I have noticed that my Jungle Vals are melting. I use the EI method and last week I ran out of Flourish but I have Seachem trace so I started using it , with the thought that once it was used up I could get back to the Flourish. I have also cut the amount of PO4 by half based on a Hagen test kit as it showed the tank levels to be higher than the kit could measure. Even now it still shows it to be high (5.0 mg/l). These two changes are the only things that have been changed, I do have CSM+B that I will add today. Any ideas on what is doing this? Any ideas that would solve this?
