Did this after having trouble finding a tool/guy to bend a metal pipe for me.
Heres mine(cost about USD$7 and 1.5 hrs of my time):
I chose this "reflex bow" design so that it compensates the normal flexing that pvc experiences under load. Planning to refine the top portion, or even the entire stand when I have more time, rather crude now but needed to lift the light off the tank quite urgently. Also aim to hang my fan from the light eventually. Consider this V1...
15mm dia. 9' PVC pipe: $6
1mm dia. SS cables/clips: $3
Spray paint: Optional
Heat Gun: Borrowed from a friend
Sticky tape and drill are my own
You can do wonders with PVC and a heat gun!
Pardon the condition of the tank, trying to house some aggressive apistos, tending to severely malnourished celestial pearl danios, moving hiding spots and scaping all at the same time!
