Browner Posted May 7, 2021 Share Posted May 7, 2021 Hi All. Here's the situation: Simple 15G tank setup (Fluval Flex), 4 platys + 2 more fry that we managed to save in a breeding tank that are doing well. My main concern: My plants don't seem to be thriving, and I'm afraid the newly appearing algae is possibly out-competing them. Tank is about 2 months old. Nitrogen cycle seems well established (near-zero ammonia, low-to-zero nitrites, and nitrates range from low to up to 30/40 ppm, depending on fertilizer dosing. I currently have some moss, which is doing fine. 2nd plant that's "probably" something like hygrophila polysperma, although I honestly don't know. This one is interesting - the bottom leaves look pretty bad, covered in black/brown spots and some holes, look like they're dying away, but the top is looking great, new leaves growing in emerald green. I also pruned and replanted a couple stems from this, and the new plants look to be doing ok thusfar. Last plant - star grass. It was growing like crazy at the start, but now seems to be slowing down and looks......... unhealthy. This seems to have coincided with a lot of algae (pretty sure it's diatoms - brown gunk covering the walls and the gravel). I just recently started fertilizing a week ago (that "one step" or whatever it's called from Aquarium co-op). Interestingly that's when the star grass seemed to have taken a bit of a dive. Gravel on the bottom is quite coarse, because 5-year old girls like florescent fun stuff, not proper substrate. Any suggestions? Should I try to clean all the algae off surfaces during weekly water changes? Should I continue to fertilize or is that making it worse? I was hoping the star grass would eventually achieve a carpet-effect through pruning and propagation, but now I'm worried they aren't going to make it! Lights are on about 10-12 hours a day - too much? Any tips much appreciated (fish are doing fine - it's just the plants that are a concern). Thanks!!!
