Thanks for the salt and water advice i'll definetely use that for future reference, i think the smell is just from the fact that not only is it new out of the box, but it's that there is alot! of it, i must have 10 good size assorted plants with 3 resin ornaments, but the smell mainly comes from those plants, i think specifically from this real lush and thick 15" plastic plant they had on sale that looked good to me and caused this heavy plastic smell, i heard it might not be that harmfull or have any negative effects for the fish which i will take my time getting until that smell definetely at least reduces alot.
thanks for your help! i personally taught about mixxing some water and little bit of dirt to neutralize the smell lol! but i think i'll just wait and add alot more carbon instead since everything is already arranged.

Oooo charcoal is good too! And if you're doing any salt washing I'll tell you that I'v only used the non-iodized kind thats meant for adding to a fresh water tank...it says on the side of the box what ratio of salt to warm water to use. I just mixed it in a big plastic pail and let my new plastic plants swirl around for a few minutes then rinsed them out with dechlorinated water to get any salty bits off...I think the warm water helps draw out the chemical-ish smell or something...similar to how warm water draws tanins out of wood.
