Looking for some advice...I currently have a standard 220 and have run AI Sols for the last 10 years...I've never really cared for the spectrum and haven't been happy with the LEDs anyway. I've needed to upgrade the lights, but never wanted to spend the money to do so. I saw a video that Tidal Gardens put out on HO T5 fixtures purchased on Amazon. I have been trying to justify spending the money on a ATI or Giesemann fixture, but can't bring myself to do it. I keep a softie/anemone dominated tank and am happy with the ease of the ecosystem I have created. My last lighting purchase(before AI Sols) was a retrofit T5 unit that I want to recreate. I'm probably going to purchase a few of the units on Amazon and buy ATI bulbs(due to color spectrum). My question is...Amazon only has 4 ft and 2 ft fixtures...do I purchase 3X2ft fixtures or buy 1X4ft and 1X2ft fixture? Will it make any difference? If I buy 3X2ft fixtures, I need to by 4 more bulbs...just looking for some advice and thoughts on this...Thanks in advance for response.
