Holes in leaves

[Mattant1984]

Hi all,

So some of my plants have started to show holes in some of the leaves and its only been the last 2 weeks that it's been happening. Its even started happening on my tiger lotus.

Been reading a few posts on here and wondered if it could be a potassium or iron issue??

-120l tank
-No CO2
-8 hours of light per day on timer
-50% water change weekly
-Solufeed 2:1:4 three times a week at 1g
-Tropica aquasoil
-PH about 6.8
-KH 3
-GH 7
-Temp 24


Thanks

Could you list all the fish, shrimp and snail species in the tank?
Some of these look suspiciously like mechanical damage

I currently have 10 corries, 5 cardinals, 15 ember tetras, 5 amano shrimp.and a load of cherry shrimp

Do the amanos get fed well? They are known to turn on plants if dissatisfied with the menu

I’ve seen this happen with fish picking baby snails off leaves too.

Errrr I would say that eat a fair amount of the fish food I put in however I do feed fairly lightly to the fish. Maybe I should supplement the amanos more

A full tank shot would be helpful, also what lighting do you have?

@John q please see full tank shot and lighting is 2 nicrew led lights. One is full spectrum and the other just blue and white

Tank looks bob on mate 👍

I just wonder with the amount of light you have in there if there's sufficient flow reaching some of the areas. Some of the bottom leaves on the hygrophila and ludwigia look to be disintegrating, this would suggest the light is maybe a tad bright for the amount of co2 that's supplied in these areas, it could also explain the pin holes, assuming it's not mechanical damage.

I can also see a milky film on half of the surface of the water. Is there anyway surface agitation could be improved, would doing this increase the flow to the areas that these issues are appearing?

Just thinking out loud matt.

Thanks for your comments @John q I would agree some of the bottom leaves on some of the stems are not doing great.

I thought I had fairly good flow as I'm running an Oase biomaster 600 Which is pretty big for the tank size however I wonder if changing the outlet of the filter to a spray bar would help with flow and also the surface film 🤔🤔 worth a go I supose.

Would you suggest to reduce the lighting intensity a little??

Lol, I always suggest that 😀

Have a play with the flow direction you have with the current outlets, and see if it can improve the surface ripple/flow around the tank. Definitely want to get rid of that surface film. If that doesn't help, dimming the lights a tad won't do any harm.

I will give that a go mate thanks again for your help.
I will also try feeding the shrimp a little more I think just incase it is mechanical damage.
