I’ve had been considering a small dyi led project at add a bit more coral pop and slight added par by adding a couple hyper violet and royal blue led chips but now I have seen black light led bars on Amazon and have started thinking this may be the way to go , way easier, that said the black light bars I see claim 395nm which is a bit lower then the 415 nm hyper violet I was going with but..... harmful? my research says debatable , has anyone used black lights in their tanks for this effect and if so can you share the good and bad and ugly if any of this - thanks
