    High alk and nutrients

    So i recently had a major issue with my euphylllia Coral. It had nearly died completely. When i tested my water i was at nearly 12 dkh. With nearly 0ppm phosphate and nitrate. I started dosing coral Amino and polyp booster daily along with my regular feeding. Now about 2 weeks later the coral...

    Dosing more Alkalinity than CA

    What effect will that have on my tank? I have noticed white specs all over my glass seems like precipitants. I know they are not alive I simply clean my glass and a few weeks later they return. Is this from mostly dosing Alk? If I continue this what will happen? So I am very new at Reefing...

    The Ways Alkalinity can Accumulate in a Reef Tank

    The Ways Alkalinity can Accumulate in a Reef Tank @Miami Reef "Why is my alkalinity rising?" is a seemingly simple question that consistently pops up in the chemistry section of Reef2Reef. However, it is a complex question since there are numerous ways alkalinity can accumulate - some ways one...

    PH and ALK Questions

    Good afternoon, I have been having some trouble with alkalinity and PH lately. My alkalinity has been going down lately. The lowest I’ve seen it was 6.6(DKH) so I do a water change to bring it back to 7 (DKH) which I’m comfortable with. However I’d like to be in the 8(DKH) range. Also looking...

    How to to raise calcium without affecting alkalinity?

    So for a few weeks now my calcium has tested at 280-310 which I obviously would like to get up to closer to the 400-450 range. The only thing is my alkalinity has been fine at a steady 8.2. Is there a good way I can raise my calcium without it affecting my alkalinity?

    Alk dosing

    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...

    Advice Needed - Newer tank, Cyano, Low alk, and precipiation issues

    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...

    Adding the Triton method to any balling method with Triton Infusion

    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...

    Help me figure out what to do about my alkalinity

    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%...

    NaOH vs NaCO2 in Balling - which raises salinity more?

    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 :)

    Raise alk and calcium with all for reef

    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...

    Alkalinity (and other parameters) - When is a swing not a swing?

    Avoiding precipitation with high macro minerals levels

    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...

    Kalkwasser as the main source of macro? Is anybody using 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...

    Why Sodium Carbonate is not using alone but usually with Sodium Bicarbonate?

    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?

    Corrective Alkalinity dosing help

    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...

    Red Sea alk test never turning blue.

    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.

    Talk alkalinity stagnant

    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...
