Atlantic Rush Vacation Feeder for Aquarium -14 Day Feeding Blocks (2)

How should I store the blocks, and how long do they keep?

Store unused blocks in a cool, dry place at room temperature, sealed in their original packaging until you need them. Keep them away from humidity and moisture so they don't soften or start to dissolve early. Stored this way, they'll be ready whenever your next trip comes up.

My block didn't dissolve — or dissolved too fast. What happened?

Both come down to your tank's conditions. If it dissolved too fast, it was likely in strong flow or warm water, or too many blocks were used — next time, place it away from the filter outflow. If it barely dissolved, your water may be cool, hard, or alkaline, or your circulation may be too gentle — a little more water movement or warmth helps. A test run shows you which applies to your specific tank.

How many fish can one 14‑day block support?

One block is designed to feed a typical tropical fish aquarium of up to ~10 gallons with 5‑10 medium fish for 14 days under normal conditions.

Is this block safe for both goldfish and tropical fish?

Yes — it is formulated for freshwater aquariums and is safe for common goldfish, tetras, barbs, guppies, and most community fish species.

Does it alter water pH or clarity?

No — the slow‑release formula dissolves gradually and is engineered to minimize clouding and pH shifts when used as instructed.

How soon before travel should I place the block?

Place it right before you leave. If possible, place it the day you leave or earlier in the morning of departure so fish have begun accessing it, and be sure to test water parameters the day before you go.

Can I use this in a tank with a power filter?

Yes — it works with filtered tanks. In fact, good filtration and aeration help ensure the block’s dissolution is controlled and water conditions stay stable.

What size tank and how many fish is one block meant for?

One block is intended for a lightly to moderately stocked freshwater tank of about 10–15 gallons. For a larger or more heavily stocked tank, you may need a second block — but add it gradually and avoid overloading a small tank, which can cloud the water. When in doubt, fewer blocks and a clean tank is safer than more blocks.

Do I need a filter or air pump for this to work?

Yes. These blocks rely on gentle water circulation to dissolve evenly and release food. In a bowl or a tank with no filter or air stone, the block may simply sit there without properly feeding your fish, and any food it does release can settle and foul still water. A running filter and/or air pump is recommended for best results.

Is it safe for snails and shrimp?

The block is calcium-based, and many snails and shrimp will graze on it as a natural calcium source that supports shells and molting. That said, invertebrates are more sensitive than fish to changes in water quality. If you keep snails or shrimp, use the block only in a filtered, well-circulated tank, avoid overusing blocks, and check your water during a trial run before you rely on it for a trip.
