So, I know flourescent 6500K light bulbs are preferred, but I'm wondering if strong LED clip-on lamps are alright for planted tanks long-term. The ones I've got for my tanks have 60 very bright LED bulbs, though only about 70% of them are bright, the rest are blue, and I don't turn the blue ones on too often. (Should I be?)
I have only low-light plants (java fern, a few anubias varieties and a couple of crypt. wendtii, a little floating water sprite and soon to be some duckweed) and have so far seen no die-off whatsoever, however I have only slow growth. I did get a bit of that "crypt melt" thing people talk about with one of my plants, however it is not browning, or giving any other indication that it's not doing well, now that it's gone through an adjustment period.
Is this lighting setup going to be detrimental long-term, or will they be okay if I do not introduce any plants with higher lighting requirements? Is not seeing a lot of active growth an indication that my plants are suffering, or only that they're only getting enough light to survive, but not to explode with growth?
I'm cringing a little at the prospect of finding some clip-on lamps that can fit the bulbs more suited to plants, that will fit in the space I have for my tanks, so I hope that this LED setup will suffice, but thought I'd check because I don't really want to kill my plants after all the money I've spent on my tanks, hehe.
