Hi all, I have been having issues with my pH on my 29gal reef tank. For some reason it always stays around 7.7, no matter what I do. On a 20% water change, it goes up to 8.0+ which should be perfect. After 3 days it drops again at 7.7. My kH is around 12, so I cannot add buffers anymore (I used...

Hi all, question about additives. My 220g ph is 8 and alk is 1.36meq/L (dkh 3.8) My calcium is 440 and mag is 1440 I just added reef buffer to increase ph and alk when I did the 25% h20 change but Im wondering is it necessary to add it too my 13gallon top off tank as well, or just adding it to...

back story. I have been fighting low pH bottoming out at 7.6-7.5. At this point I am confident that it is due to high levels of CO2 in my room or within the tank cabinet because if I open a window or the cabinet doors the pH rises. I know it is an easy test to verify but I have been a little...

something new every day I finally broke down and a reef master test kit- thanks amazon :) after the run around of changing things in the tank here are my new parameters Salinity 1.28 PH: 7.6 Calcium 500+ KH - off the chart- based on the chart dkh is 14 making it 250.6 ppm ammonia : 0...

So i bought a used 60 gallon tank with 4 fish and a few corals and added a few more corals on my own. after my first full week without a water change and here are my numbers pH 7.8 Calcium 360 12 deg DKH Phosphate .25 ammonia 0 nitrite 0 nitrate 10 I am thinking of adding kalkwash to raise my...

What can I do to keep my pH up? Using eight-four and it goes back down the next day It stays between 7.8-8.0

My 40 gal breeder has been up and running now for about 5 weeks You can see my posts under new 40 gal breeder Initial pH was 8.2, but noting this week pH has fallen to 7.8 Checked with test kit as well as calibrated meter I already am growing chaeto, and its growing like crazy, so dont think...

Well my new tank is 6 days old! Shrimp is rotting and cycle has started and life is good! Ran some tests today and all was good save my ph. It's 7.62Checked my other tank and got 7.77. Knowing that lighting plays a role in ph I turned the lights on for a couple hours and saw 7.79. I know the...

Hey all... I've always struggled with low pH in my tank (40B w/ 10g sump). We live in a cold winter part of Oregon, and have the wood stove going all winter. The tank is in the living room, same as the stove. I did the aeration test... Tank pH before and after aeration inside the house...

29g biocube, been established years. Never had a problem with any water tests other than small nitrates once in awhile.....ph is down to about 8.0 or maybe even 7.9 or so. I've missed the last 3 weeks of water changes and last week my Coral beauty died outta nowhere when we had a temp spike from...

Okay so my reefing buddy has a fun toy he built years ago, honestly it seems a bit weird but does make some sense. Basically its improving O2 levels being pulled into a skimmer or via airstone. As opposed to stripping Co2 (which is sort does anyway) He built a enclosed terrarium of sorts...

My pH used to always be around 8.2, so of course I stopped testing it, assuming it was fine :rolleyes:. I decided to test a bunch of stuff today, just for the fun of it, and found the pH was 7.8 or 8.0 (these test kit colors make it hard to read - API test kit). It was about 5 hours after lights...

have been looking around for a week or so and cant find anything that works well. issue is my ph is low and always has been, but lately its been very low, 7.5ish low, the refugium is set to a opposite light cycle than the main tank. ive tried baking soda, opening windows, raising the Alk a...

I'm struggling to bring my pH up to 8.4. I've been dosing with 8.4 and it has helped some but it seems to be staying at about 8.0 and not going up from there. Is there something else I can do? Is it just due to being a young tank?

Hi all, Yesterday I setup my calcium reactor and after 24 hours, my calcium reading appears pretty perfect at 460 and my dkh is at 10.9. This morning when i turned my lights on, my tank ph is very low though at 7.63. (It is now at 7.74 a couple hours later). I need to know what I should do at...

Hi, I am a new member and I am also quite new of reef tank keeping (I have been running a few FW tanks and still have one). After reading many of the great posts and comments on this and other forums here on The Reef Tank, here I am with my first question hoping in some suggestion/comments from...

Good Morning All, I have been having a problem with my zoas slowly closing and diminishing in number for the last few weeks, but it was a slow process until a few days ago when I decided to take a closer look at them. I found a snail I didn't recognize, some waxy stuff coming off the outsides...

Hi. In new to this forum. My 200 ltr reef tank ph is 7.81 and kh 19. How do i get the kh down and increase ph to 8-8.2. Tried doing simple water change. Then the ph drops. If i add buffer, the kh shoots up. Using tmc pro reef salt and ro water. Also my kh stays between 17-19 but ph droop...
