OK thanks, going to start with a blackout then drop the lightning down to 5 hours and see if that helps.

It will help but better to get to the root of the issue.

Tank details would help along with filters and media in filters
Light details
CO2 being used
Fert regime
WC frequency, % and maintenance
clean up crew
other tank inmates and feeding frequency

Unfortunately no liquid carbon available.

Its a juwel lido 120 (depth 55cm)
Built in filter and media (4x sponges 1x bio)
2x T5 24w (no reflectors) 8hrs daily
Low tech (no co2)
EI dosing, 10ml macro, 10ml trace per week
50% weekly water change the last 4 week, prior to that hit and miss!
Cleaner shrimp and ottos
Feeding every few days

Hopefully that helps? Thanks

Not the best image but gives you an idea of tank. Lots of floaters also which aren't visible.

Some looks really healthy whilst others have holes and melting. these melting leaves release Dissolved Organic Compounds ( DOC) and there will also be a detritus produced as the leaves melt. Both the DOC and detritus have been claimed to contribute to BBA thriving in tanks. All the dead/dying leaves need removing.

Missed you post with tank specs :oops:

when was the last time you cleaned your filters sponges? and vacuumed the substrate ? Plus what is the substrate? Gravel?

Do you dose Macros and Micro on different days of week?

Just a quick comment, as I believe other members can aid you better on this issue.
I couldn't help noticing the intake on your filter looks to be full of plants. Is the flow still decent and filter clean?

I'll try and get rid of all the melted leaves.
Filters and sponges cleaned with the weekly water change along with vacuuming the gravel. Substrate is ada amazonia topped with gravel, it is very old now though. Prob 8 years ish!
Flow still seems good and power head cleaned also. I'm in the process of making a ring for the floater so should sort then blocking the inlet too.

Macros and micros dosed on different days yes. :thumbup:

Hi all,
got a pic off them from above so we can see colour of leaves
Sure have, heres one under each of the tubes (they're different types hence the colour difference)
Lots of floaters also which aren't visible.
Perfect. The holes in the older Salvinia leaves ("snake bite lesions") are a deficiency symptom. It might be <"iron (Fe) deficiency">, which the plants have now grown out of, or it might be low magnesium (Mg).

I don't know which element it is, but when I started adding a small amount of iron and magnesium, <"on a regular basis">, it went away.

cheers Darrel
