How is the Excell on the Staghorn? That might be my problem area. I've been giving the tank initial dose for two days. How much longer?
If you do the initial dose twice you'll kill most of your fish/invertebrates.When people say double, triple dose is that?
*Double the initial 5ml for every 10 gallons, or
*Double the daily dose: 1 capful for every 50 gallons
Scratch that...Algae trumpted the Excel...Algae came back. Temporary success was about all I acheived..but it always came back.Amen! I read this thread (after nearly giving up on the algae problem (really bad)). I started dosing with Excel and the algae is GONE. Amazing stuff. I have lost no fish and seen no adverse affects of any of the fish in my tank. This should go to the top of the list of things to try before one engages in the multi-variable, complex technical discussion about all the things that might influence algae such as lights, nutrients, etc.
