    Hey guys! Trying to catch a problem before it gets out of hand but not sure this is a problem or not. Last month I added quite a bit of mixed livestock and have noticed since then PH has been through the roof (8.4 and going up daily) and I cannot seem to dose enough Alk to keep up with the...

    How can my alk be this high?

    I've set up a tank, which at the moment only has a couple of clowns and cheato luckily. It's a barebottom with Aquaforest rock. Since it's a new tank with no corals, I've not checked Alk often, only NO3 and PO4. I use RO/DI, which I check regularly, and my instant ocean mixes to 11 dKH, but, I...

    Started Moonshiner's dosing, alkalinity spiked in Trident testing

    I have a mixed reef Waterbox 275 and just started using Moonshiner's dosing. After an ICP test I added correction trace elements including boron and my Trident reading for alkalinity jumped from 7.89 to 13.4. I though I would have a heart attack and tested with Sailifert and the alkalinity was...

Ph is also always around 7.8 I doesn’t have an auto doser yet but I’ve tried dumping doses of kalkwasser and sodium bicarbonate from brs without much luck. I only have about 5 little zoa frags so I’m...

    pH and Alkalinity Consumption

    Hello all! I'm curious about the relationship between pH and alkalinity consumption in my tank. I understand that a higher pH promotes faster growth as well as both biotic and abiotic precipitation, but I'm wondering how much of an increase in alkalinity consumption I should expect when...

    Newbie Alkalinity Question

    Hey there, new reef keeper here. I had a question about alkalinity and pH. My pH was 7.9 and dKH 8.0. I wanted to raise both so I added 20mL RedSea foundation B to my 25g tank. The pH went up to about 8.6 and dKH 10.2. But after 2 days the pH has dropped to 8.0 and dKH to 9.0. I have no...

    Raising alk without PH

    So I've noticed over time my ph is increasing with dosing for alk (wasser). The past couple months I've seen it go from pH 8.15-8.25 on a given day to 8.3-8.4, alk at 8.0. I'd like to increase my alk but I'm worried about driving my ph too high. Anyone else see this? How to fix?

    Dosing more Alkalinity than CA

    What effect will that have on my tank? I have noticed white specs all over my glass seems like precipitants. I know they are not alive I simply clean my glass and a few weeks later they return. Is this from mostly dosing Alk? If I continue this what will happen? So I am very new at Reefing...

    PH and ALK Questions

    Good afternoon, I have been having some trouble with alkalinity and PH lately. My alkalinity has been going down lately. The lowest I’ve seen it was 6.6(DKH) so I do a water change to bring it back to 7 (DKH) which I’m comfortable with. However I’d like to be in the 8(DKH) range. Also looking...

    How to to raise calcium without affecting alkalinity?

    So for a few weeks now my calcium has tested at 280-310 which I obviously would like to get up to closer to the 400-450 range. The only thing is my alkalinity has been fine at a steady 8.2. Is there a good way I can raise my calcium without it affecting my alkalinity?
