I used pond foam (its like Great Stuff but for ponds) to seal my rocks so my water would flow. I have one large flat one on the bottom level. For some oxygen for while you work on the falls I jst used an aqarium pump with an airstone on it. I cut a plastic coffee can to put the pump in to protect it from the weather. We rebuilt our waterfall 5 times!! so have some patience.Your water will flow better after you seal the cracks. Good Luck!

Thank you everyone for following up on my Iris' pics. I'm definitely new at this and to have some bloom first Spring after planting them and to be so BIG, well that just fascinates and tickles me! I wanted to post a follow up to my pictures. Those other pictures were taken yesterday and when I went outside at 6:00am today (EST), I had the most beautiful surprise waiting to greet me on my front stoop (porch), see for yourself....

Hattrick, I got that in Pittsburgh. Dont know if you live here, but with a name like yours its possible! There is a nursery right next to North Park, not far from Passavant Hospital. I don't live in that area so the name escapes me. That was 2 years ago, and if everyone got the same results as me, I'm betting they don't carry them anymore.

worldmom - that is really amazing! Looks like we will have much in common! Here are a couple of shots of our frig wall As our micro will sit on shelf above, the bottom drawer is actually a built-in step, ostensibly for the 5 y.o., but since I am short I was happy to have a quick way to reach those "to the ceiling" uppers. jej, vic, plucky and rhome -- thank you! We are blessed to have such a large space and I can't wait to have family and friends fill it up! We cook a lot with our children and it was so great to see my 9 y.o. son come through the space last night and make a bee line for the ovens, studying the controls, opening the doors and commenting -"wow, we can cook like 9 things at once"! jej and caroline - I will look forward to both the cooking and decorating sessions! rhome - really apprciate your comment as you, in particular, offered many design, organization and layout ideas (whether you know it or not) just from reading your experience. One that you see above are the Electrolux Icon frig and freezer! I remember how thrilled I was to find that info as I knew I wanted separate units and these met my parameters beautifully! Am now anticipating opening them and actually seeing food in there
