Brightwell AquaticsReef Code B - Balanced Calcium & Alkalinity System Water Conditioner - For All Saltwater Marine Fish & Reef Fish Tanks - Aquarium Water Treatments, 8.45 fl oz

Always been using this brand, Brightwell Aquatics. Requires the lowest dosage by volume compared to other good brands on the market as much as I know. Maintains Alkalinity stable, through an automated doser. Had to make a week’s adjustment on my tank’s requires daily dose and finally got it to stabilize. Remember that having a GFO requires more doses of this supplement since Granular Ferric Oxide lowers alkalinity, scrapped my GFO reactor so I use less Alk/dKH additive. Got a lot of macro algae to deal with the Phosphates (PO4) and other nutrients in my tanks’s System.This is the best and the only product I use for Alkalinity adjustments!

Went and filled my dosing container up and realized their was a solid block calcified in the bottom. So not sure if I'm getting the correct dose so I stopped using it and ordered all for reef wasted the money buying it.

The package was delivered at the end of the shipping timeline, but did arrive on time. The bottle was inside a plastic bag and the box was marked appropriately.Major disappointment to find that the bottle was not factory sealed. Once I removed the bottle from the bag, I noticed the white seal was not attached to the bottle; it was in the top.

Excelente

To keep parameters perfect these are a must have ( A&B ) solutions.

I use this along with Reef Code A to keep the parameters healthy for my corals and saltwater fish.

I use this, along with Code A to keep my saltwater tank healthy - both for my corals and fish.

I've ordered the reef code A & B. Both bottles weren't sealed & leaked all over. They were double bagged so I guess it was expected to leak.
