    Should I switch salt?

    I currently use Red Sea Coral Pro salt which has a dkh of 11.5. I started using All For Reef on my 25 gallon mixed reef tank which I'm assuming has a dkh around 7.5 ~ 8.5. Is it worth the cost of raising the dkh of the All For Reef by addition of alkalinity? Or should I start using Red Sea's...

    ESV for alkalinity and kalkwasser for Calcium??

    Hi, so I’ve been using kalkwasser in my 150g mixed reef for the last five years. My alk is very low at 5.2dkh. calcium is 470 and mag is 1500. I started dosing ESV alkalinity to get the alk up. So my question - is there any reason i can’t doses ESV for alk and continue to dose kalkwasser...

    Alk creeping with auto water changes

    alright - I'm stumped on this. Tank is 3 months old, PH is between 8.1-8.2, Salt is at 33, MG is 1240, Calcium is 480 and Alk keeps creeping from 11 into the 12's. It got as high as 14, with Ca and Mg relatively the same. If I do a 30% water change, Alk drops some, I was able to drop it from the...

    Is it safe to trust our test kits?

    Hi Guys, I understand that hobby grade test kits are used more for reference and stability. I also understand that number chasing isn't always the best to do with our reef tanks. But I would like to share a story (photos included) and get your input. For years my hanna alk checker has been...

    New Frags - How Long Will They Last in Plastic Bags?

    I just picked up some Acropora frags from a local reefer and his alkalinity was 9.0. I just checked my current tank and I’m down to 6.8 dkh. How long is it safe to keep those frags in their bags (floating in my sump) until I raise my tank’s dkh to 9.0? Thank you.

    Alk and magnesium being weird.

    What would cause quite a big DKH drop and a raise in magnesium? The last time I dosed was a week ago, and it was Sodium bicarbonate for the alkalinity. I tested alk 2x to make sure...same result. I'm confused and worried.

    Kalkwasser stirrer: How to make it drip evenly?

    I have a Deltec Kalkwasser stirrer, and frankly the design is pretty much the same as most Kalkwasser stirrers out there. I feed it with a dosing pump, about 200 ml per hour. The problem is that the water level rises inside the Kalkwasser reservoir and suddenly squirts out several ml at the...
