Yea I use the same mesh for my dividers along with poster borders. The only other non-fish tank stuff I'd use are polished stones or glass beads that dont have any wierd residue on them.
So I want to turn my sorority and 10gs into planted tanks (okay maybe not Seiya's, I"m done fighting with his tank he can live happilly with silk plants and his log), and beginning to think maybe I should grow my own plants. I mean, if I got a 20g, planted with soil and sand, then used it just for growing plants, I'd have a decent batch I could share between my tanks - yea? It could even sit on the floor, or just a plank on the floor, so long as I had the right light and stuff. I'd prlly go the CO2 injecting root along with Seachem Flourish and iunno whatelse.
Just thinking this might be easier than ordering plants for years to come, right? And then there won't be that risk of disease transference. Not that I'm worried about that from you LG =)
