ok, i will stick to my separate bottles and keep measuring everything.

hum... i didn't realize that phos sponge was so nice to have. i was reading the container and it was talking about getting hot, and the way it sounded i was a little nervous to use it. but i guess i'll just keep it then and give it a try once i get my big tank set up. my 29 doesn't have a sump, so there wasn't much need for it. or so i thought.

thanks again everyone, and merry christmas!
