For that size tank, I would recommend two hydra 26HDs, however they are way over your budget. One will not suffice, I may have two for sale next year, however I would want 10k for both minus the mounts. However for yor build, if you want to keep it budget, I highly recommend the zetlight 7300 or the qmaven 2 6600, both are amazing lights. I ran both of them, if you after better spread go for the 7300, since your tank is quite wide I suggest this. If you want better coloration I suggest the 6600II. The QMaven 2 may be over you budget. I sold my for 6000 last year. Overall I recommend the 7300 for your build, it’s controlled via wifi and is a real powerhouse 200W. Or if you interested in my hydras 26s we can chat next year. There are also way cheaper alternatives out there, but I suggest you don’t skimp out on lighting, you will regret it later. Hope this helps.
