As a newcomer to the forum but not to fishkeeping, I wish to ask fellow members something I probably should know, but never really gave much thought before!
What is the effect on light falling upon the plants when passing through plastic or perspex, or even glass condensation trays? I am starting up a new tank with older type light starter units, the sort with just plastic cups to fit the tube pins into. I wish to use a perspex
condensation tray, both to minimise evaporation, and to reduce condensation upon the electrical connections, also as it is firmer to handle.
I've read somewhere about the effects of various rays of sunlight being prevented from passing through glass and the like, so am wondering if the tray would affect the lights quality, and therefore its affect on the plants may not be as effective as without a tray.
Can any members through any light on the subject (excuse the pun)
