I have the Seneye reef . Love It ! you just have to buy the slides which Reef rediance sells .3 months 30 dollars. I like the Par meter that Is well worth It . So far It helped me place my corals and all Is doing well so far . It moniters PH ,Nh4,temp . I have it connected to my laptop which is right next to my Tank . I do use the Par meter on all my other tanks when placing corals .
