I have a 2.5 gallon unfiltered tank that I have two plants in. The plants were thriving until 2 weeks ago when I did a 100 water change. I took everything out of the tank, rinced it off and put it back in with the same water conditioner that I always use. Ever since then the leaves have been turning brown and falling off. I have tried plant fertilizers and an LED grow light but they haven't gotten better. Anyone know what happened and how to fix it? I miss my lush tank.
You may had changed the water chemistry too much to the point they will need to adjust to the water again (Just guessing). When I perform water changes I only change 50% and once a week add fertilizer and CO2.
I also do not touch the substrate during water changes so I do not ruin the roots of the plants.
The bowl has one betta and is gravel only. I have had the bowl for several months only doing partial water changes twice a week. I use a gravel vacuum but was noticing lately that even with the vac when I added the fresh water it back in it was still stirring up a lot of particles and that led me to do the 100% change. I took everything out of the tank, gravel included and just rinsed everything off. Not a major scrub, just a rinse and then reassembled everything back in. That's when I noticed the plants starting to lose leaves. I started with Leaf Zone and a red/ blue led grow lite for plants with no change. I'm hoping they come back at some point. Can I add more Leaf Zone then recommended without hurting the fish?
I'm not sure either what type of plants they are, I got them at petco and they were just labeled as medium sized, no botanical name that I could see, I didn't really care at the time to know what type they were :)
