Hi everone,
Thanks for all your helpful information. I went to the store and got a shrimp and I am going to put it in, and not do any water changes until the ammonia and nitrite levels are 0.
Also the glass lid, it was for some of the fish that are jumpers.
about the gas exchages. i will countinue to reseach that and take off my lid.
On my 90 gal tank, it has an overflow on it, that is suppose to help with the exchanges, right? and if you have a sump with the bio balls in it that helps to. I also have a glass lid for the 90 gal, but I want a sump/refuge with cheato in it and no bio balls.
Carbon? on the skilter 250 refuge there is a black carbon filter pad in front of the skilter and the water passes thru that carbon and poly combo.
The carbon help with the yellow water and the smell. do you think the carbon pad is enough on the 20 gal?
any infor helpful, thanks.
