holes in dwarf lily leaves

[BlackCrappieLover]

Hello everyone!

My dwarf aquarium lily has recently developed holes in its leaves, primarily the lily pads it's sent up, but also some on the submerged leaves too.

My tank is 20 gallons and my parameters are as follows: 0ppm ammonia, 0ppm nitrites, 5-10ppm nitrates, 75ppm gh, 80ppm kh, and ph is ~7. I dose 10ml leaf zone (5ml tuesdays+thursdays). 1ml flourish (sundays after water change), and there are ~3 broken up api root tabs underneath the lily itself (put there 2 weeks ago). I also use a hygger light that I leave on for 8hrs a day.

I'm trying to figure out if I have a nutrient/lighting issue, because I'm noticing stunted growth from my dwarf sag and swords as well. There are ramshorns in this tank so I'm not sure if they're not just munching on the leaves 😅

My first guess would be a potassium deficiency possibly. Especially if it’s not on new leaves and happening on old ones

How many Ramshorn do you have? I have the same issue with Amazon Swords in my Kitty Tank but I think its the snails munching as their population has exploded in that tank to the point I have added Assassin Snails. 🙃

I'm wondering that now as well, especially after looking around at my other plants and my java ferns are starting to show some holes with black edges. 🤔

The population goes up and down. Right now it's very low, maybe around 50 snails in the tank because I've reduced feeding and am cleaning the sand regularly (as well as removing snails to put in my snail only 3gal). The population was at a point where you flick the lights on in the morning and the tank walls were just snail, snail, snails everywhere on the glass! It was crazy for awhile 😅. I haven't actually seen the snails munching on anything other than mulm or food the corys miss, I just threw that out there in case it's a possibility.
