MandoLynn-
Good stuff! Thanks for the response. I am 11 days in and have been following the cycling instructions to the tee. It has worked beautifully. We still have 2 white cloud minnows and they seem happy and healthy. The water is clear, the bubbles are bubbling and our 2 year old twins are fascinated with the "fishies".

I plan on taking the water to the local aquarium store again on Wednesday (free test day...nice!).

At this point, I still need to purchase a heater to ensure any further tropical additions are safe and sound. Once I do that, I am going to let each of the twins choose one fish. 2 is enough to start and I don't want to overcrowd my little ecosystem!

Funny side note:
I let the kids choose something decorative to put in the tank after I had it set up the way I liked it. Keep in mind they are 2 yr old twins, boy and girl. My daughter picked a Dora the Explorer pirate thingy and my son picked a tacky purple whale...Classic! Truth is those two additions give the tank more personality than I could have dreamed up.

Here's to toddler decorated tanks!!!

Feel free to send advice anytime. I'm learning and it's nice to have support so I don't screw it up.

Cheers!
