Help Help Plants getting holes in leaves

[reef12]

Well not that bad ,but was wondering if anything I could do to cut down on the holes in plant leaves?
Seems a never ending problem here.
I use no fertilizer at all, all natural is the way I go.
Also the snail shells turn pure white and the snails die.
Is this a lack of calcium?

Pictures enclosed.

Tank has been up well over a year now.
No more Co2 run used to make bigger holes in the leaves.
A quarter water change every week.
Pictures taken during a water change , so reason of low water.

75 Gallon.

Thanks all

Is this a lack of calcium?
The shells turning white- yes. the death no telling.

So what should I put in for a calcium booster?

I guess might be the dang snails.

Thanks so far.:22:
