alkalinity

Hello - I have a 5 month old 40 gal aio. Parameters below. I’ve been testing every week to 10 days and my Alk fluctuates between 6.8-6.9 DkH. All other parameters are reasonable. I do 20-15% water changes every 2 weeks using reef crystals. Mostly LPS with some ricordea and Zoas. No SPS. Looking...

Hi All, I'm in a bit of a difficult spot with Calothrix and precipitation issues and would love some help here. The system - Reefer 625 G2 set up Aug 28, 2022. 152g water volume. Water Parameters: Salinity - 1.026 Alk - 7.2-8.0 dKh (pretty stable at 7.2-7.3 dKh till I tried to raise it and...

The Triton method is quite a bit more expensive than other balling methods, but it can be run more cheaply dosing Triton Infusion together with any balling method. We could be talking big savings: with a 100G tank consuming 1dKH per day, you'd spend: 284$ per year in Triton Core7 supplements...

I’ve been at this for about a year and a half and how to handle alkalinity on my specific tank is still a bit of a mystery for me. My salt mixes at 9.8dkh - so 2 weeks ago I brought my alkalinity up to 9dkh from 8dkh using sodium bicarbonate thinking I could stabilize at 9 with my weekly 20%...

Hello, I wonder if using Balling with NaOH as the only/main source of kH increases the water's salinity by the same amount as NaCO2 or NaHCO₃. I guess @Randy Holmes-Farley will be the best to answer :)

Hi there, I just checked my parameters and my alk and calcium are both very low: Alk ~5 dKH Calc ~350 I measured both with Hanna Checker. I ordered some all-for-reef to get into dosing but can I also just add a bit more the first several days to get around 8 dKH en 450 calc? After I get to that...

Hi All, I`ve been in the hobby a while now. I have had good success with Softies and LPS but when it comes to SPS I just dont seem to be able to hit the sweet spot. Tank is a DD Reef-Pro 900 (290 Litres total system), I have a Radion XR15 (Blue) at 100% on the AB+ Setting, 10% water change every...

Hello, I would like to keep my macros on levels similar to Red Sea Coral Pro Salt (Ca 465, Mg 1390, kH 12) + raising pH to levels between 8.2-8.5 depending on the timeframe. Of course such levels significantly increase precipitation of minerals such as calcium. What can be done to prevent it...

Hey there, Following @Randy Holmes-Farley advice and BRS videos, I am keen on trying Kalkwasser as the key source of Ca, Alkalinity and pH increase. The primary reason is the fact that it is supposedly straightforward followed by lack of additional NaCl accumulation which would require...

Hey, I've noticed that common alkalinity maintaining products use either only sodium bicarb or a mix of the two. Why Sodium Carbonate is used so rear and why never alone?

My alk took a little drop over the years - my consumption is very low and the tank is sitting at 8dkh. I want to bring it up to 9dkh which is also where my salt mixes at. My thought was I was going to use Fritz sodium bicarbonate to add about 1/8th of a teaspoon a day for 4 days. 1/8 teaspoon...

Hello, First of all - thanks Randy for your contribution to spreading knowledge on this forum. Without you I wouldn't learn many things I have never heard about it, despite the fact I do not like going with the easiest and most common solution and thus I like to explore and experiment. I...

Just tested alkalinity and it’s at 14.3 should I do a water change to bring it down?

I’m trying to use the alkalinity test with the Red Sea foundation pro kit, but when doing the titration the tank sample never goes from clear to blue, and never turns green either. after a while it becomes a pale ish yellow, but never turns blue or green. I’ve done it several times now, and I’m...

I have a 200 gallon LPS only tank and was wondering if any one else experienced their tank to stop consuming alk? Before mine would consume 1 dKh daily, and the past 18 hours it hasn’t consumed any. Corals still look fluffy, no signs of algae, my dosing system is off, and I performed a 20% water...

Selling a new Alkatronic that I don't plan on using. It's brand new. $940 picked up or shipped. Paypal for payment. Message me if interested.

Hey guys. Question i normally used tropic marine Liquid buffer to maintain kh. Its a bit hard to get right, but I have tropic marine triple buffer powder and as I understand I can mix it in ro and dose it through dosing pump. Dose anyone know how much I would mix in 1 liter of water to get...

Getting out of the hobby and selling all my gear. This is a SLAVE KH Director set, it requires a P4 controller or a GHL stand-alone doser to use it. I also have my P4 controller set listed for sale separately if you need one Automated Alkalinity monitoring and control KH Director uses a...

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...

So I have my apex trident testing and I will post an image of my results for you guys. My alkalinity has been sitting at 6.28. My apex has been saying it is usually at that measurement for the last month or so, ever since I set up the trident. But I just did a test with my Hannah tester and it...

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...
