could this work?
im very green on both fish and plants, so forgive any "silly" questions. lol age does not mean knowledge!
being from a photographic background, it occurs to me that the use of colour correction filters my offer some help in better growing conditions for plants, without the array of different tubes and bulbs normaly needed. i am aware that these filters will result in a loss of light, how much depends on the correction needed. i am aware that this will not be the "difinitive solution" just an alternitive, that may offer both useful light for plants, and also some amazing effects, with a very low outlay, a 36" square of correction filter costs £1.50, depending on the amount bought.
I have tried this only with a moonlight effect, true i have not looked into the correct colour temp needed for this, using a deep blue/purple filet simply layed on top of the tank and pointion a led white light at an angle to the filter, cloud effect was achived by buffing the upper surface of the filter with wire wool, in rounded patches. the effect is stunning, though how useful is another matter.
i would be glad of your input.
