Hi there, let me introduce myself to this new world I'm entering.
This is my first saltwater tank that someone I know started on May 15, 2025, but unfortunately, he has no time to continue with the hobby, so he searched for someone who wanted to take over, and I did! I know it isn't easy if you're new to this world, but I did a lot of research to start well.
For now, I'm testing daily, and we had some issues with transporting the water. There was one Jerrycan with a leak, so I had to make some new water. But now my calcium and magnesium are a little bit high.
13 months, 75g, calcium consumption way up. Growth increase.
13 months, calcium consumption way up last 30 days. 125g
Hi. I have an issue with high calcium in my nano tank. Do you have any suggestions or recommendations on how to reduce it? Or should I just leave it alone?
How much score do u guys give for my reef tank in a 100 score?
Equipment:
BOYU WG-310 (impeller modified for better airflow) (protein skimmer)
Aquael FZN PRO 700
Yee submersible pump (1000L/H) (used as wave maker)
18w reef light + 5.2w yikeda reef light
Some random desk fan modified as cooler
2in1 thermometer+salinity meter
Fish and coral inside:
Favia
Mushroom
Damselfish
Ocellaris clownfish ×2
Thickness of the sand
1~5cm
Salt used: Vastocean basic ocean sea salt
Salt parameter:
CA~ 400-450MG/L
MG~ 1250-1350MG/L
KH~ 7-9 d°KH
(The rest.. Idk)
So, I finally broke down and bought some Hanna Checkers, I've been in and out of the hobby since the late 80s and have always relied on titration tests but with my latest system I have not been able to nail down my parameters, I tested one number and my LFS with my own test kit tested a wildly different number. I know these test kits vary wildly from manufacturer to manufacturer and from user to user but my own back to back tests were all over the place. I know Hanna tests have variations but for me and my old ass eyes it's much easier to read a digital number display than try to distinguish between shades of pink, blue and green.
Little high on calcium but I think the Hanna is off some
So I tested parameters today. All looks okay. Nitrates are a little high but nothing concerning (I wouldn’t think). The only thing I see is calcium being pretty high. Anyone have any ideas why I might’ve had the cyano outbreak? I’m trying to make sure once the lights come back on that it doesn’t come back swinging, but I can’t seem to find the root of it. It could just be me not looking in the right place, but hence the questioning.
The atoll grows. Had an eel escape to the sump and stir up the mulm. Been vacuuming the sump over two weeks. Finally caught the eel. The escape took my levels from 20 no3 and .2 po4 to 50 no3 and 1-.5 po4. Mag dropped to 1100. Had to dose 1800 ml mag to bring it back to 1365. Phosguard to reduce po4 from there to .50-.25. Added white vinegar to kalk for bacteria and take no3 to covert it into more of a meal for coral and clams. Somehow the cal dropped from 420 to 390 over night after the phosguard kicked in. Likely coralline growth but clams and sps could also be culprits as po4 inhibition levels are reduced. Making a batch of calcium chloride to dose over 2 days and bring it back up. Only use chemistry and nature here.
Hi everyone.. it's Sunday. water change day. besides cleaning the tank. I added a few corals. I have a new Arrow crab. and started to add Kalkwasser again. it's been 2 weeks and my calcium levels have been reading 390. that's why some of my corals look closed. I'll get that fixed. happy reefing. Thanks for watching. 🙂
Made some routine changes… started dosing All For Reef and adding Coral aminos daily… finally got the alkalinity stabilizing and calcium to come down to normal ranges. Mt first two corals, the favia and trumpet, I thought I was losing during these fluctuations. They’re popping and coming back, and the trumpets are starting to fill out again! Finally on the right track. Going to get a single dosing pump to help with the consistency.

Anyone have some tips to maintain calcium? I’m having some trouble with it averaging between 399 and 540…other levels have been good. I was dosing weekly Nano part A and B, but quit to kind of monitor things and didn’t see much of a change. I’m great with my water changes, do 15-20% every weekend.
