Brightwell AquaticsReef Code B - Balanced Calcium & Alkalinity System Water Conditioner - For All Saltwater Marine Fish & Reef Fish Tanks - Aquarium Water Treatments, 67.6 fl oz

The media could not be loaded.  I dose with Kalkwasser for foundational CA/CACO3 needs because I don’t like adding the extra salts required in basically every other CA/buffering tech, but my system is long-passed sustainability on ‘limewater’ alone. But I do find the Brightwell carbonate supplement easily, reliably, and safely bridges the gap.

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!

Quick delivery, great product for saltwater tank

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.

Brightwell is a great product use nothing else but thier products for reef tank and this is a great price for thier product and last months in my 55 gallon great deal for your buck
