    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...

    Does potassium nitrate and potassium phosphate react?

    I currently dose 1mg kno3 and 0.04mg kpho3 weekly but since it's weekly i often forget to do it, sometimes a couple weeks in a row with visible degradation to acro health, so i want to automatically dose it. I only have one channel free on my kamoer dosing pump. Can i mix potassium nitrate and...

    Calcium and ALK levels - are mine ok?

    I’ve been in the reef game for a long time, but took a break for a while and just recently got started again. This time around I’m trying to make sure I really stay on top of water parameters, so I’ve been testing regularly. I started this time with a used tank from my dad, a Red Sea 350 and re...

    Add phosphate with doser then remove it with gfo reactor on timer?

    Is it possible to dose phosphate during the optimal period of the daily photo cycle, based on the best time corals are known to absorb phosphate from the water? Then to keep it from climbing, and reduce the time spent monitoring, remove the phosphate daily, with a GFO reactor on a timer, running...

    NO3 and PO4 chemistry

    I have a question about NO3 and PO4 chemistry. Usually when PO4 drops NO3 would drop with it right? I've been having problems keeping PO4 up, so far I removed pellet reactor and disconnected the refugium. But as soon as I turn the fuge back on the PO4 drops too fast, is it possible that the...

    Is Anyone's Hanna Magnesium Checker Not Reading High?

    I've heard about the problem of Hanna's Magnesium colorimeter reading high and recently learned that you can fill out a form on the Hanna website to get them to send out a new Reagent to correct the issue. But has anyone not had to do this and is getting similar results to other tests they do? I...

    Why are magnets bad for reef chemistry ?

    Why are magnets bad for the reef tank? I have read many threads where individuals blame magnets for all kinds of misery. I am getting ready to make some magnetic accessories for my tank but I want to be prepared for my consequences if I fail to adequately protect them from poisoning my tank...

    dKH pretty low, calcium and magnesium normal

    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...

    Dino-X and Neonitro

    Hey guys once again battling algae… started dinox last night and it says not to add trace elements and no products that absorb. My tank is ultra low nutrient and I want to add Neonitro to help battle the Dino’s. Can I do both at the same time?

    Dosing iodine to freshwater and testing with Hannah iodine checker. Possible?

    So I accidentally bought the Hannah iodine tester for freshwater and have been wondering how I could safely dose to the reef tank without an ICP test. I was thinking I could add iodine to an ATO or mix it in my freshwater and then test prior to adding salt to achieve .06 iodine levels. I'm not...

    Nitrates & Phosphates

    Happy Holidays Fellow Reefers, Here’s the skinny… I have a Coral/Invert QT with a few frags in it, nothing flashy, couple of smallish rocks, frags, and some snails. Nitrate & Phosphate are consistently reading 0, everything seems happy, save a temperamental Kenya, but otherwise good. My...

    Got my ATI results back and need help with a game plan.

    I just got my results back. I took my sample the same week that I started a chaeto reactor so know my nitrates and phosphates will come down, but am concerned that my nitrates are 135x my phosphates instead of about 10x like I see being ideal. I’m thinking of starting to dose NoPox but am unsure...

    Alk creeping with auto water changes

    alright - I'm stumped on this. Tank is 3 months old, PH is between 8.1-8.2, Salt is at 33, MG is 1240, Calcium is 480 and Alk keeps creeping from 11 into the 12's. It got as high as 14, with Ca and Mg relatively the same. If I do a 30% water change, Alk drops some, I was able to drop it from the...

    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...

    Adding a few gallons of ocean water to my tank?

    Hi all, So I'm thought I might grab a few gallons of Pacific Ocean water to add to my tank over time. I have a 150g tank using Instant Ocean reef crystals. The water won't be taken near a marina or any known pollutant type areas. Has anyone had experience supplementing their tank in this...

    Skinny Xenia and iodine

    Hello, I got a pulsing Xenia about 4 ish months ago, and up until the last month and a half it was doing well and pulsing like crazy. Now the polyps are skinny and not as puffed up without any pulsing whatsoever. I have also been battling prorocentrum dinos and now have a forest of GHA however...

    Stabilizing PH and ALK

    Since I’ve added some Zoa frags to my tank, I’ve had wild swings in dKh and PH in my Fluval 13.5G tank. I know with a small tank, this can occur, but any advice on how to stabilize this? No ammonia or nitrite Nitrate is between 5-10 ppm No detectable phosphates (only have API kit so might not...

    WIll the clownfish be ok? help

    Heres what happened, Im fighting dinos, specifically procentrum, and I started dosing silicates. I used sponge excel, and dosed 5 drops into 10 gallons. The drops did harden upon contact with the water and turn into white flakes. I know that silicate based solutions are caustic to humans, but...

    Nitrate 10ppm after water change.

    Really confused about a couple things. First I did a water change in my 45 gallon tank after I notice I have no nitrite ammonia Is .25ppm which I read means 0 since it’s an ati test kit. My issue is the nitrate is light orange so in between 10-20ppm. Second day I checked and still hasn’t really...

    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.

    Looking for a reef chemist here

    I'm just curious about sea salt. I'd like to know more in depth of why it's not good to use sea salt that has moisture in it to use it in a fish tank. I'm a little confused because it gets wet/ dissolved into our aquariums and I'm pretty sure alot of salt on the market comes right out of a wet...

    Problem raising magnesium.

    I can't seem to raise magnesium, I am worried that if I put anymore in that maybe the levels will come up overnight for some reason? Pls help not sure if I am wasting my 2 part magnesium mix. My levels at the start of the day was 1140 magnesium, it is now at 1185. Can't seem to get it to 1200.
