Reddit mentions of Python Pro-Clean Aquarium Gravel Washer/Siphon Kit, Medium with Siphon Squeeze

1. Air pump looks fine. I am personally a fan of the Tetra Whisper pumps...they are just really quiet. On that note, get air valve like these (https://www.amazon.com/Jardin-Aquarium-Control-Single-4-Piece/dp/B00880E10E/ref=sr_1_4?ie=UTF8&qid=1491410374&sr=8-4&keywords=aquarium+air+pump+flow+valve). This will be your main method of controlling the flow into your filter.
   
   
2. Good job choosing the master test kit. Like it was said before, those strips are absolutely worthless :).
   
   
3. My main reason for responding. The heater you have chosen is not only a good size for your tank, but I personally always recommend getting a heater that has a wattage that is for a larger tank than what you are using it in. The reasoning is simple: A higher wattage heater has to work less to keep the water temperature stable. That means it is on less, and has less stress on it over it's lifetime. Furthermore, IF a heater malfunctions and fries your fish, the wattage is not going to matter. You are most likely not going to be staring at your thermometer and wont notice that your temp is going up soon enough to save your fish, regardless of heater wattage.
   
   
4. Great idea getting an analog thermometer. I would also pick up some of these: https://www.amazon.com/gp/product/B01N9663GI/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 . They are cheap and it is nice to have a second way of checking temp to confirm.
   
   
5. Gravel vacuums are not all created equal. I live and die by Python products. And this one is a third of the price of what you were going to buy: https://www.amazon.com/Python-Pro-Clean-Aquarium-Gravel-Squeeze/dp/B00BDPFYEI/ref=sr_1_3?s=pet-supplies&ie=UTF8&qid=1491410615&sr=1-3&keywords=python+gravel+vacuum. You will need to get a piece of tubing to connect to the output but it is extremely cheap at any hardware store.
   
   
6. The lighting looks fine.
   
   
7. The filter looks fine, I only really use hang-on-back or canister filters so I can't really offer an opinion on the filter you've chosen.
   
   
8. Seachem Prime is the shiiiiznit. Best water conditioner out there.

Yeah!

Skip to ~3:00 to see it in action here with gravel https://youtu.be/G4Zi1g5vvYs

My guess would be that it could work with sand too, since sand is heavier than poop

Buy an aquarium vacuum/siphon along with a bucket or get a hose long enough to go outside.

Would this work?

I don't have a small siphon since I intended to do water changes with a cup.
