I'm very confused by the T5 lights. I need to order new lights for the 75G and I'm not sure what / how many to order.( right now I have a spare 192w PC fixture on it) I believe the 48" fixture has 2- 54w T5's in it. Do I need a 2-54w lamp fixture or a 4-54w lamp fixture? Should I do the standard 1/2 10000k and 1/2 actinic or should I mix them differently if I go with the 4 lamp fixture?
The depth from the top of the tank to the top of the sandbed is only 18-19".
This is my new Seahorse tank so there won't be any coral in here, just macros and sea grasses. The macros do not require intense light, but some of the sea grasses need more light. Even if I decide later to add some corals, they will all softies like zoanthids and leathers.
Thank you for any help.
I need to order them asap, before my hubby finds out I have $$$ stashed away, lol. The good thing is that I have so much / many spare parts and pieces laying around, he will never know they are new! He doesn't know the difference between T5 and PC.
