alkalinity

Good evening everyone, I just tested my alkalinity with my hanna checker and the result was 11.4 DKH. I use Fritz blue box salt which mixes between 8 and 9 DKH. What could be the reason for this? Thanks :) Joey S.

Hello guys! This is my first post here. My tank is a couple years old, 300 Litre/80 gallon with a sump. I've lost some control the past year due to university and work, but now I am wanting to get back on top of it all. I lost most of my corals over the course of the year, but I still have 2...

Hi everyone, I’ve got a 2 month old 90 gallon tank that I am looking to make a reef tank, I have been stocking slowly with fish and cuc. I recently got around to purchasing alkalinity and calcium test kits and have found that my Alkalinity was at 7.9 last week and Calcium was in the 540s which I...

Hey guys I recently started using kalk I’ve had kalk+2 for the last few years but never actually used it before till last week the goal was to stop my 2 part dosing at night and add the kalk to keep my ph higher at night then again my high is usually 8.4-8.5 and low is usually 8.1-8.2 so i wont...

Hello all! I have a 13.5 fluval evo, recently I've been trying to figure out the daily dosage for calcium, magnesium and Alk. Unfortunately right now when I measured my prams i got very confusing results and i need help! My salinity is at 35 ppt measured by a refractometer and held stable by...

I have a Deltec Kalkwasser stirrer, and frankly the design is pretty much the same as most Kalkwasser stirrers out there. I feed it with a dosing pump, about 200 ml per hour. The problem is that the water level rises inside the Kalkwasser reservoir and suddenly squirts out several ml at the...

Hi folks, I am looking to implement 2-part/balling method using sodium carbonate, however most products I see being sold here in the UK use sodium bicarbonate. I would like to run my pH a little higher, hence my interest in using soda ash. BRS soda ash is not available here, and although I am...

So I'm not sure how i would to put this all together but here goes I'm wondering if i should dose, what i should dose and if I'm just crazy.. I've done some research and i still just cant decide. My tank stays around these parameters As of last night 3/14 and about an hour before lights off...

My tank has been cycling 2 weeks now and my alkalinity is at 14! Is this normal at this early stage? Will it sort itself out?

Hey all quick question, If alkalinity and calcium (but more importantly alk) is not stable and maintained properly, will that stop or slow down coral growth? Even including soft corals even though they don’t rely on those elements as much as stony’s? Thanks as always everyone, happy reefing.

I started a new tank recently and waited 8 months to hook up my trident because I didn’t see a reason to waste reagent without much in the tank. I use HW-Marinemix Reefer which according to BRS tested at 9 dKH, 450 Calcium, 1380 Magnesium. I used the reef calculator to find out how much Sodium...

I have a New Years resolution to keep my tank chemistry as stable as possible to allow my corals to thrive. They are doing fine now with good growth and color and want to keep it that way. However, depending on the test kit I use I'm getting different results so not sure exactly what the 'now'...

Photo and tank parameters below. Started dosing about a month ago due to getting a Squamosa Clam, its currently about 4 inches. Tank is mostly LPS with a couple of montiporas. I'm continuously having to increase my two-part dosing. I'm currently dosing Alk + Calc ESV at 6ml a day. 1ml x 6 doses...

I am new to the reefing hobby, and I just set up my first Mr. Aqua 12g Long aquarium. After the cycle was finished, I threw in a few test zoas, and they did fine, so when I saw a large frag of an acro labeled "garf bonsai" at an LFS for a good price, I couldn't resist buying it. I didn't have...

Been monitoring my 9 month old nano tank (35 total gallons) and it consumed roughly 20 ppm Ca and 0.3 dKh per day. Using the reef calculator that would be 20.2 ml Bionic Alk and 43.7 ml Bionic Ca : nearly 2 to 1. I'm using Hanna testkits right now to measure Ca and Alk. Does that sound weird...

So I have a year old 45g cube with some LPS and softies. Total maybe 20-25 corals. It's not overly stocked, so maybe this is pretty normal, but I feel there would be some use in my alkalinity or calcium levels. I checked over a week and looks like no use of any alk or calcium. Check Alk with...

My Waterbox 130.4 is 8 months old. Marco Rock, refugium with chaeto (running light overnight), BRS GFO in reactor, protein skimmer, floss, and bag of BRS carbon. Parameters (see below) have all been very stable with minimal coralline taking hold. Weekly 10-15% water changes with Marin Pro...

Hi everyone, hope you and your reefs are all doing well. I just wanted to discuss something quick. I’ve read a lot of forums about how doing a 10% water change weekly/bi weekly or a 20% water change monthly is enough to replenish the elements for a softie only tank since they don’t consume a...

So... I had a tank 'almost crash' about 6 months ago. I was preparing for a new tank, moving around stuff on my EB832s, rewiring sensors, shuffling my gear, etc. My C02 feed for my calcium reactor went offline... I noticed but was busy with other stuff and thought it could wait a few days. A...

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...
