Hi,
I had some thread/hair algae crop up. The algae is limited to large clumps of needle leaf java fern, not easily extracted by hand.
I mixed up a 50/50 Excel + water solution, then sprayed portions of the java fern most infested. It seemed to be effective with the algae, but also killed the java fern. They were nice huge clumps from GLA. Good clumps of anubia nana petite that took ages to develop were also knocked out.
What I did:
45ml of Excel + 45ml tank water
(volume of Excel to use derived from max water-change dose of Excel in my 90gal tank, which is 45ml)
During water removal at water change, I sprayed the java clumps once they were exposed as water drained.
I probably sprayed 80% of the solution I mixed.
Contact time was 30min before water filled tank again (completion of drain, followed by fill).
So... can you sage folk recommend what a good contact duration would be for a 50/50 Excel & water spray? Was my concentration too strong? (50/50 based on some of Tom's earlier indications)
(yes, I seek to address "root cause", but here ask about using the spray as a tool).
thanks,
