Tips on adding filter media from an established aquarium to a new aquarium?

Absolutely. If your water is clean enough in the 30 you can even take around 5 gallons out and put that into filling the 12.

Always helpful. Thank-you!

Nice Santa @Mama_Cakes
Beneficial bacteria will cut down the start-up time.

@Mama_Cakes You’re very welcome. Good to see ya back. How’s the tank doing?

It’s doing great. I have a pair of angels (getting big!), four albino cory cats, and a school of Harlequin Rasbora. No problems, so far. :)

I’ve been reading up on planted tanks and have ordered a Coralife Aqualight T5. Going to get into Baby Tears, Lugwidia, lava rock and all that jazz.

Thinking about adding a Golden Ram.

@Mama_Cakes Awesome, glad to hear it’s doing good. I like Golden Ram’s but I’ve always been more a fan of German Ram’s myself. Such beautiful coloring.
