DIY T5 Fixture
Wondering about how feasible it would be to use the electrical components of a fishneedit T5HO fixture to serve as the basis for a DIY hood?
I have a 75 gallon tank with the 2 tube T5HO which I don’t feel is bright enough. Recently I replaced the bulbs with Giessman daylight bulbs, thinking perhaps that would help, but I did not notice a discernible difference. In searching around, I found at least one reference to the fishneedit fixture having bulbs too close and a potentially inadequate reflector. There are also a number of recommendations for Tek T5 reflectors.
Before upgrading to the 75, I had a 29 gal planted tank with a pair of AH Supply 55watt CF lights which to my eyes was much brighter, and the plants grew better. I could obviously purchase a pair of their 54watt kits and do something with the fishneedit fixture, but then I thought it might be cheaper for me to buy a pair of the Tek reflectors, and use the electrical components from the fishneedit fixture in a DIY fixture.
I’ve built several fixtures in the past for AH supply things, and in this case I can build one for this tank. Given the tank is 18” wide, how far apart should I plan to house the bulbs?
