Hi All, A friend of mine was offered a 55gal tank and asked me about a good beginner's book. I've been keeping fish for the last 20 years but only 6 in the US so I do not know of a good book to advise to him. Any suggestions? My 2nd question concerns cyanobacteria. I have some growing in two 75 gal tanks. I let my tanks unattended while I was gone for 10 days and that is how they appeared. I am not for using products but despite weekly removal and bi-weekly water changes they are still in. I am careful about feeding, plant detritus monitoring... and therefore there is low OM in the tank. Erythromycin is supposed to do the job. Would someone know where I could get some (that is more than 10 tablets like what you find in stores) at a reasonable price? Also, are there other products that can be used (kanamycin, other.?). Thanks all, Have a great week Yvan Alleau Work Home Oregon State University 450 SE Atwood Avenue College of Oceanic and Atmospheric Sciences/ Corvallis, OR 97333 Hatfield Marine Science Center 541-231-9544 2030 SE Marine Science Drive http://southamericancichlids.com/ Newport, OR 97365 1-541-867-0206 ----------------------------------------------------------------------- -- This is the apistogramma mailing list, apisto@listbox.com.
