dosage once you have fish in, you can easily overdose the nitrates by accident and either cause an algae bloom or fish stress. I usually ease into the ferts until the plants are more grown in, less plant mass=less need for nutrients. Providing more nutrients than your plants currently need will also produce algae issues.

I don’t add ferts until the plants ask for it.

I also use Fluval 3.0. The sunrise and sunset is for the fish (or aesthetics) not the plants. They just need a short while to adjust. I’d change the 2.5 hours to 15 minutes and the 7 hours to 5 and with that tank - it’s not filled out or fully planted the power on the light shouldn’t be more than 50%, more like 40%. The lighting is what’s causing the hair algae on your moss.

Once the plants start filling out or, would I’d recommend is plant even more, you can slowly increase light and ferts but that tank does not need a lot of either at this point. That algae is going to cover and kill everything.
