alkalinity

Just getting back in so not sure if to spend on the Hanna checkers for calc alk mag and phos or purchase something else like red sea or api or any other out there now

Just as the title says I recently started dosing Kalkwasser in my ato. 2tsp per 5 gallons. I go through about 5 gallons a week, In a 50 gallon aio peninsula waterbox mixed Reef. I'm concerned that the level may be too high? I started dosing because my ph was hovering around 7.8 and my...

So I just got a new pack of Tropic Marin classic salt. Its dKH is supposed to be 9-10 dKH, but when I mix it up it comes out to be 14 dKH!!!?!. I mixed and tossed that bag around when I first got it. Ive made two batches with the same results. I measured and used the correct salt portions: ½...

At what point in the 4 month cycle of a new saltwater tank should I start testing & adjusting the Calcium & Alkalinity? Is it best to start immediate when you initially set up the tank? Or a few months down the road when a few fish are already living in the tank & I want to introduce coral?

Hey guys I need some help I tested my alkalinity last week and it was 11 now it’s 11.58 I haven’t done anything but a water change I thought the corals are supposed to use the alkalinity why is it going up?(how do I make it go down) I haven’t used aptasia x or anything else in the tank besides...

This is the refresh of my original 3D Printed Test Kit Organizer Tray thread. The first post showcased now-old designs and one had to dig through the thread to find the new stuff, so a new thread was made to clean things up a bit as the old cannot be edited (Old thread will be deleted/closed by...

I have a 7 month old ~3g reef tank containing a faviitees, stone pipe coral, GSP, palythoa, and hydnophora + clean up crew (1 Scarlett hermit crab, 2 blue legged hermit crabs, 5 bumblebee snails and 1 tuxedo urchin). Ever since I’ve started testing calcium, my Hanna reader shows that my calcium...

Hanna HI772 Marine DKH Alkalinity Checker HC ALK Hanna Instruments HI758U Marine Calcium Checker Bought both from BRS in November 2021 and never used Looking to trade for a BRS media reactor with pump.

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...

Hi, so I’ve been using kalkwasser in my 150g mixed reef for the last five years. My alk is very low at 5.2dkh. calcium is 470 and mag is 1500. I started dosing ESV alkalinity to get the alk up. So my question - is there any reason i can’t doses ESV for alk and continue to dose kalkwasser...

alright - I'm stumped on this. Tank is 3 months old, PH is between 8.1-8.2, Salt is at 33, MG is 1240, Calcium is 480 and Alk keeps creeping from 11 into the 12's. It got as high as 14, with Ca and Mg relatively the same. If I do a 30% water change, Alk drops some, I was able to drop it from the...

Hi Guys, I understand that hobby grade test kits are used more for reference and stability. I also understand that number chasing isn't always the best to do with our reef tanks. But I would like to share a story (photos included) and get your input. For years my hanna alk checker has been...

Hi all im need to reefing and have limited knowledge and know chemistry and water parameters work but i get the gist of it. background: information about my tank. Tank Size: 45 Gallon (running for 9 months) Salt mix tropic marine pro reef salt (weekly 12% water change @ 1.025 salinity) my...

Hello, So I have a 25g JBJ Biocube. It was doing pretty good until recently. Been having issues with Phosphates and Alkalinity. So I’ve been going to the LFS weekly and having them test everything. Asking what I should do or not do. I went in yesterday expecting my Alk to have dropped and it...

Howdy! Hopefully an appropriate place to post. I've noticed over the last week or so my Alk has started to swing a fair bit from low of 8.46 to high of 9.05 with my set point 8.6 I've adjusted the dosing baseline to the average over the last month and just today increased my testing from 4/2...

I just picked up some Acropora frags from a local reefer and his alkalinity was 9.0. I just checked my current tank and I’m down to 6.8 dkh. How long is it safe to keep those frags in their bags (floating in my sump) until I raise my tank’s dkh to 9.0? Thank you.

So I’m new to the reefing chemistry but I just tested my water and these are the results I got. Are they good and what’s the level they are supposed to be at? *Syringe tips are over the results I got

My alk is off the charts high I need to reduce asap. The build is a 45 tall corner with 5 gallon fuge, ceramic reactor in sum with surface skimmer. Here's my "official" stats I recorded earlier. Can't seem to find a clear answer on lowering alk, especially using vinegar. Please please please...

I use BRS Soda Ash to control alkalinity. I mix up a gallon for reserves and keep it in the BRS plastic Mr.Chili jug with no settling. I use this premixed jug to refill a glass bottle reservoir that my DOS is fed from. The soda ash mixture in the glass bottle will settle. It’s rather...

What would cause quite a big DKH drop and a raise in magnesium? The last time I dosed was a week ago, and it was Sodium bicarbonate for the alkalinity. I tested alk 2x to make sure...same result. I'm confused and worried.

My alkalinity keeps rising and my corals are all taking a hit over the past week I am up 1 dkh I am not dosing or anything I haven’t put my hands in the tank in about 2 weeks when I last did a water change I do one this Sunday. Please help I am using salifter test kit and I have been testing...

Good evening everyone, I just tested my alkalinity with my hanna checker and the result was 11.4 DKH. I use Fritz blue box salt which mixes between 8 and 9 DKH. What could be the reason for this? Thanks :) Joey S.

Hello guys! This is my first post here. My tank is a couple years old, 300 Litre/80 gallon with a sump. I've lost some control the past year due to university and work, but now I am wanting to get back on top of it all. I lost most of my corals over the course of the year, but I still have 2...

Hi everyone, I’ve got a 2 month old 90 gallon tank that I am looking to make a reef tank, I have been stocking slowly with fish and cuc. I recently got around to purchasing alkalinity and calcium test kits and have found that my Alkalinity was at 7.9 last week and Calcium was in the 540s which I...
