I do think it can be a quality discussion so long as it is kept polite. The other thread was not kept polite, hence the deleted post.

There are current studies that still show both sides of the debate. Studies from 2014-2015 still show issues with embryonic development and death in amphibians when exposed to uv. Studies from 2014-2015 also support uv. There is some suggestion that pesticides in the environment inhibit the amphibians to the point that they do not properly shelter themselves or their eggs from uv, but that is still at the level of hypothesis and suggestion rather than having provided proof last I read. There are a few that would make interesting reads, but they cost money. Because they are fairly new, I have not found other sites who have purchased, read, and reviewed the study for others to be able to access some of the information for free yet.

Either way, your frogs are thriving with UV, my frogs are thriving without UV and with calc +D3 supplements alone. Many people have the same experiences as both of us.
