SeachemReef Calcium 250ml

As described, packed well, and does exactly what it says it will.A great addition to your aquarium maintenance.

My water is very hard but for some reason has very little actual bioavailable calcium. My mystery snails have really be struggling and I was looking for an effective way to directly add calcium to the water column quickly. I decided to try this out alongside a calcium water test kit, and used it to get my calcium levels up to 60-70ppm/L which is ideal for mystery snails and other snails. This is formulated to marine aquariums but it can be used in freshwater with some caution and a calcium test kit. A little goes a long way. Really helped my snails!

Good for fresh water if you have snails. Just follow the directions on the bottle

The best

I was running into issues in my snail tank during water changes. My tap water is very very soft and acidic, obviously not good for snails. I had them in a tub filled with aragonite and wonder shells but the time after a large water change I was noticing shell erosion since the water still took some time to harden up despite all the hardening products in the water. I started adding this calcium on top of my normal GH/KH+ and that seems to have done the trick! New shell growth looks perfectly healthy! I put it in these 2ml pump bottles and now water changes are an absolute breeze. I'd recommend the same if you have a lot of water you change regularly.

It's Amazon. Good product good price. Comes to your door

Sensei started using my corals are looking so much better.

Great stuff. I use this to maintain calcium in between water changes. I have monitored my dosing for about a week and found that in my system (93 gallon cube with 40g breeder sump filled about 1/2 way = ~100 gallons of water considering rock displacement) 1 cap is ~10ppm. Consumption rate will depend on your system an how many calcium using species are in there. Consider some magnesium as well.
