Review: Exactly as advertised - Great little cones doing exactly what they're supposed to. They're about an inch to an inch and a half long. First 2 images are before, the next are after 24 hours of 1 cone in my 5 gallon. A few things to note before buying this: 1. The purpose of Alder cones is mainly to release tannins into the water column. Tannins have beneficial properties to the livestock in the tank and mimics some species natural environment to reduce their stress. Unless you have something like activated carbon or purigen in your filter- these cones will turn your water brown/tea colored! (Google blackwater aquarium- the colored water effect of this style is from a tannin source.) Removing tannins via chemical filtration also sort of defeats the purpose of adding the cone in the first place. If you don't want your tank to get very dark, you can either add fewer cones or get something that releases tannins less/more slowly, i.e Indian almond leaves, oak leaves, or driftwood, but it's still likely that your water will no longer be crystal clear if that's the look you prefer. 2. Adding tannins will drop your PH! For how much and how long depends on how much is added and what's maintained or removed, along with what kind of buffering capacity your water has- but please be aware of this and monitor. Especially if you already have livestock in the tank that may be sensitive to this. 3. Instructions on the package recommend 1 cone per gallon. That's A LOT. I'd recommend 1 per 5 gallons and add 1 more per 5 gallons after a few days if needed. As you can see from the photos, just 1 cone noticeably darkened my 5 gallon tank. I may add one more in another 24 hours but that will likely be more than enough to get the effect that I'm looking for. 4. The cones will float like driftwood does until water logged. I had a spare U clip and plant pot that I put the cone in and clipped it to the side of my tank to keep it underwater until it sinks. (Pictured) Again, awesome product and works just as intended. I love the blackwater look personally but it's not for everyone. Just don't rag on the seller because you bought a product that you didn't look into.
Review: Absolute tannin machines - I didn't bother reading the instructions on the backside like a dumbdumb because I thought these would be like many others - barely changes water color for maybe a week. Nope. I put 5 in a 10 gallon and 15 in a 55 gallon. Within a couple hours, both were the most delicious looking tea color I've ever seen my tanks. I put them in a basket and have them browning another 10 gallon as we speak. I did do my due dilligence and removed half. The gorgeous, nearly black darkness in my 55 gallon barely reduced my pH by 0.1 so people are freaking out for no reason. I have particularly hard tap water so these will help tremendously!

## Features

- Alder Cone As Shrimp’s Stress Reliever --- Our cones when immersed in water change the aquarium watercolor. Consequently, the tinted or the tea-water helps in shedding and the cones serve as a food source for your freshwater crustaceans.
- Lower Ph Levels --- The pH value in an aquarium varies depending on factors such as water hardness, trace elements present, and oxygen levels. Use our practical 50-pack of cones to lower the pH levels.
- Perfect For Shrimps --- The value pack of cones creates an ideal aquatic living environment for tropical inhabitants such as shrimps.
- Look Amazing In Any Tank --- The SunGrow Alder Cones add a raw beauty to the aquarium. Like cones produced by evergreen trees, the alder cones have numerous woody “wings” and are shaped like a Christmas tree. Before placing the product in the aquarium, always rinse under the tap water. A "post-boil soak" in fresh water is a recommended step too.
- Size Varies Between Half An Inch To A Full Inch --- Since these alder cones are not man-made, the size of each one would be unique. The SunGrow Alder Cones range in size from around 0.5” up to a full 1” (1.25cm to 2.5cm). As you get 50 pieces in one pack, they are enough even for the big shrimp aquariums.

PSA. Make sure to boil them. I started boiling them for an hour but when I put it into the tank, it tan it A LOT. Not an issue with the cones, it was me. So I boiled them for a few more hours with water changes in between. I also soaked it overnight. Much much better now. I also had to do water changes in my tank. Again my issue not the cones. They work and now looks great in the tank.
