Brightwell AquaticsKalk+2 - Advanced Kalkwasser Supplement 100g / 3.5oz

this stuff is awesome! helped fix my PH issue that reef crystals was causing me. I now use neomarine salt from brightwell and my PH is better than ever and i have good coralline algae growth on my rock and glass and my sps has never looked better! I just put a few teaspoons in my top off container and mix it up and when my auto top off kicks on it doses it for me multiple times per day to help keep my levels from depleting and help keep my PH where it needs to be.i have a 60 cube with 20g sump and glass top so i dont evaporate much (maybe 5 gallons per week) so knowing that i suggest getting a larger size container. this one lasted me about 2 months only.

Just started using. More to come

Does the job

This product is amazing! Corals are finally getting what they need and PH is spot on using this in a drip system. Shout out to Jake from Reef Builders as he uses this product, follow his youtube channel.

Wonderful

Great for dosing in your RO water, it maintain my PH, Kalk and calcium to good level without having to calculate the dosing. A little on the pricey side so 4 stars.

Excellent

I like how well it fully dissolves into rodi water and leaves no setiment at the bottom of my buckets.
