Is this to prevent any damage in the future for the turtles or is this for the turtles while they already have some kind of calcium deficiency? My turtles are still babies but I want them to grow healthy. Should I buy this now or wait to they grow older?

Answer by ChewySep 26, 2019
The Zoo Med Dr. Turtle Slow-Release Calcium Block Turtle Supplement can be used to help prevent issues as well as treat some soft shell issues. It can safely be used with hatchling turtles.

Is this product safe if my turtle were to consume it?

Answer by ChewyJul 09, 2019
This supplement is safe for turtles to eat.

how long does it last? I'm considering this for my aquatic snails.

Answer by ChewyJun 07, 2019
The block begins to slowly dissolve once placed inside the water. The duration depends on the water temperature of the tank.

If I use these with yellow bellied sliders, do I still need to use the calcium powder when feeding them?

Answer by ChewyJan 26, 2022
The slow-release calcium block can be used with yellow belly sliders, it will help add calcium to the water which they will consume when drinking. However, Zoo Med does not recommend using a calcium powder when feeding them as it can just foul the water. Make sure they are being fed a balanced pelleted diet with added vitamins and minerals.

Love these

I put one in every month or so, just for extra calcium for her shell and never had any problems. Her shell stays firm and nice!

Turtle enrichment

My turtle loves to pick up, bite, and eat this thing. It’s her favorite toy. No idea why, but it’s cute to watch her “fetch” it when I throw it into the water

Easy to use

I use this in all of our freshwater fish tanks. It helps keep the hardness inline for the fish we keep. When it’s gone, replenish.
