dkh

So I just bought the Hanna Alkalinity tester and just finished testing it and it is showing a reading of 7.6dKH and my pH is about 8, from the research I've done, I read that Instant Ocean usually has a high dKH of 12. My tank is relatively new but I want to start testing levels for corals as...

Hanna checkers I have left, they have all good reagents except dkh. Most only used one time. Still have plastic on the screens Nitrate HR Nitrate LR Phosphate LR Phosphate ULR (2) Dkh (2) $35 plus shipping Discount for multiples

The tank is a reefer 350, been up and running for 14 months, first corals added about 3 months ago. So recently I’ve changed salt from Red Sea blue to Red Sea coral pro(red). And just realized that the dhk of that salt is around 11.5-12. I plan on doing frequent water changes to bring my...

Hi reefers, I start using Kalk + All for reef to substitute three parts to achieve a better PH. However, I do notice my CA and MG have been raising after about a month. I have tuned the dosing volume to (my tank is 53G SPS + Euphyllia): 1050ml Kalk daily + 20ml All for Reef daily in this...

Hi, I have a Fluval evo 52L (13 gallon) 1 kenya tree frag 1 plating monti 1 gsp frag 2 small clownfish So nothing heavy at the moment, looking to get some more corals in the future I had issues with phosphate/nitrate causing huge amounts of green algae that I now have under control by using...

Can dosing alk drop PO4? Is it appropriate to assume I made the corals happy and they are using the PO4? Both are being measured with Hanna testers that have always matched up with ICP tests. I started dosing Red Sea KH/Alkalinity to bring my system up to proper levels. I was in the 5’s and...

So, here is my dilemma. I have been testing my tank religiously with the Hanna DKH Checker for the last 2 years. I do not currently use a Salifert or any other brand DKH checker to validate the test results of the Hanna checker. I have prepared three 5 gallon buckets of salt water for a 15...

So I’ve measured my KH with two different API KH tests and they were quite different from each other. I would’ve accepted one or two DKH difference but it was a difference of 6… one measured 10 and the other measured 16. Anybody else have experience with this? I know I’ve heard people say API...

Hi, Today did some testing and I found that my alkalinity is pretty low. dKH: ~6 Ca: 470 Mg: 1440 Salinity: 1.025 pH: ~8 Nitrate: ~6 Ammonia and nitrite: 0 These testing results are 1 week after a water change. I use Tropic Marin Pro salt and a new batch of water has around 7,2 dKH. Should I...

I currently use Red Sea Coral Pro salt which has a dkh of 11.5. I started using All For Reef on my 25 gallon mixed reef tank which I'm assuming has a dkh around 7.5 ~ 8.5. Is it worth the cost of raising the dkh of the All For Reef by addition of alkalinity? Or should I start using Red Sea's...

Heyo, ** Questions: - from what I'd read if I were to dose some of the calcium carbonate part of my b ionic solution it - seemed like I could precipitate out some phos into crystals, out of water column, but being that I don't have a skimmer I don't think this would be beneficial to export it...

I'm new to saltwater but have been a freshwater hobbyist for awhile now. My SW aquarium is up and cycled. It currently stocks around 15 hermits and 1 Molly along with several different corals. I am using IO reef Crystal's for a salt mix. The first post cycle water change was done 6/29 but I...

So I have an issue that i can't seem to find a solution to online anywhere. Over the past few weeks my alk has slowly been rising. I run my mixed reef normally at 9 dkh but over the past weeks it has slowly been creeping up, currently 9.6 confined by a Hannah checkers and a salifert test. I am...

Adding marine buffer has sky rocketed Dkh to near 14! I was wondering if the Dkh will drop naturally with around 10 lps corals in a 250 litre or won't there demand be high enough to make much difference?

Hi all, I was wondering how much alkalinity swing over time is considered "stable". I know Alk may drift with the daily light cycle, but I'm specifically curious about variability over days or weeks. I started using a dosing pump and 2-part about 4 months ago and have been working on getting...

I am looking to change out about 10 gallons in my 90 gallon reef *88 gallons=tank+fuge* housing some expensive sps frags. If my current DKH is 8.2 and the DKH of Reef Crystals is 13 would that be too much of a change? I did the math and doing a waterchange would add about .5 DKH for 10 gallons...

I just got test kits for these two things and it says my calcium is 340 and kh is 17.9ppm or 1dkh with api test kits. What should I do to get these levels up??? I also don’t understand the difference between all, dkh, and kh.

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...

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

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...

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?

I read an article a couple months ago saying that Automatic Alkalinity Monitoring and Control Coming to Apex Edit: use link from post number 3 Has anyone heard any updates from Neptune about this? And I haven't read if this will be for dosing only or if it can be used with calcium reactors as...

Hi all, We updated the reagent product code used for the HI772 dKH Alkalinity Checker. The new code is: HI772-26 Marine Alkalinity Checker® HC Reagents for HI772 (25 Tests) http://hannainst.com/marine-alkalinity-checkerr-hc-reagents-25-tests.html This have been updated from the HI755-26...

I have been researching Alkalinity levels in SPS dominant reef tanks and the numbers are all over the place. So I decided to poll R2R members and see where you like to keep your Alkalinity in your Reef tanks. Feel free to comment on what type of tank, salt, and method of Alkalinity...
