  • Stressor events (alk spike, pH flux, nutrient spikes, etc. ) What can we . . .
    Over the past few months I've had an alk spike (7 5 to 10 in about a month and back down in about 2 months) and a rapid rise in nutrients (n03 - non detectable to 30 ppm in about a month) at the same time This has cause some minor STN and some burnt and peeling tips
  • Pros and Cons of Alkalinity and Calcium Dosing Methods
    An overdose of the organic alk additives (e g , AFR) can drop O2 and will boost alk over the next day or so If it happens, maximize aeration Figure 7 Baking soda is a mainstay of DIY two part systems It starts as sodium bicarbonate, which can be used directly, or baked in a home oven to product sodium carbonate, which gives a higher pH boost
  • Alkalinity rising without dosing. . . possible causes? | Reef2Reef
    The rising alk got to be such a problem that I needed to do water changes with artificially lowered alk (using muriatic acid) to keep it from rising to dangerous levels So I'd do several 10% water changes with new saltwater with 5dkH over several days to slowly bring it down
  • Alkalinity controller without reagent! Aquawiz | Reef2Reef
    Monitors alk and auto doses to maintain desired alk level Reagent is 20$ that last 2 months at 6 test a day Dosing solution is cheap to make DIY with sodium bicarbonate and water 50$ add on module adds monitoring for temp, salinity and orp
  • High Alkalinity what does it really cause | Reef2Reef
    Understand that low alk can cause coral skeletons to melt and that affects the flesh on top but what happens if your alk is too high? Would assume you'd have coral growth that tissue might not be able to keep up with but how does that kill or affect corals? One other question is what really kills corals in an alk swing Thanks
  • What is Alkalinity? | Reef2Reef
    The hydroxide alkalinity (OH– – Alk), sometimes called the caustic alkalinity, is defined by some as the total alkalinity down to the carbonate equivalence point (about pH 10 7 in fresh water) Because of these potential points of confusion, in any discussion of alkalinity other than the total alkalinity, one needs to be very clear about
  • what is the most used dKH level? | Reef2Reef - REEF2REEF Saltwater and . . .
    Mainly the ALK 12 to 12 5 mixed out of the bucket Depending on water change frequency and the use of ESV Bionic 2-part it can be a juggle trying to keep things at normal range and steady I found scenarios with ALK at 12 12+ but the Calcium lingering around 360-380 being off balance after a few days
  • Alkalinity Calcium dosing and consumption | Reef2Reef
    I just spend the extra time to keep my alk stable and whatever I am dosing for alk seems to be keeping ca in balance Calcium does not fluctuate much either so perhaps your dosing more bc its not in good ratio to your alk No matter my best effort to get ca to 440 it stays around 415 -420 when my alk is 8 0-8 3 Perhaps it precipitate
  • 2 part dosing | Reef2Reef
    Ex Alk 8 0 and cal 400 and want to increase cal to 460 I believe you would add more cal dosage and maitain alk dosage to increase cal Once you reach your target numbers maintain dosage to keep the numbers where you want it I currently dose 2 5 mL twice a week for my Nuvo 20 with water weekly change to maintain my alk and cal I could also
  • Calcium too high | Reef2Reef
    I’ve been testing my tank since I started it, about 2 months ago, with api test kits and it kept coming up with Alk 7 0 and wouldn’t go down and calcium started at 460 ppm and went down by 20 ppm every 24 hours Well today I got Hanna test kits for both and tested with them It got 8 6 for Alk and 592ppm for calcium
