I thought you said your plants were dying?
Yeah, no… and the more I look at the photos the more it becomes evident that they started to go south once I started “treating them” for aphids… I put them in direct morning sunlight for a couple of hours, then I submerged them for like a day, then I sprayed them with soap … now I’m laughing at how silly this sounds.
I thought the aphids were for sure killing my plants and I was saving them.
FeEDTA or FeDPTA won't hurt anything at the dosage I recommended. New leaves should turn green. EDTA is totally non-toxic and degraded within a week or so into miscellaneous, harmless organics.
This is still really good to know and I will be watchful of my future floating plants and keep it in mind…
You may have other deficiencies from too much water changing, tank cleaning, not enough fish food added, etc, but iron deficiency is the main nutrient deficiency for floating plants. Some floaters may be more adept at taking up iron.
You'll have to tinker with this.
I have definitely kept the water changes down to a minimum per your advice of letting nutrients build up… I did also realize I couldn’t overfeed with fishfood intentionally though, because the betta got bloated… like I might have to find another way?
Ah, yes. All those water changes to clear your green algae/ tannins would cause nutrient deficiencies.
I haven’t done as many water changes as you would think…….. I’ve been kind of living with my green water hoping the zooplankton I think I saw in there will help clear it up slowly...
I dunno. I keep trying to line this thread up with the other one on "siesta schedule - no lamp", and it seems the water didn't start to turn green until a month ago. That's not to say you're not on to something; the appearance of aphids on the floating plants clearly initiated a series of cascading events that could have coincided with gradual nutrient depletion in the glass bowl.
The important thing is that the floaters seem to be coming back - gradually.
Thank youuuuuu, yes. Yes. Thank you. I read so many times (in DWalstad’s book) that the floating plants are major in keeping algae away. As soon as I started treating the plants for aphids, outside of the bowl, I knew, that I would get algae. But I was so convinced that the aphids were going to kill my plants anyway that I didn’t think I had a choice.
I’m going to keep giving what’s left of my floaters (almost nothing) a chance to recover but also get new ones so the tank isn’t essentially without floaters much longer, and see how efficient/fast they’re able to help with the algae situation…I’m optimistic.
As for the aphids... I'll be watching the plants like a hawk and try picking them out by hand to try to keep them under control 🤷♀️ ...I don't really see another solution.
Sorry for the super long response and thank you SO MUCH. I’m learning so much and I’m super happy.
