I just switched from a gravel substrate to sand and I love the way it looks now. I have a question about water changes, as to how I could syphon the water without syphoning out my sand while I'm at it. Is there a sand filter I can buy or make to prevent my syphoning tube from sucking it up along with the fish doo doo?
Also, I need ideas as to how I can create more water movement in my tank. As of right now, I have a Whisper 4.0 for my 35 gallon tank along with a bubble wand. Is there anything cheap I can pick up to drastically create water movement?
