alkalinity

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...

I've had my tank setup with corals for about a month now. I added 15 new coral frags that I purchased from world wide corals. These include 4 SPS, and the rest LPS (duncans, zios, ricordias, Lords, torch, hammerhead, and a couple chalices). I am using Instant Ocean Reef Cyrstals for my salt...

With all these alkalinity monitors and related equipment that are already on the scene, I was wondering if there was any work being done on an actual sensor that did not require titration. I know Seneye has something coming out, but that appears to calculate the carbonate level using CO2...

Since my calcium reactor cant seem to keep up with my alkalinity needs, would it be feasible to dump some kalk into my saltwater container? I've implemented automatic water change of about 7500ml/day. Would there be issues like clogging the lines, burning up my DOS, screwing up the chemistry?

We all know (I think ) that alkalinity should be kept as stable as possible. However there is little information on what 'stable' is so I am starting the poll to see what change average reefer see's on a daily basis when they test their tank. Would be interesting if you added a post to say...

Pickup at East 92nd & Clarkson in Brooklyn - call or text 7184504701 ESV 2 part, 1 gallon of alkalinity and calcium. I mixed up but used very little - $20 UltraReef Reactor - used for 4 months, purchased from UniqueCorals - $110 - I bought it from Uniquecorals.com -...

Changed to a Kalk Rx after 10+ years of running a CaRx on a 250g Mixed Reef system (fish, SPS, LPS, Soft, etc), tank pH had run 7.8 to 7.95 with Alk running 9.5 to 10.2 kh. Currently, with a Kalk Rx, the pH is 8.05 to 8.15 with Alk at a steady 8.3 kh dosing 2.03 g/day across 48 - 3.5 min...

So I'm looking to add an alk and calc doser to my 32. Any suggestions on which one I should get? Thanks so much and as always, Happy Reefing!

I recently got a dosing pump (finally), but I'm having a hard time finding out how much Reef Builder powder can be added to a mix stock solution. I'm going to be using a 2000ml container, but how much powder can I add to the container? Seachem website is not helpful at all (I don't care about...

Why does my alkalinity slowly drop in a tank with no corals? (approx 0.4dkh every 4 days) Ca Mg is constant at the moment. I have restarted my tank and through the cycle is finished I currently have an algae bloom. The tank just has 7 medium sized fish, cycled rock and sand (originally dead...

Hi, I have one lightly used "BRS 2 Part Doser - 1.1 ml Per Minute" for sale. I used the pump to dose Alkalinity to my nano tank for about 3 months, but recently replaced with a 4-head dosing pump. It ran ~45 minutes per day during that 3 months, so the pump has a total run time of about 70...

Have been experiencing low alkalinity with my sps dominant mixed reef tank. Any suggestions as to what I should do? I was wondering if it is possible the current calcium reactor is too small. The tank is a red sea 525XL (525 Liters) plus about 50 gallons of sump. Current alkalinity is 6.1...

hello all as the title says I have another PH question. butt you can see by my picture my ph runs between 7.5 and 7.7 it goes up as high as 7.9 after water changes( indicated by red circles) . I live in a condo with myself and my wife. On a regular basis my ph will drop to around 7.4 at night. I...

Does Hanna offer calibration fluid, so I know my Alk checker is reading accurately. And if so, and the reading is off, how to calibrate? I'm using the HI 755 ppm Alk checker with the HI 755S reagent

Hey everyone! There has been a lot of talk these days about the options of automated Alkalinity monitors. The benefits of these is easily seen but the price tag, other required controllers, and honestly the looks of some of the options out there have me reluctant to invest quite yet. So I got...

I currently have slightly low alkalinity between 6.4 and 7 and high calcium (a little over 500). Things in the reef are thriving. I have heard you can set the reactor for the desired alkalinity and the calcium will fall into proper range since it’s all about balance. pH is fine (maybe a...

So my RO/DI water is very weird. The TDS comes out at 2-3 ppm (due to terrible water), but also comes out with high carbonate hardness, which is 8-9 DkH. Right now my water is 3 ppm and 8 DkH. This test has been done by many test kits, including the LFS testing it. However, according to @Randy...

So my alk. is about 17 dkh, which is really high. Even though it's a macroalgae tank, I do plan to put some bounce and jawbreaker mushrooms in there that I have in QT. I heard muriatic acid (or hydrochloric acid) is a way to bring down alk., but I don't know the dosage. I want to bring it down...

okay, so Sunday I realized my tank was in trouble. I should have found out sooner, since one of my corals started looking unhappy by last Thursday. I tested my calcium and got 330 PPM. I'm trying to keep it at 450 PPM, but by Monday it dropped down to 300 PPM. Turns out my Apex was programmed...

Ok everyone, i need some advice/help with my frag tank. I am not seeing very good growth. Most corals seem ok but not flourishing like I would have hoped. I am wondering if PH is the problem??? First a little info. Tank is a 45 gal peninsula ( approx 12 inches deep) draining into a 20 gal...

So the other day I got some erroneous readings on my Salifert alkalinity test. First one was 9.6 dKh then two days later it was 12. I also tested a fresh batch of Reef Crystals and it came out 12 dKh. I panicked but everything looked healthy in my tank. Maybe I just screwed up the tests. I asked...
