calcium

Testing with Salifert and API respectively, my magnesium is 1530 and calcium is 360. Is this normal? Should I dose calcium? If so, how much? My tank is 20 gallons. Also got a male and female cleaner shrimp recently. The female died this morning, wondering if the clowns pestered her too much or...

Hello all! I have a 13.5 fluval evo, recently I've been trying to figure out the daily dosage for calcium, magnesium and Alk. Unfortunately right now when I measured my prams i got very confusing results and i need help! My salinity is at 35 ppt measured by a refractometer and held stable by...

How does one go about lowering your alkalinity and calcium? I followed directions from brs calculator on adding a 2 part to my tank. DkH was 13.5 and calcium was 423. It said to add 13.7 ounces. I thought that was a lot and only added 4 ounces. This morning DkH is 13.3 and calcium is 523 Tank...

For the last several weeks, my Hanna checker has shown my tank to have roughly 500ppm calcium. I was alarmed by this because I don't dose calcium and have no idea where the extra calcium could come from. I decided to test my water mix (Instant Ocean at 1.024 specific gravity) with an ICP and...

Hey all, I would like to ask your support here. I have a 100 gal system for 50 days. Cycling complete: Nh4 0 Nh3 0.001 Nitrite 0 Nitrate 8 ppm Phosphate 0.07 ppm Ph was 8.27 about one week ago with a co2 scrubber. But after following very closely the indicators above I tested the following...

Hey all I need an advice here. I have a refugium with a chaeto set about 15 days ago. It was fine until yesterday when started to break in a few pieces. Today in the morning it was worse, so I took out from the sump because started to spread a lot of pieces in the tank. It is still green...

Hey all quick question, If alkalinity and calcium (but more importantly alk) is not stable and maintained properly, will that stop or slow down coral growth? Even including soft corals even though they don’t rely on those elements as much as stony’s? Thanks as always everyone, happy reefing.

Hello, I have recently started a 180 build that was cycled in September 2020. Tank is doing great, however, my calcium stays high and I do not understand why or what I need to do different. I don’t even dose calcium but it stays 520-550. Any advice would be much appreciated!

I have a New Years resolution to keep my tank chemistry as stable as possible to allow my corals to thrive. They are doing fine now with good growth and color and want to keep it that way. However, depending on the test kit I use I'm getting different results so not sure exactly what the 'now'...

Been monitoring my 9 month old nano tank (35 total gallons) and it consumed roughly 20 ppm Ca and 0.3 dKh per day. Using the reef calculator that would be 20.2 ml Bionic Alk and 43.7 ml Bionic Ca : nearly 2 to 1. I'm using Hanna testkits right now to measure Ca and Alk. Does that sound weird...

So I have a year old 45g cube with some LPS and softies. Total maybe 20-25 corals. It's not overly stocked, so maybe this is pretty normal, but I feel there would be some use in my alkalinity or calcium levels. I checked over a week and looks like no use of any alk or calcium. Check Alk with...

Hi everyone, hope you and your reefs are all doing well. I just wanted to discuss something quick. I’ve read a lot of forums about how doing a 10% water change weekly/bi weekly or a 20% water change monthly is enough to replenish the elements for a softie only tank since they don’t consume a...

Very new to the hobby. I have a 54g display + 11g sump = 65g total water. I have two baby clowns, royal gramma, lawnmower blenny, an astrea snail, and an emerald crab. Bio load is very low. Gramma, blenny and crab were just added yesterday. For corals, I have a xenia, paly and zoa-all frags so...

I have an AquaMaxx cTech T-NANO hang-on calcium reactor. I just set it up on my 11-gallon aquarium because I recently got my first stony coral frags and want to start maintaining proper chemistry for these corals. I’m using a Versa peristaltic dosing pump from EcoTech Marine to dose the...

Hi, i have been reefing for little over a year, and have had good success with my nano low tech tank. Simple waterchanges have allowed me to grow some birdsnest SPS and montipora. I am slowly planning on doing a high tech tank, and a little larger one. I wanted to have my first sump. But here...

Hello guys! I have been trying to dial in my tank to stick to kalkwasser only. I accidentally dosed a bit too much calcium about 2 weeks ago which spiked my cal to 597... I been waiting out which has brought it down to 592 but I’m concerned it’s lowering too slow and will cause harm to my...

So I've just tested my Calcium with Hanna twice now and it's telling me a reading of 520... I was wondering if this could be why my tank water looks cloudy and my mushroom isn't as happy as he normally looks.

Hello, I have two dosers and ESV B-ionic two part. My alk is 9.5. Calcium 415. Salt 1.25 Nitrates/Phosphates at 0 (I'm trying to rise it). My acros feeling bad (bleaching). Soft skin acros feels well. I have 4 small SPS frags and two small LPS frag in the tank. Coraline algae start to grow...

I have a spare Hannah Calcium tester I’m looking to trade for a Hannah Nitrate tester. If you have one to trade or sell; hit me up. Thanks.

Good afternoon and thank you in advance for helping me. I have a relatively new tank (been up for about 8 mos), fairly well stocked mixed reef. Red Sea reefer 525 XL. Until recently i have not had to dose. Continuous water changes were maintaining my ca/alk/mg levels pretty well. When I started...

Hello everyone, I have had my tank for 2 years and my montipora have been growing like crazy. Everything was perfect. Last week I noticed a gonipora was closed up so I decided to do a large water change. It's a 150 gallon tank. I usually do 30 gallon changes. I did a 75 gallon change...
