So I have been having problems with my parameters. My supplier says everything looks good. My tank looks like crap and I am battling red hair algae for the third time and turning the lights off does no good. I have lost a 14 head hammer and several fish. He states it's because I don't have enough live rock, so i'm trying to build my rock up (currently at 120lbs). My tank is a 180 gallon tall, I have a eshopps wet/dry rated up to 300 gallon. People on here stated it is most likely a magnesium problem so I ordered a salifert kit. My magnesium level was unreadable. The water never changed colors. My other parameters today are Ca 400; Kh 12; Phos 0.25; nitrate 20; high range PH 8.4; amonia 0; nitrite 0, salinity 1.025. HELP, I am not trusting my supplier. He brought out the antique looking marine book and showed me parameters that were no where near those posted on here.
