I have a densely planted 55 gal with pressurized CO2. I have a dual bulb Glo HO t5 running for ~9 hrs a day. It's been running for about a month and a half and my plants are growing incredibly! This past week, I recently ran into some GSA on my anubias and red hygro. I want to dose phosphates to try to combat this but was told on a different thread to try the PPS-Pro method. I purchased them from Green Leaf but I'm wondering if adding all those nutrients will throw off the balance I already have, creating more algae issues. I'm new to fertilizer dosing, and I've read tons of PPS-Pro threads. I'm just afraid of drastically altering my water chemistry.

Any help would be AWESOME,
Michael

what is your substrate?

what is your substrate?
I'm no expert but from what I've read, Co2+high light and no ferts will lead to some major algae issues. If you are using nutrient rich substrate things might be different. Other members with dirted tanks can probably provide better advice.

If anything, not dosing fertilizers will bring you further out of balance. Your plants are growing very well due to the amount of light you have along with the injection of CO2. However, they also are using up nutrients at an incredible rate. Without nutrients, plants will start become less healthy, allowing algae to gain a foothold.

By dosing, you will allow the plants to continue growing well, and the algae should subside.

On another note, your photoperiod seems a bit long; I would try reducing it down to 7-8 hours as well.
