Thanks for the help. It looks like some sand will get sucked up to matter what. My plan is to use the gravel vac and a tube. The gravel vac does a good job at picking up the light stuff. It just won't pick up the pleco waste. I'm going to use a rubbermaid container as a bucket. The 5 gallon buckets fill up too fast. I have noticed that the top of my gravel vac will pop off so I may try to use just that to pick up the pleco waste. I do have a water changer that hooks up to the kitchen faucet but I only use it to fill the tank. I don't drain the tank with it since you have to have the water on the whole time. I had 50 feet of hose and cut it to what I needed. I used the extra on my gravel vac. I don't use the gravel vac included with the water changer since it's so small.
