I can't find the balance between healthy plant growth and algae and it is driving me crazy.

Hello everyone,

I have recently set up a new planted tank. I have been out of the hobby for several years but recently got the itch. I previously had a tank set up but had lots of algae issues and eventually gave up out of frustration. I feel like I am close to that again which is very discouraging.

This time, I have a Fluval Spec V set up. I will list some more details below:

Tank: Fluval Spec V (all-in-one 5 gallon set up with built in filter compartment)
Light: Current USA Satellite Plus Pro
CO2: Pressurized (approx 1.5 pH drop, probably too much as my betta gets lethargic during CO2 hours)
Stock: Betta
Substrate: Aquasoil
Weekly maintenance: 50% WC, rinse filter media

Fertilizer: DIY solution (ppm per week below)
N: 15 P: 2 K: 20 Fe: 0.5 (as CSM-B)

One of the benefits of the Current USA Satellite Plus Pro is its adjustability, however I just can't seem to find the balance with this thing. Either my plants are growing slowly and sparsely, or they become covered with hair/fuzz/thread type algae. I don't have any livestock that eats algae in the tank (amanos, etc), but I feel like I should be able to find this balance without having to rely on algae eating organisms.

I need help. I'm begging for help. I don't really know what to do next. I have tried changing light intensity but as I stated earlier, can't find that balance. I think I need to be more patient and not keep changing things so much, but I don't know where to start. I feel that when I start my lights too low, the plants grow poorly making them weak, then when I ramp my light up, the plants are vulnerable and the algae attacks.

I'm wondering if anyone has used this specific light on this specific tank perhaps? Would be really helpful to know what % you have the light on if so. Please help me! Thank you!
