alk

I run a Red Sea reefer 525 xl I’m currently dosing 90ml alk (Red Sea brand) 10ml calcium( Red Sea brand) 0ml magnesium( Red Sea brand) is that’s dosing ratio typical? My target numbers are calcium 450 currently at 499 Alkalinity 9.5 currently 7.94 Magnesium 1400 currently at 1438 i can’t...

Hi all, I have a 40 g sumpless system running a canister filter. The canister is mostly filled with Matrix and has some floss for general waste capture. I’ve recently upgraded from FOWLR to starting with some corals, upgraded the lighting to a Kessill A160 blue. Current stocking is 2 clowns...

Hi everyone, I've got a kalk question. I want to eventually get a kalk stirer but it's out of my budget at the moment but I want to start dosing kalk because I dose 2 part and it's expensive, also my ph peaks at 8.1 but is not very stable so I want to get my average ph higher. Could I take some...

Hey all I have a 240g 5 months old water parameters are all good. The only issue I am having is keeping my 8.0-8.4 ph, it usually drops daily to 7.89 and hovers there. I dose alk 4 times a day at 200ml total daily. I can’t keep it to stay at above an 8. Calcium I dose 75ml a day and it...

What would cause my pH to be so high? The only thing I dose are KZ coral booster, Xtra, snow, cyano clean, vitalizer, and flatworm stop. Even the pH in my calcium reactor is high 7.9. my Alk also continually increases. The dips in the graph is when I lower it with muratic acid.

I have a well established 32 gallon tank with another 10 gallons of sump. It has been up and running for 2 years. Recently my alk has started dropping and I can't seem to get it back up. Normally I try to keep it in the 8.0 range but over the last few weeks it has continued to drop and just hit...

The alkalinity in my tank seems to be dropping steadily (about .1 dKH/day) independent of the other parameters. All parameters are tested daily because my humans are new to reefing and want to understand how everything works together. The other parameters remain relatively steady at: Temp...

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...

My alk is at 17 dKH and I was told a water change would fix this. However, after changing out about 5gal from my 20gal tank, the alk stayed the same. I’ve read in other threads that some people suggest acid, but others heavily warn against it. Is this a problem I just have to wait out?

Hi everyone, I recently installed an apex system on my tank, I have the dosing pump as well it just hasn't been installed yet. I initially set the unit up about a week ago and I got an really low alk reading initially i think the number was 5dkh. I went ahead and started doing some brightwell...

I know I ALWAYS have a little ‘test anxiety’ when performing my water tests every week (alk every other day). I always hope everything turns out well and it usually does. Problem is, when it doesn’t (or I have missed a few weeks of testing), it can sometimes bring on a little panic as the...

I made a demo video for salifert test kits. Follow the link to YouTube and comment to enter the giveaway.

Background: I have a FOWLR tank that I'm getting ready to convert into a reef tank. It's established (for about 6 years now) and I started buying the extras (lights, pumps, trident for monitoring, DOS pumps for dosing) because I know me, and I know the more automated I can get it, the more...

So my I noticed my Alk dropping just before the new year. It's typically steady in the mid 8's but my Trident was showing a pretty consistent drop. You can see in the attached pictures it went from 8.39 to 7.0 in just 3 days or so. Now I have a DOS, with Trident controlled dosing which is...

Not sure if this question has been asked before but is there a possibility I could negatively Affect my tank if I choose to dose soda ash since my tanks dkh and ph have been relatively low lately dkh 7.4 ph 7.8≈ - Hector

Hi all, It's my first post on this forum! I couldn't find the answer after looking around the forum for a while. I was looking into starting dosing AFR to maintain my alk and calcium but the instructions say to dose until you achieve 9dkh. I'm using the red sea coral pro salt which gets me...

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've been struggling to get a grip on a low alkalinity problem in both my tanks. I've got a 20g reef only tank with a few beginners corals (zoas, acans, etc.) and two SPS corals (purple birdsnest and a green pavona). They all seem fine, the birdsnest is doing well, but my pavona is starting to...

As you can see the JF Kamikazi on the bottom left is RTNing pretty fast noticed it about 3 days ago. I am going to cut it up. However, last night I noticed the monti was getting the white fuzzy almost fuzzy like spots. Is this also dying or is something eating it? I have been observing them for...

So I was speaking to my LFS earlier and they said that my alk could be rising because I have started using nopox to lower nitrates. This sounded odd but what they said kind of made sense and the time frames coinside. So my nitrates where really high at 40ppm before and my alk was at 9.1. I...

So I made a post earlier asking about new salt and I have since bought the tropic Marin salt. I was looking for salt with lower dkh as I prefer to run lower and the salt I was using was inconsistent and mixed wildly different figures each time I used it. So now I have picked my new salt I was...

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...

Hi, i have been reefing for little over a year, and have had good success with my nano low tech tank. Simple waterchanges have allowed me to grow some birdsnest SPS and montipora. I am slowly planning on doing a high tech tank, and a little larger one. I wanted to have my first sump. But here...

Hello, I have two dosers and ESV B-ionic two part. My alk is 9.5. Calcium 415. Salt 1.25 Nitrates/Phosphates at 0 (I'm trying to rise it). My acros feeling bad (bleaching). Soft skin acros feels well. I have 4 small SPS frags and two small LPS frag in the tank. Coraline algae start to grow...
