20gal Questions.

I'd get MH's right off the bat,if you didnt already have that light.20 high tanks need MH in my opinion,especially if your planning an RBTA.Also find a small clone because they grow pretty big and quick!Its good your going to go slow,i wouldnt add the anemone for 4 months imo.The water acually seems like a good deal considering i pay 2-3 bucks just for a 5 gal of RO/DI water from safeway! Lastly you dont need a skimmer but again with an anemone in a small tank it will greatly help with water quality.

If your just going softies your original plan seems fine.Ive acually done the bta in a small tank (18g) with MH light and skimmer and it was happy and never moved.
