Replenish, 100 mL / 3.4 fl. oz.

SeaChem products are the best. I use Replenish when adding Distilled Water or Reverse Osmosis water to Aquariums. Adds essential minerals lacking in these two water sources.

I had issues with keeping shrimp until I used this. Dechlorinated and heavy metal neutralizing additives didn't work, and RO/DI didn't work. I started using this with RO/DI water and now my shrimp are flourishing. I now have second generation shrimp in my tanks!

Everything from Seachem is amazing including their customer service, product and hobby knowledge, and responsiveness.

This stuff is amazing

Excellent product, but be cautious when using. I tried half the amount in my 35 ltr tank, and that was enough to bring the balance back.

Great at helping mature a biological filter very quickly and keeping it stable. I have cycled 2 marine tanks in 7 days going from really high levels of ammonia to zero in 7 days. You must have ammonia in your tank before adding this product, otherwise it cannot do anything, ideally you want high readings (assuming you are not using fish to cycle your tank which is very cruel and unnecessary practice).You can purchase ammonia specifically for this purpose, if it’s a reef tank and using live rock die off will likely give you enough to start the system or you can phantom feed the tank or add a raw dead prawn, once you have a nice strong reading for ammonia start adding stability and continue daily until levels drop to zero and continue also while adding fish to support the filter. Again please do not use fish to cycle your tank if anything it is an impediment as you cannot allow the ammonia levels to get to high levels with living creatures in the aquarium which means you will have a very limited amount of good bacteria in the end of your cycle which is more likely to crash once you start adding more livestock and the fish you have used will suffer and either die or be permanently damaged as ammonia burns their gills.
