when I mentioned the usual path of the red, its toking about the natural route which the red travels
if persay the red always swims near 2 inches from the water mark...assuming a red of 9" body width is around 4 inches...the total surface area need to cover is the (4"+2" =6" ) the best position for such a scnerio will be targetting somewhere near the 3 to 4" from water mark
**this is under the assumption of using PL tubes to tackle the tanning**
this way the light is around the eye level of the red and wun causes DE but still is able to catch on the tummy area of the red...helping it to tan it to show some base
