I C...
But can't you add T5s to the MH to change the color?? and don't MH come in different color temps? I guess the combinations could be overwhelming!!
I'll start re-doing my 28gal. again soon. I can't wait to get it done and with the new info I have gotten over this couple of years I'm pumped.
I was just thinking of the MH because I came across this fixture and it looked way too simple to me. I would just need a fan and a ballast transformer and done for not much money!!
There must be more to it..... Nothing is ever that simple

I was also thinking of the MH because of that "Twinkle" look at the bottom that I have seen and it looks so cool!! I wonder why I don't get that with my T5s?
Well anyway...... My 28Gal nano was used with a canister and want to go with an Overflow and sump, But I have that 28Gal. Bow Front Standard tank from the LFS and don't know if the back is tempered? Maybe you guys can help me with that info if you have drilled that tank.
Otherwise I will go with a HOB overflow and beg you guys for help

as to the correct flow rate and pump power, and size of sump tank in relation to the 28Gal. etc. That should be interesting!!

As for "BLUE"!!!
I forgot that I had a 5 gal. or 6 gal. Acrylic tank I think is the Eclipse that I never used for anything.... I got it used!! "SEE picture below from the web"
Well he is in it and it looks great!!! I got rid of the Bio-wheel system and added my Eheim canister rated for 60gl. and found out it came with a F8 T5 bulb that I'm changing out for a standard F8 T5 10,000K bulb!! hope that would be enough.
That's why I haven't posted pics yet!! I promise I will today or tomorrow!!

Sorry for the looong post but it has been a few days

Blue Looks happy and the best part is "HE IS ALIVE!!"

Post later today.
Thanks for the MH info more to think about and read

Will take the 28gl. slow as to not kill anything!! I hate that!!
