Makes the perfect nano ATO reservoir

2.5 gal tank and this lid and you’ve got a perfect small reservoir for under $30 that will fit where others won’t. Multiple hole choices accommodate whatever pump you’re using. Easy to fill rectangular opening in front. I love the combo, not so much because of the price( I’m using an osmolator 3 in it, so…) but because it’s perfect for what it is.
