You can always add strainers also to help prevent fish or snails taking a ride.. A tone of options... JUST get one that fits over the drain pipe so it doesn't reduce the opening further .
Thanks for the responses and help. I agree about the small drain with a valve will cause more restriction. I laughed at your response because of these two sentences! It's slowly getting there. We finally agreed on a spot where the tank is going!The suspense in your plumbing is really starting to build..!! Grabbing a bag of popcorn now and waiting for you to turn on the waterfall!!

Now to get it into the spot, redo some electrical to protect the outlet, level it out, fill it, and test out the drains.
After hearing to use the small drain as the primary, it definitely messed with my understanding of how they designed the tank. I'm still stuck on using the larger drain on the primary.
@Coral reefer I get what you're saying about not even using those drains and start from scratch with new overflow. Or get a different tank. We're doing this hobby on a strict budget to say the least. So we're trying to not go crazy with additional purchases. I have seen in other forums, some kickass setups with this tank, plumbed the way the way they intended it and sold to customers. That's why I keep going back to why not use the larger drain as the primary. Just trying to make this work with what I've got the best I can.
