Water Care

Pools

Hermit crabs require a salt water pool AND fresh water pool. Pools should be big enough for your largest hermit crab to fully submerge. There must be easy access for them to get in and out of the pools so they don't drown. We always recommend The Lucky Crab Co pools. They are 3D printed and made for hermit crabs and come in a variety of sizes to choose from. They have little stair cases for an easy entry and exit, and have a built in bubbler system!

Pool Trays are a little addition that can make a BIG difference. Place your pools on top of the pool trays, so when you take your pools in and out to clean, the pool trays keep the substrate underneath from being distrubed. This can help protect molters underground, and not let their molting interfere with water pool maintainence, and vise versa!

They are made to fit The Lucky Crab Co's 3D pritned pools, but you can place any pools you may already have on top of the trays!

Fresh Water

Use tap water and add Seachem Prime. Tap water has beneficial minerals, and the Seachem Prime removes the harmful chemicals in the tap water. Seachem Prime is a MUST to make the water safe for your hermit crabs. Seachem Prime should be used in both fresh and saltwater pools.

*One drop of Prime treats a 1/2 gallon of water.

Salt Water

Get an empty gallon jug of water and fill with tap water. Add 1 cup of Instant Ocean. Shake well and use as needed to refill saltwater pool. Add your Seachem Prime drops in saltwater pool as well. 

*1/2 cup of Instant Ocean per gallon of water.

Bubblers

Adding a bubbler system to your pools is a great way to keep your hermit crabs water fresh for longer, add enrichment, and can help aid in higher humidity levels. 

Bubbler Supplies (air pump, aquarium tubing, check valve, "T" divider, bubbler stones)

*The Lucky Crab Co pools come with a built in bubbler system, so you would only need the tubing, air pump, and T divider!

How to Set Up Bubblers

Pool Maintenance

If you have bubblers, clean out your pools once a week. If you do not have bubblers, clean out every other day. Dump and replace water, can use toothbrush to get in grooves and help scrub off any grime. Use paper towel to dry and wipe off grime as well.
