Hands down, we have the fastest handling time and ship quick.

We over-staff so that your orders go out as fast as possible, if you order during business hours, we often ship it the same day. We ship everything(yes, even the big boxes of rocks you're going to buy) Priority or First Class. This means Packages get to you in 1-3 days if there are no delays from weather, holidays (although we have it worked out where we still get to ship most holidays,) etc.

Most other companies ship UPS or Fedex Ground. This saves them money on shipping, but who likes waiting for their products? We certainly don't and don't expect you to either so we pride ourselves in reducing time between you placing an order and it getting to your door.

Live Arrival Guarantee

We guarantee our live products will arrive alive. We ask that you do your part and minimize the amount of time our packages sit out in the elements. It can also be a good idea to avoid ordering live items during extreme temperatures. This would be when night time temps are below 35 and over 80 degrees during the day. Now these temps are not for sure death, it's just what makes it easiest for all of us during shipping.

When temperatures are cold we will use heat packs. Shipping live goods is difficult as our warehouse could be 70 degrees and your home could be snowing, and all the stops in between. We do our best and will make it right for you and may request to try again at a different time.  During heat waves, it's best to avoid ordering live goods as ice packs etc don't do enough to mitigate it.

**Special Delivery **Instructions

Our system isn't setup to take special delivery instructions such as "hold for pick up", "leave at back door" etc. We have many people working in the chain to pack your orders and get them out to you as fast as possible and the special instructions don't carry down the line unfortunately.

Our goal is to provide a fair way to satisfy our customers and not lose money while doing it. We make every effort to fully disclose how our products work and what is to be expected. A damaged product during shipping is an automatic replacement from us. When it comes to a difference of opinion such as: "My fish doesn’t like this food." That we don’t refund for. However, if you decide the light you bought is a bit too green for your liking, provided it is in the original box, within 30 days and purchased from us, we will refund it at your cost of shipping.

If you would like to return a product, start the process by emailing us at shipping@aquariumcoop.com This allows us to see if there is something we can do before returning the product such as a feature you didn’t know about or send you a return label. We don’t require an RMA number, but do ask you to contact us to initiate the return. Please do not call the retail store as they operate separately from the warehouse and will not be able to issue you a return label etc.

Products bought from http://www.aquariumcoop.com can be returned within 30 days of original purchase date provided they are unused,undamaged and in the original product packaging. If a product does not meet these requirements we reserve the right to deny the return if we feel that it is warranted.

Who pays for shipping? In the event an item is damaged during transit etc, Aquarium Co-Op will provide you a shipping label. If you are returning an item for another reason, it is your responsibility to get the item back to us safely. If it is a high-priced item we recommend a tracking number.

It is normal for plants to "melt" when they change environment. There are a few causes for this, one would be different water parameters. It is likely your water is different from ours and the plant will want to restructure and get it's roots in place to start taking in nutrients. This lag time can cause the plant to consume itself to keep itself alive during the transition.

Another cause would be a plant converting from Emersed(grown out of water) to Submerged(growing under water). This happen because the plant farms grow the plants above water in very humid environments. When we get them we start growing them under water. Depending on how long the plant has been in our care will be how much the plant has converted. The plants will always end up finishing this conversion in your home aquarium and would be considered normal.

Make sure you're fertilizing your plants. We recommend using Easy Root Tabs as well as Easy Green Liquid Fertilizer. Without fertilizers often times plants will die back.

Lastly there is a problem called "Anubias Rot". This is when the rhizome of an Anubias becomes mushy. This can happen when an Anubias is planted too deeply in substrate and it causes it to rot. This can sometimes be fixed by planting it properly on wood or rock. Then there is another case where the plant may have become damaged and the rot sets in and will consume the entire plant. This can happen at the farm, in our care, during transit, during planting etc. With no specific cause or who is to blame, we offer a refund or a reship of Anubias where this happens when it's been planted correctly and pictures have been provided.

When items go out of stock, generally we will try to get them in as soon as possible. We focus on limiting products that go out of stock. Sometimes with plants there is weather related events that cause delays, with manufactured goods, sometimes there are delays with shipping. The best course of action is to go to the product and put your email into the notify when back in stock. This will email you the moment we get them. Outside of that, employees will respond with "in the next month or so" as timelines are always as soon as possible unless something is outside of our control.


We generally like to run all of our tanks at a pH of 7.0 to 7.8. If you don't have this range it doesn't mean it can't work for your fish. It's just a great range to be in if your tap water is already there. We recommend not modifying it if you're already in this range.

If you are below this range, we use 1 pound of crushed coral sprinkled into the gravel for each 10 gallons of water to raise the pH slowly over time. This needs to be replaced from time to time, typically 6 to 18 months depending on how acidic the starting water is. If you wish to add crushed coral to your filter, know that it'll raise the pH faster, but also run it's course faster.

If your pH is above 7.8 and you need to lower it, unfortunately that is a much harder task. We recommend using an R/O filter if you absolutely must lower it. An alternative would be to use a planted tank and stop changing water. This will lead to acidification of the water over time. When the water gets to the level you'd like, you can then do very small water changes periodically to maintain that level and safe parameters for your fish.

Unfortunately we don't sell fish online. We are looking for the right business to pair with that offers an affiliate program that we can refer people to. You can watch the video below on an explanation why it doesn't make sense for us to ship fish.

At this time we don't sell any of our products wholesale. We don't have the infrastructure setup to ship pallets of products to different stores.  If this changes in the future, we will update this article.

We don't disclose our vendors. This helps us remain competitive. Also for individual stores, proximity to vendors, water parameters etc all play a part in which wholesalers will make sense for you to be purchasing from. Our best advice is to attend shows, and always be seeking other suppliers and constantly track your pricing so that you may improve it over time. No one starts with great pricing, without proving to the supplier the volume they can move. With time more vendors will approach you.

We often get asked, how do I chat with Cory on the live streams? Or when do the live streams happen live?

We live stream every Wednesday at 5pm Pacific Standard Time when Cory is in town. You can click here to see all the videos and upcoming live streams.(live streams are usually scheduled the day of)

To chat with Cory and everyone else, open the video while it is live on a device that supports chat. Not all devices do, but all computers and laptops will, most phones etc. There will be a chat box that you can open up. From there you can type 1 message every 60 seconds. With thousands of people watching do know that it's hard for Cory to see the messages as it's kind of a lottery system. However other chatters will usually respond to questions as well.
