I added some red ludwigia and put my DIY c02 in this past weekend.
I am hoping the staurogyne does ok with the stock light, ferts and c02, but will consider either the Finnex or Fluval perch light in place if they start to suffer. I do like the Finnex as it also has the moonlight built in on top of the CFL.
@ Jamesyu, Based off of when you had your Evolve running, did you find the filtration to be sufficient with the stock you had? I already added a bag of biomax for an AC70 along with some filter foam (and purigen/existing biomax and media from my current tank.) I had seen the Zoomed 501 on sale at Petco, and was considering getting one as I have rewards to use by the end of the month.
