calcium

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...

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...

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 -...

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...

Most hard coral (SPS & LPS) coral keepers im sure are dosing elements back into their aquarium, but how many of us ACTUALLY know what those elements really are? My newest YouTube video tries to explain more ..

I’m in LOVE with my Neptune Apex Controller, and it’s really turned me into a control freak! Which is great because my other love,besides my kids and wife, is SPS, and we all know that SPS love stability! So with the Apex, it allows me to log my parameters and see them in a very detailed way...

I just wanted topost this quick video I pre-ordered the GHL Maxi during the all the Black Friday sales. I Had my eye on a DOS for a very long time, but couldn't get over the shape of the DOS. I may be unique in that regard, but i had purchased 2 DOS units and two DDR's and sent them back. I...

As my tank is maturing so are my methods -- and I wanted to share the first of my side by side. Like many out there, I started with the reasonably priced and easily available API Test Kits and have relied on them for the first months of my tanks existence with good results to date - fish alive...

To save space in my tank stand, I am considering placing the reactor about 75 feet away from the 120 gallon display tank. It would be in the lower level of my house where I have my water mixing room. Since I plan a mixed reef that will not have a heavy SPS load, the reactor's effluent volume...

I am newer to reefing (about 6 months). I want to start trying to keep some SPS corals in my tank, Ive been successful with softies and a few LPS corals. I have a 40g IM nuvo fusion. I've been keeping track of my elements the last few weeks, and have very little swing (i'm guessing that is...

Hello all, I have had my 72 gallon bowfront mixed reef tank for around 5 years now. I lived in Boca Raton FL for the first 2.5 years and would use natural sea water from off the coast. Corals always looked great, water tests by LFS were always good on params. The only things I would ever add...

Hi folks: long story short but after Hurricane Irma I have been dosing calcium but not alkalinity. I checked my 2-part dosing with Apex immediately after the storm, and all seemed fine on the Fusion console. Unfortunately, I forgot to prime the DOS after that major loss of power, so the pump...

Hey guys, Starting to add some different corals to my tank. Currently have a hammer colony, zoa, birds nest, a candy cane, and 3 types on montipora. I got my first Hanna checker the other day. Tested the Calcium and it was at 261. I'm using Red Sea Coral Pro salt. Got me wondering what the...

I had the SRO 5000 for years before the hurricane took it out. I hear a lot of good things about Geos but the Octos have the Varios Pump. My tank is 400g display and 150g sump/fuge. Also, what feed pumps do you suggest? I thought about building an outlet on my manifold but I feel it would be...

When you start to think that you are doing the things right in this hobby, there's always a new thing that tells you that you're wrong. That's my case with KH and CA dosing. I have been dosing BRS two-part to my reef tank for about 5-6 months. Was a little hard to find the point and maintain my...
