@Tahoe61 do you have any insight on egg crate? I use the white ones from lowes.
I am not opposed to drilling acrylic though. Ive noticed a TON of algae growing on mine. So much that I just had to swap it out.
Update on the frag I dipped in chemiclean and put into established tank:
two polyps (the worst two) were eaten by mr crabs. The other two have not opened since being dipped so like a week? I dont have much hope for them at the moment

As of now, I am manually cleaning off the brown dust when I see it and it seems to be working alright. My palys are getting irritated by it but zoas are fine. I also have two mini colonies, bam bams and fire and ice, that have been closed for a few days. theres a few, maybe 5, that are inverted...maybe from messing with them so much.
I also ordered some brushes like the ones battlecorals gives away every so often. Theyre gun cleaning brushes oddly enough haha but those are in the mail too so now I will be able to clean more delicately rather than taking a toothbrush to them.
