I have a 54 corner tank, and I am having a lot or trouble with cyanobacteria. Water quality is great, but I think I have too little flow. [FONT=verdana, geneva, lucida, lucida grande, arial, helvetica, sans-serif]I currently have a hydor 400gph on the side, a maxi jet 900 in the back, and the return pump is 250gph from the filter. I also have a 55 gallon tank that I have never had any problems with. I am curious as to what set up any other hobbyists with a bowfront are using. [/FONT]
