alkalinity

Hi Guys, I've been testing my tank water for about a week and have recently introduced my first batch of coral - 4 small LPS frags along with a small Zoa frag into my tank this weekend. In the week leading up, I was told my Calcium was low by my LFS after I took my water in double check my...

After two long agonizing months trying to get the xepta autobalance into the United States from Spain,greece and the United Kingdom, it finally arrived yesterday, I am getting it set up now, I have not seen anyone online in the United States with one of these so I figured I would post about it...

My calcium is at 361 ppm and alk is at 8.1 dkh, these are currently the only Hannah checkers I own and don’t have a phosphate reader and I know most people don’t like API but it’s currently what I have till I can get mor checkers. Waiting for a sale but ph is a little above 8 from the color...

Hey guys I just recently got a new pectinia coral and it was doing very well the first month. I had 2 lights but now I added another light in the middle. The pectinia is located under the third one and I was woundering if that makes a difference or if they don’t like much light. 2 weeks after...

So I've been fighting with some burnt tips/STN on my SPS with the following parameters: Alk - 8.1 Calcium - 450 Phosphate - .1 Nitrate - 10 Mag - 1400 I understand that low nutrients of near 0 can cause burnt tips/STN in SPS, but I would have never thought that the levels posted above were...

My alk from the ATI ICP test has been consistently about half a point under my Hanna Checker. Hanna is showing 8.0 and typically the ATI would be 7.5. The latest test I just got the results from show it a full point under at 6.8 somehow - difference this time being it took a few extra days to...

Hey everyone, so I’m trying to stabilize my parameters and get a good dosing schedule going but my calcium keeps rising and my alk keeps dropping pretty fast. I know that they are connected and that’s why that’s happening. My alk is currently around 10 dKH and my calcium 501ppm (trident system...

So about a week ago i began dosing kalkwasser into my tank through my ATO to try to raise my alkalinity and calcium given they were both reading lower than usual. My alkalinity has increased by .2 already which is good except the kalkwasser mix seems to be making my water cloudy. I am running a...

So I just tested my alkalinity and it was 6.9 and I would like to get it back up to around 10. I want to start dosing kalkwasser through my ATO to do this but dont know if this will increase my alkalinity or just keep it stable at where it is now. Does anyone have experience using kalkwasser to...

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.
