    Correlation between Alkalinity and pH?

    Hi everyone, I have a 300 gallon mixed reef system, and I am trying to make my tank a tad more stable/automated since I am traveling out of state for weeks at a time due to school. I am switching from a bubble magus dosing system (using biotech two part solution) to a korallin calcium reactor...

    Salt Brand Suggestion - Discussion

    Hi all! I like to support my LFS in anyway I can. One way is I purchase the salt they use. I’ve tested it’s Alkalinity and it’s bad. Not sure if it’s the batch because the salt seemed to have got moisture in it because it was hard but it did soften quickly when dropped on the floor like you...

    Has anyone tried the Red Sea Reef Energy Coral nutrition A/B ? What effects does it have on calcium and magnesium? How can the calcium and mag dip and rise without doing anything? Started dosing Alkalinity by Red Sea. Need to get CO2 to get my calcium reactor running. Who’s used a calcium...

    Concerning the Trident:

    Weather/Temperature and its effects on pH and Alkalinity consumption?

    pH: normally ~8.49 - 8.55, now its ~8.35 - 8.45 (apex, re-calibration confirmed accurate. As accurate as apex can be anyway. Rabble Rabble) Alk: normally ~9.2 - 9.5, now its ~9.6 - 9.9 (alkatronic, re-calibration confirmed accurate. Also confirmed with Hanna & Red Sea) Neither is a big...

    Rising Alk

    Hi, Over the past month, my alk keeps climbing steadily. I test the same time each week, and everything remains in line except the alk lately. Same salt since starting the tank over a year ago (RS Coral Pro). I change water the same time each week (10%). All rock has been in the tank for at...

    My New ReefBot cannot test 8 things. Only 4.

    So I just received my new reefbot. I am surprised to report that it cannot test 8 different things as one setup. I am able to test Alk. Calcium. Mag. And phosphates. So even though there are 8 vials in the machine some test kits require multiple reagents for a single test. I guess I will need...

    First time testing Calc & Alk. Calc seems high?

    Hi all, I invested in a couple of Hanna checkers for the first time! I have a 25 lagoon that's about 7 months old. It's all LPS right now, and I'd like to add some montis soon, so I tested both Calc & Alk today for the first time and they came in at 518 & 8.1, respectively. I double tested...

    Survival - not the TV show....

    Curious people are always buying frags - and every now and then (every other day lol:) there is a comment about 'the high prices'. So - I'm curious - what percentage of your frags actually 'grow into colonies - lets say 5 inches or more. How important do you think stable alkalinity is in...

    Can the GHL KH Director link with Apex?

    I see the Alkatronic allows you to connect to an Apex pH (via something like the PM1 module), for monitoring and keeping the data within fusion. Can the GHL director do similar?

    Trying to Maintain a steady alk for my sps.

    So the past few days I've been testing. In short, I tested the Alk initially, after three days, and after six days. It had averaged a drop of 0.166 dKh/day for both tests. I used the Hannah alk checker, along with my standard for assurance. Basically, my (130ish gallon) system went from 8.2 to...

    Alk Swing Crisis Averted...but my Torch Coral Didn’t Like It

    It had been smooth sailing so something had to test me to see if I was on my A-game right? I guess I had somehow shaken loose the acrylic tube from the bulkhead in my dosing container that contains my Alkalinity buffer. I dose 28 ml of Ca and Alk per night via my Jebao dosing pump spread out...

Last night, my alk was at a 7.2, magnesium was around 1425 ppm, and calcium was at about 520 ppm (This was after a water change that I did a day before). Tonight, I saw that my alk...

    Kalkwasser dosing

    Hi everyone. So I got my hanna test kit today to move from my regular dosing to just using kalkwasser with an ATO. My calcium is at 483 and alkalinity is at 7.2 which is alright for me alkalinity could be raised a bit but 7.2 is really fine for me. Should I allow my tank to go for a week...

    New to dosing kalkwasser

    I’m starting to have a large amount of lps and sps in my reef and just started testing for cal and alk. My alk is at 7 and cal is at 340. I’m looking into dosing kalkwasser or soda lime in my auto top off but I read that it can increase ph too high. Right now my ph is sitting at about 8.2-8.3...

    My APEX just dumped 200ml of alkalinity instead of 2ml

    Help....any ideas what to do? My APEX just dumped 200ml of alk into my 350 instead of 2ml. It shows 2ml as the dose but it has put 200ml into the tank when I look at the input. I just tested with Salifert and the dKh is off the scale low. How can I save my tank?
