Has anyone else had an issue with IO Reef Crystals having super high calc? I had a calc reading of 518 in my tank over the weekend and a fellow reefer on here suggested I mix some fresh SW and test the params, so I did and at 1.026 ppm, Reef Crystals is measuring calc at 522. Anyone else had...

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'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 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

Looking for a Hanna Checker for Calcium. If anyone has one and can ship asap, please let me know what your asking price is. If it doesn't have any reagent left, I'm not interested though. Also, if anyone has a 3 or 4 chamber reservoir for dosing that's on the cheaper side, let me know. I know...

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...

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?

Hello, I'm having a hard time to decide on the subject issue. I currently use Tropic Marin Pro-Reef salt, and my tank parameters are somewhat stable since i currently have 3 corals and a BTA, an some small fish, so my bio-load isn't heavy at all. Testing the saltmix i'm currently using, i...

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...

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!

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...

Can to high of levels of calcium, DKH, and magnesium be bad for fish or will it just precipitate out of the water?

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...

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...

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...

Hey everyone, I was curious what your favorite 2 part is? I currently use Seachems Reef Fusion 1 and 2 . What do you use and why do you like it?

Hello world! Ok so this is my situation: I have a 55g tank and a heavy stocked aquarium; because I cannot add at this moment a sump I am forced to consider all the (limited) options. I have been measuring the water quality for sometime now and I continue to have a bad problem with Nitrate and...
