Hi Phil and Laurel, You might try Denny's Pet World in Kirkland, call first and ask for Seachem Flourish Excel. I was at A Place for Pets in Burien yesterday and they had one or two bottles on the shelf. Tom indicated further down on this thread that Midway had it for $8.99 for 8.5 ounces which is a good price at LFS (my LFS charged over $10 for the same size). With the high dosage I was using, I used up most of my 8.5 ounces bottle in the week of treatment for my 45 gallon tank. If I were to do it over, I might try the lower rate recommended by Luis and used by Erik and Larry and figure a two week treatment period. I am putting together an order for equipment for the 30 I am setting up and buying Excel 16.9 ounce at Thatfishplace.com for $8.49 since it will not affect my shipping cost for the other stuff I am ordering. I am still doing a maintenance treatment on my tank. No Hair Algae, BBA, or Staghorn Algae has reappeared in the last few days. I have not changed anything in my tank (fert dosing, light duration, water changes) and other than algae on the glass all other algae in my tank is gone. I am pleased with the results so far. Here are a couple of good links concerning Excel and its active ingredient, glutaraldehyde, if you are interested: http://www.aquaticplantcentral.com/forumapc/aquarium-algae-control-specific- problems/3806-flourish-excel-got-rid-all-my.html http://www.aquaticplantcentral.com/forumapc/south-western-ohio-aquatic-plant -enthusiasts/31615-glutaraldehyde-instead-excel.html Roy _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
