I use PVC, tie the bottle inside to the PVC and drape the PVC out the back on some tanks and over the front on other tanks, using a Platic Zip tie, works great. It's work but I only have to refill my small Gatorade bottles every 2-3 days. It depends how you place the bottles in the tank, how many plants you have and how large a tank is. I recommend this approach as you will learn from it and it has its pros and cons, but caring for your tanks is part of the hobby I enjoy. My plants definitely like it.
