  • Killed a hammer by dosing Alk the wrong way. . . | Reef2Reef
    I had an unstable tank as my couple LPS (2 hammers, one with 2 heads, another with 4 heads), coraline algae and couple SPS ( montipora and leptoseris small frags) were starting to demand Alk and calcium ,and magnesium, and I was dosing irregularly every 2 3 days manually, then I decided I needed automated dosing, so acquired a dosing pump
  • 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
  • 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
  • alk, mg and ca levels | Reef2Reef
    this is a 60 g tank 1 skimmer hob eshopps 60 lbs of live rock live sand for substrate 2 wave makers and 2 heaters little concerned about my levels for alk mg and ca alk - 420 mg - 1200 ca - 420 po 2 ph - 7 4 nitrites 0 nitrates 10 recommendations? I am using crystal reef by instant ocean
  • 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
  • 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
  • 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
  • Ideal Alkalinity for SPS growth? | Page 2 | Reef2Reef
    I know that if my Alk is lower than about 7 5, my pH will drop below 7 65 If pH higher than 8 in the summer and 8 2 in the winter, alk is above 9 I never chase pH The main factors in controlling pH are alk level and dissolved CO2 I can’t control CO2 well in a house full of people so I accept lower pH and keep alk STABLE My corals don’t
