I have saltwater fish and coral for sale and will be expanding on freshwater livestock and aquatic plants. We also carry exotic and predatory plants. Our goal is to set up and/or maintain aquariums for people at an affordable price. We want people to have something that they can be proud of as well as to take the hassle out of having to worry about the health of their animals.

Tips for potential power outages!
Always make sure to have good working air bubblers and plenty of batteries on hand. Check that your heaters and temperature controllers are working correctly and have no cracks/compromised cords etc. The adhesive backed body (hand) warmers work well to trap heat in the tank from the outside panes of your aquarium. And as crazy as it may sound, cooking grade or Pyrex glass containers. Not only can you heat them, but if they have good sealing lids you can heat the water and submerge them in your tank to try and temporarily regulate tank temperatures. (I actually had one customer who would heat the tank water in his Pyrex bowl with a candle and it saved all 4 of his clownfish)
And just to try and relieve the stress and worry do yourself a favor and undo all canisters on your RODI unit and empty them. The membrane canisters can be tough to get open so one little trick is to just undo the tubing as to relieve pressure as the water will expand, if it has no where to go it will cause a crack or failure.
Remember it's not stupid if it works! Good luck everybody, I don't think this storm will be that harsh but its better to be prepared than to have a complete loss over something that could've easily been prevented with minimal effort.

ATTENTION!!!
**Don't forget, this Sunday 6/23 we will be hosting an equipment swap meet. Gonna try and beat the heat (as best as we can at least) so if you want to show up a little early at 11:30 a.m. with your gently used equipment that may be your best bet.**
Rules are as follows:
1. Equipment must be in good working order and have all parts unless it is clearly stated to the person interested in what you have.
2. Any deals must be made between the seller and buyer of said equipment. Purchases are made "as is" (unless completely inoperable) and MAC's Tanks will not be responsible for refunds or exchanges unless it is equipment purchased from the store not an individual.
3. No alcohol, or illicit drugs will be permitted whatsoever.
4. No smoking or va**ng in store whatsoever.
5. Smoking of any kind must be done outside of the store in the parking lot and must be away from any entry ways or roll ups doors of any other businesses.
6. We are asking that if you do decide to make any livestock purchases, after the transaction is made you make your way to the storefront or wherehouse. We are trying to cut down on crowding in the store and to make sure any and all customers are as comfortable as possible.
7. Theft/harassment/bullying of ANY kind will not be tolerated whatsoever. MACs Tanks LLC is under 24 surveillance inside and out and if something is brought to my attention this will result in a PERMANENT BAN no questions asked. This will also include notifying authorities as well as mentioning to the administrators of all public and private forums of the incident.
(Don't ruin your reputation to try and save a buck, it's not worth it.)

*ATTENTION*
Due to the holiday we have decided to push back the swap meet for equipment to June 25th. This will be the following Sunday not this weekend. With Father's Day landing the day after the originally planned date we want to make sure as many people are able to attend as possible. (And first and foremost to make sure you are able to spend time with family members!)
We're currently adding more systems to the store and want to make sure this event is better than the last!
Sorry about the short notice, keep an eye out for updates

So I got attacked by a pack of tigers...

Food training almost done, getting ready for it's new home! No fish that's not eating will be sold at the store... Period
Let the food training begin! All "sensitive/picky eaters" are conditioned to accept a variety of foods. Guaranteed your new additions won't starve. No fish that refuses to eat is for sale... Period! (And yes I had to go back in the tank and adjust the rocks since these little guys are such vigorous burrowers smh)
Shop tank looking good tonight... Disregard the dirty glass #macstanksllc #LFS #smallbiz
