NilocG Aquatics Aquarium Dosing Bottle | 500ml Bottle with Pump Top (Green 500ml Bottle with Black 2ml Pump)

These bottles are perfect for dosing fertilizer and supplements into my aquariums. No more guessing how much to add based on "a capful." With smaller planted tanks, figuring out fractions of a capful is woefully inaccurate. The pumps allow me to use only what I need for more consistent results and less waste. Tip: if you are using Seachem products, the labels peel off easily. I stick the labels on the outside of these bottles so I know exactly what I have.

This is just a single bottle for the price. My fault for not reading description. Just letting other people know.

It's a bottle that pumps. Nothing to write home about.The key bit is that is is pretty darn accurate! Purchased the 1ml pump. With testing up to 5ml, it's only a smidge off. Heck, for all I know that could have been user error.Wish there was something like this a long while ago!

A good pump bottle.

These are expensive but worth it. The pump truly delivers 1 ml per pump (I checked with a graduated cylinder). The pumps are smooth and prime with a single pump. The bottles are also good quality. I put all my ferts into these. Now, I ordered a different color and am going to put all my other liquid chemical into them. Worth the price.
