Hi all, I'm not at the point where I want to automate my alkalinity dosing. I'd like it to be as hands off as possible. :) How is everyone liking the GHL KH Director? Thanks, lylelovett

Hey, so here are my parameter's Alkalinity 7.0 calcium - 430 magnesium - 1300 phosphate - 0 PH- 7.8-8.0 ammonia - 0 Salinity 1.025 I'm using a Hanna Alk checker for my Alk readings. This is my issue my tank isn't that loaded, mainly softies and LPS (mainly smaller frags), i have a birds nest...

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...

Hello fellow reefers, im 5 months into the hobby I’ve been testing parameters regularly but just recently after a 20 gallon water change on my 75 gallon my alkalinity went from 7.5 to 9.8 used the same salt everything the same but shortly my hammer coral, goniopora, candy cane and some zoas that...

Hey guys, According to my Seneye Reef, my pH is at 7.8 and has been dropping for a while until now, not dramatically but over a long period of time and seems to be settling at 7.8. I've been testing my alkalinity during this process and my alkalinity comes out at more often around 3 Meq/L...

Very new to the hobby. I have a 54g display + 11g sump = 65g total water. I have two baby clowns, royal gramma, lawnmower blenny, an astrea snail, and an emerald crab. Bio load is very low. Gramma, blenny and crab were just added yesterday. For corals, I have a xenia, paly and zoa-all frags so...

Checking to see what others are getting for Alkalinity results in fresh batches of Tropic Marine Pro. I just mixed 60g worth and my alk (hanna) was 6.1 dKh Although I run my DT at about 8.5 dKh....I am not terribly troubled by the NSW result of 6.1. My AWC's are small amounts of only about .4g...

Been having so many issues. I've read and read and watched videos but something isn't right. Here's my parameters followed by my issues and pictures. Any help and advice would help. Thanks in advance. MG 1440 Alk 9.8 Ca 490 Nitrate 0-5 Nitrite 0 Ammonia 0 Salinity 35 Red sea reefer max 260...

Hello! We just checked the parameters on our tank and the alkalinity is extremely high! The DKH is at 14 While looking online, my boyfriend and I seen that you can dose vinegar into your tank to lower your alk? Is this a good idea? If so, how much do I add? Pls help :) I’m still trying to...

I recently saw a huge alk spike after switching salt mixes. After contacting the manufacturer, I got a reading of 8.3dKH on multiple titrations on "clean" rodi with the salifert kit. I dont have a TDS meter on hand. I'm assuming the water must not be very clean. Membrane was changed 6 months...

So my water is staying at 11dkh (hanna) after watching the brs video on alk and coral growth I think I’m just going to leave my stable water alone instead of chasing NSW numbers how can you acclimate corals to higher dkh without shocking them ? anyone with experience greatly appreciated

Hi from the UK! I’ve just gotten into the hobby after a long time of wanting a nano tank. Everything seems to be going smoothly with salinity at 1.026 and ammonia, nitrites, nitrates being 0. One issue: my ph is stubborn at 7.6ish despite alkalinity being between 8-9 as per fritz rpm salt...

Hi all, Due to the difference in alkalinity between my tank (170ppm) and my Reef Crystals salt mix (>180ppm), I've decided to mix my saltwater a few days prior to water changes. After mixing my water for 4 days, I've noticed its alkalinity dropped faster than expected (157ppm). I think it might...

I've been searching and not finding any answer to what is the max ALK a person can dose at one given time. I have head a max raising of 1.4 dkh per day, but nothing about max at one given time or per hour. I have a 55 gallon reef and I've been dosing ALK manually (for now) trying to maintain...

Adding marine buffer has sky rocketed Dkh to near 14! I was wondering if the Dkh will drop naturally with around 10 lps corals in a 250 litre or won't there demand be high enough to make much difference?

Just finished a bottle of alkalinity reagent on my Hanna tester - alk reads 11.8. Open the new bottle and re-test to check consistency. 10.7 ... Run a third test (from new bottle), confirms 10.7! The previous bottle is still well in date, has been open for approx. 4 months. Confident my testing...

Hi all, I was wondering how much alkalinity swing over time is considered "stable". I know Alk may drift with the daily light cycle, but I'm specifically curious about variability over days or weeks. I started using a dosing pump and 2-part about 4 months ago and have been working on getting...

Hi everyone hope you’re doing well. So today I tested my water for the first time and here are my numbers Calcium: 350 Alkalinity: 7 Ph: 7.8 I have brightwell aquatics calcium, alkalinity and ph ready to be used. I’ve been doing some research on dosing but it’s hard to wrap your head around...

I've just noticed some RTN on a tort frag. I haven't had any alk swings since this frag was added and it was in a low light area of the tank Could it possibly be a pH swing? My tank size is 88gallons and I usually dose my alk "baking soda" 0.6 tsp mixed in warm rodi dosed into sump at night. My...

So I was dumb and let myself use up all the alkalinity reagent from my hanna checker before ordering more. I am currently fine tuning my daily dose so I can set up a dosing pump. All I have is an api alk test which is accurate to intervals of 1. 1 drop = 1 alk 2 = 2 alk so on and so forth...

I am looking to change out about 10 gallons in my 90 gallon reef *88 gallons=tank+fuge* housing some expensive sps frags. If my current DKH is 8.2 and the DKH of Reef Crystals is 13 would that be too much of a change? I did the math and doing a waterchange would add about .5 DKH for 10 gallons...

Hi all, I'm now using a D-D P4 Pro dosing pump and which give great control over chemical anti-interference, split dosing over a schedule etc. and its got me researching for answers to a couple of questions... For each of my Alkalinity, Calcium, Magnesium, NoPoX ... Recommended times of day to...

Hi everyone, I have a 300 gallon mixed reef system, and I am trying to make my tank a tad more stable/automated since I am traveling out of state for weeks at a time due to school. I am switching from a bubble magus dosing system (using biotech two part solution) to a korallin calcium reactor...
