calcium and alk

Greetings! I’m generally just a lurker, and I don’t usually post. But I’ve run into an issue that I’m not sure how to handle, and I wanted to see if the crowd here might have some good ideas. Background I have a 75 gal reef tank (probably around 80 gallons total volume). The tank has been...

Question is in bold and underlined, the rest is explanation. I just put in a 2 400gpd RO membrane system in my basement mainly to use for my tank top off and water changes but I also piped in three refrigerators and a few drink fillers throughout my house all ran off of a 30 gallon RO pressure...

Hey all! I am looking for some perspective and insight on getting into this 2 part dosing. Params last week when aqcuired the Neptune Trident. Guessing 160g of volume (150 DT + 55g Sump- sand rock etc.) PH 7.9-8.2 Alk 6.02 CA 386 Mg 1500 (worth mentioning I had been adding brightwell Mag with...

Hi everyone, Setting up a new tank (total water volume will be between 265-280 gallons) New to the world of calcium reactors I don’t have a budget, just wondering what are the best high and then mid range calcium reactors are and what the benefits of one over another are. For context this...

Hi all. Recently I got my hands on a Trident and it has confirmed that something is sucking the life out of my alkalinity and calcium. Before receiving the trident through my normal tests I determined that my alkalinity and calcium was being used up by something of which I have no idea. I have...

Hey all. Been following the community over the years now and finally decided to create an account and become more active. I've been in the hobby for ~15 years now. Went from a 25g to my current 40 breeder (bare bottom) ~5 years ago. Unfortunately, I lost interest in the hobby going on a few...

I wanted to write about this subject as I too started to dig into the world of chemistry and became determined to simplify the thousands of words and simple but yet complicated chemistry equations about Alkalinity. come to find out its not that complicated! So let's uncomplicated Alkalinity...

I’ve been dosing All for Reef for a month now, it seems like a good product. At first it brought my high levels of Alk down to proper levels. Calcium levels has been stable around 440/450. Calcium has started to drop more frequently and Alk has risen back to 14/15KH. I remember watching a BRS...

Hello, I purchased Maxima Clam about 3 weeks ago, and noticed that it's mantle has become flaky and cracked, like asphalt that was heavily salted in the winter (It's more clear when you zoom in on the picture). It's receiving about 150 PAR and has low to moderate flow. Alkalinity is at 8.2...

Hello , I have some serious kh problems over the past 4 months my alkalinity stays above 14 at all time even after wc. But ph is 8.2 My wc water is 8.7 kh And at this point I don’t know what to do or lower it Have tested with Hanna checker dkh Salifert kh Waterbox pen 25 Eheim 75 w...

I read a great article talking about 2 part dosing. My tank is a 150 and 4 months old. It will eventually be a mixed reef but right now it is soft coral dominated I guess. I am not sure if I learned a lesson with SPS as I had a few die. It may be because the tank is new or that I have yet...

I’ve been dosing kalkwasser for a couple months now and my Alk has been rock solid stable. I haven’t tested my calcium because I thought those two would balance out evenly . Today I finally tested it and the result was a tad bit low. I try to keep the same parameters as my salt mix . I use Red...

Tank volume (approx): 44g Stock: low/medium bioload of Softies and LPS Salt mix: IO original The only additives I’ve ever used was Tropic Marin. My parameters were where I wanted them when I began dosing AFR. I’ve been doing the initial dose daily and checking parameters daily for a few weeks...

Everyone knows one of the keys to successful coral growth is stable Alk/Ca. My question is, what is the real definition of stable? Are we talking about a rock solid unwavering alk of 9.5? or is bouncing around from 9 to 9.5 back to 9.2 , etc. ok? Here's my trident results from the last few...

It won’t let me take off the emergency button but anyways I’m having a weird problem with this orange like slime that was growing on my corals and then I realized it was growing in my sump I’ll attach pictures. It’s not cyano bc I think cyano is red and I used chemiclean awhile ago but it didn’t...

Hello, I am having a weird problem. My calcium won't go down. I have been using tropic Marin all for reef for quite some time (powder mixed with RODI), and recently I've noticed my alk and mag are ok (9dkh, 1375 mag) but my calcium is 550-600 (usually 430-460). I lowered my all for reef dosing...

Hi Guys, I've been testing my tank water for about a week and have recently introduced my first batch of coral - 4 small LPS frags along with a small Zoa frag into my tank this weekend. In the week leading up, I was told my Calcium was low by my LFS after I took my water in double check my...

I’m having trouble balancing calcium and alk and unsure of what products work best. I’ve been using seachem with poor results. Also, I’m not sure I even understand how to use them properly. Is there an all in one product easy to understand and use that anyone recommends? Thanks in advance!
