How long is laterite capable of holiding onto the active ingredients in medications?
I treated my tank with Clout about 2 years ago, ran carbon for about a month to get rid of whatever may have persisted through the water changes. However, I am still having problems with keeping shrimp, and I am almost thinking that the laterite could still be holding something.
Is this possible?
I am also dosing Flourish, Flourish Iron, Potassium, and Phosphate, as well as Excell.
It also seems that my attemps at keeping shrimp are becoming increasingly successful, I see one almost every day now, and its been there about 2 months. I believe this is the longest I had one last so far.
Could it be that water changes are diluting out whatever the laterite is holding, or is it something else?
Sorry about the length.
Thanks in advance.
