alkalinity

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...

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...

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...

Since I tore my reef down, I no longer have use for these. $40 shipped - 2 sets available. ***SOLD***

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...

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...

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?

We sold out of the Neptune Systems Trident in about 10 minutes this morning. The good news: we'll have more on the way soon! If you're interested in picking up a Trident, click the "notify me" button on this page and we'll send you an email once they return: https://mdshop.us/Trident

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...

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...

I've been dosing Brightwell Aquatics Reef Code A & B for about a week now. Learned that I need to dial up my dose but also wanted to bring my Calcium and Alkalinity up generally, and in reading the advanced instructions I'm a bit confused. Reef Code A (Calcium) instructions read: "If the...

Hey Reefers! Today we've got a quick fix to changing over from dosing 2-part to your tank to running a full Calcium Reactor setup. Through the help of Jdieck's Calcium Reactor Calculator Ryan explains how to test your effluent, input the data into the calculator and dial in your dose to...

Hey all, i tested my water last night and tonight to see the amount i need to dose for calcium, alk, and magnesium. 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...

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...

How to Use Hanna Checkers to Dial In Your 2-Part Dosing Regimen VIDEO: A beginner’s guide to maintaining calcium & alkalinity

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...

Coral health? Mostly ok (a few birdnests flew the coop) Coral growth? LPS very nice, SPS pretty ok Don’t like Vermetid snails? Yes, though irrelevant for this post Allergic to cats? Yes Does size matter? 120DT / 200 Total ALK 9 CALC 380 MAG 1500 Brand shout out: reef crystals 2-part dosing 25ml...

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?

Since R2R has been such an amazing source of knowledge for me through out my years in the hobby I want to share this idea with you all. It was originally posted under the chemistry forum for discussion but this has now become quite the DIY project and I think this is a more appropriate place for...

I was reading someone's post highlighting some of the most successful tanks owned by many of the big coral companies. The parameters were all over the place in terms of calcium, magnesium, nitrates, and phosphates... kind of showing that stability was the key. But, 9 of the 10 tanks kept...

My alk Rides between 7- 7.6 and calc around 420-430. I have been using kalk in my ATO to maintain calcium and alkalinity levels and my SPS have been growing nicely but I feel like its not as stable as it could be. My 75g evaps about 1 gallon/day. I like the idea of adding 2 part to get my alk up...

Hi FAM: I tested on Sunday Before Water Change: 97ppm = 5.42dkh Sunday After Water Change 122ppm = 6.82dkh Thursday four days later I now have 104ppm = 5.81dkh 1-Does anyone know how fast and or what should I expect as far as decreased ALK parameters after just four days? 2-Should I start...

Hello, I have been learning about calcium, alkalinity, and magnesium in a reef tank, now I am learning about ph. What is a way to raise ph in a reef tank without messing up the other perameters: calcium, alkalinity, and magnesium?

Hi all, I wanted to preface this by saying that I love using the aqua forest component 1/2/3+ and have had great results, however, I am going through $80-$100 of additives a month right now and am constantly having to refill my dosing containers every few days. So I was planning on...
