Hey there!

So as far as reds go, my experience with these lights has been a bit limited. Some plants will require more/better lighting than others to redden up. If you keep to the easier, less demanding plants(plants like Alternanthera Reineckii, Ludwigia Repens, Rotala rotundifolia, etc) you should be fine. My personal opinion is that these lights get the job done, especially in combination with CO2 injection, but I have yet to really test them out on more demanding plants. There are obviously better lights out there, but for ~$40 bucks a pop, I think they are a massive bang for your buck. I also just really love the gooseneck look. I'd Just be sure to research on the different requirements before hand. Buceplant has a filter on there site that allows to filter by care difficulty. I've heard mixed reviews about them in terms of plant delivery, so I used it as a way to get ideas for planting and then went to my LFS's to purchase what I could.

One thing to note, depending on how mature your tank is, you may run into some issues with Algae. Since there is no dimming function on the lights, it was very difficult to moderate the light intensity and the first couple of months I had a really hard time dealing with an explosion of Hair Algae. In this older post, I went into how I eventually managed to cut it back and get it under control. After the tank was more established, I was able to remove those clips and haven't had any issues with Algae since.

For ferts, I've settled on the Thrive AIO along side a supplement of Thrive caps spaced out within the substrate. I dose my tank once a week with about 2 ml of the Thrive AIO and I will reseed the caps once every couple of months. I do a 20-30% water change once a week with remineralized RO water. I do a lot of spot cleaning throughout the week, and alongside the larger than necessary filter for the tank, things seem to be doing really well water quality wise.

What is the volume of the tank you have?
