Brightwell Aquatics - Reef Code B - Balanced Calcium & Alkalinity System Water Conditioner - For All Saltwater Marine Fish & Reef Fish Tanks - Aquarium Water Treatments, 16.9 fl oz

Can't wait to use it I've heard nothing but good things about this 2 part.

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.

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!

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

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.
