I have had a reef tank set up for the past 32 years and I am SO SICK of the Neptune Apex System. The %$&#@!!! thing NEVER works correctly. There is always something messed up or off-line or screwed up. Their support is only open M-F from 9-5 when all the people that have a real job and can afford a reef tank are at work and cant call for help. I think they planned that on purpose. One of my NEW Wave pumps quit working and they would not replace it so I bought a new one and for the last 3 months it wont work because is says MISSING on the Apex controller. The specific gravity prob is garbage, Half the time the control outlets don't work. Then you always have to put in some $#%@ pass code.........Why do I need a pass code? The Russians going to sneak my settings?. This whole piece of crap is going in the garbage, pumps and all. I want control back.
