no need to switch to t5's. especially if you can get 6500k leds for your set up. but i would play with the 10k's first. i know a few guys who keep planted tanks with 10000k bulbs. the plants grow nice, but it's just too darned blue for me. you'll just need to play with the dimmer for a few weeks to see where you get the most optimum plant growth. going to be a lot of trial and error there, i'm afraid.

it's funny, i too, am a fish guy. been keeping tanks for 30 some years, and it took a bit of adjusting. kind of like what? i don't need $10k in equipment? no way!!LOL so as i was reading your original post i was like cool, a sump. that would be awesome. wait, he wants to do what with a sump?? i had to read it a few times to get it straight in my head because the fish guy said yeah man, but the frogger was like, overkill!!LOL but hey, you're water can never be too clean, right??LOL i run a fluval fx5 inline with an ocean clear canister on a 75. my tank doesn't even look like there's water in it.....LOL so believe me, i understand over kill.

good luck with your build and if you have any other questions, don't hesitate to ask
