staurogyne repens Melting or eaten

[Tom72]

Hi good folks of UKAPS,
Recently I posted a question about what might be eating my crypts, it was suggested that it was a nutrition issue, which I thought was unlikely until I discovered that my auto doser had malfunctioned, that is now fixed. The only major difference is that I stopped dosing Liquid CO2, but upped slightly the CO2 injection. Now this has spread to the carpet of staurogyne which is dying back fast, the frets are going in and I have added tropica root tabs. I have attached a before an after pic for comparison. And linked the other post. Crypts being munched
I look forward to your advice

@Tom72 , I am not sure about this at all, but at least for the crypts, that looks like melt to me... Crypts don't like changes. If your tanks been going strong for a long time and you had an "outrage" on your ferts dosing or changing your liquid CO2 dosing (why did you stop dosing liquid CO2 in the first place?), then thats probably why. Hopefully the Repens and Crypts will recover when everything stabilizes.

Cheers,
Michael
