stained tubing..

[Subsider]

Tygon 2075. Minimum order costs $43.10 for 10 feet. I guess I am headed that direction, but I really don't like that 1/8" thin wall, compared to my usual 1/4" thick wall.

What tubing where you usein that had 1/4 wall ? tygon 3603 is 1/8 wall

o and UV sterilizer bulbs do kill Algae as well as bacteria ! plant life needs the visable light spectrum mainly the reds - violet or 1700K-10000Kelvin ! im not sure where we would cat. the UV leds/tubes we use being that there just within the visable spectrum or the blue , green or even red leds/tubes as there not full or wide spectrum (sun light at high noon is about 5200 Kelvin and ideal for plant growth , alge growth although a plant need less) but i dont think they would be a big concern compared to say sun light from a nearby window or the light from a RGB monitor thats about 6500K that would .
