    EMERGENCY Help! Water parameters are getting me frustrated…

    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...

    Trident/DOS dosing and Alk swings

    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...

    New Frags - How Long Will They Last in Plastic Bags?

    I just picked up some Acropora frags from a local reefer and his alkalinity was 9.0. I just checked my current tank and I’m down to 6.8 dkh. How long is it safe to keep those frags in their bags (floating in my sump) until I raise my tank’s dkh to 9.0? Thank you.

    KH, CA, Mg Result Questions

    So I’m new to the reefing chemistry but I just tested my water and these are the results I got. Are they good and what’s the level they are supposed to be at? *Syringe tips are over the results I got

    BRS Soda Ash Settling in Dosing Reservoir

    I use BRS Soda Ash to control alkalinity. I mix up a gallon for reserves and keep it in the BRS plastic Mr.Chili jug with no settling. I use this premixed jug to refill a glass bottle reservoir that my DOS is fed from. The soda ash mixture in the glass bottle will settle. It’s rather...

    Alk and magnesium being weird.

    What would cause quite a big DKH drop and a raise in magnesium? The last time I dosed was a week ago, and it was Sodium bicarbonate for the alkalinity. I tested alk 2x to make sure...same result. I'm confused and worried.

    Reason For High Alk

    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...

    Confusing results when figuring out "4 day dosage" of Foundational elements!

    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...

    Kalkwasser stirrer: How to make it drip evenly?

    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...

    Non DIY Sodium Carbonate 2-Part Product in the UK?

    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...

    Alkalinity too high

    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?

    Alk & Cal Stability

    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.

    Sodium and Chloride imbalance

    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...

    Which Alk/Ca values should I believe?

    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'...

    Normal Alk Consumption? Reefer 170 with mostly LPS + Clam

    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...

    How Fast Can an Acro Uptake Elements?

    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...

    Daily Alk/Ca consumption off

    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...

    Is it Normal for no ALK/Cal Use in a Week?

    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...
