Hi all, Using Randy’s2 part recipe I can’t find the magnesium chloride hexahydrate sold by the Dead Sea works company. What other options do people use? Thanks!

Na3PO4 Dosing. Can I safely dose the attached? Some background info: I am running a new lightly stocked tank with some small LPS which is +-4 months old. I ran into some nasty issues and discovered Nitrates @ 0 & Phosphate @ 0 several times using a Red Sea test kit. During my journey switched...

Hello Randy, i wanted to ask you about your #2 2Part, since it is in cups and Gallons. i want to make the mix in 2 Liter container i do not have a better opition. how can i do it exactly to have the mixed balanced. and the part of the magnesium how much grams to mix? i am attaching 2 pictures...

Hello y'all, So i got a triton test result back today with high level of SN, so as the tittle says my question is what is SN and how is it affect your tank and how to get rid of that? Thanks

At precisely 2:45 every afternoon I get a sharp dip in ORP & pH as seen on the Apex. I use 2 Dos pumps that dose Calcium and Alkalinity and the other does transition elements and Acro power. None of the pumps are dosing at that time in the day as checked in the apex log. Does anyone have any...

Since my calcium reactor cant seem to keep up with my alkalinity needs, would it be feasible to dump some kalk into my saltwater container? I've implemented automatic water change of about 7500ml/day. Would there be issues like clogging the lines, burning up my DOS, screwing up the chemistry?

Randy I notice my used Lime Soda I used that was purple turn back to white when sitting out overnight. I didn’t have time to toss it so I left it out in an open container. Does this mean it can rejuvenated itself by sitting out?

Two weeks ago I replaced a broken needle wheel shaft on my skimmer. While I had the skimmer taken apart, I put Teflon tape on the venturis’s threads to prevent micro bubble escape. So now, loads of bubbles but no skimmate. Could the tape be releasing compounds that are preventing foam production??

hi everyone, I have notice recently when I added same amount of two parts (dosing pump checked), my alk is descreaing and cal is increasing. Any thought? Week 1 Alk 7.7 ( correct back to 8.5 by dosing 30ml of alk) Cal 460 Week 2 Alk 7.7 Cal 470

I just tested my Alk and it came up 12.2 dKH, I normally run it at 8.0 and it stayed there up until the middle of November. I did a water change with red sea salt and I turned my doser to 2ml every other day and that was about two weeks ago but now like I said before 12.2, before the water...

Why am I seeing such a low measure of Alk? I measured it at 5.6 today. The Alk was struggling to stay over 7 the last 2-3 weeks. Last year, I had to watch things or the Alk would jump over 10! I'm running a calcium reactor AND a Kalk reactor so this really made me scratch my head. I've...

Hello Everyone, What a great forum! I received my test results back from ICP- Analysis Friday. I would like some input from the Forum about the results. Especially look forward to feed back from Randy Holmes- Farley. In readying the Forums over the last few months. I find your input to very...

I have the Milwaukee Mi412 for low phosphate testing. I have 50+ packets of phosphate reagent that expired on 6/2017. Should I toss it or can I get a few more months out of it? Thanks

ok I feel like I'm not sure how to maintain my levels at a stable point. I did a water change on May 26 and checked my alk and it read at 9.5 dKH(Hanna) I checked it today and it showed 7.6 dKH(Hanna). I want to keep my levels between 7-8. how would I one keep them stable and how would I dose or...

should I get a good nitrate test kit or a good phosphate test kit first? I would like to get both but I can only get one for right now.

@Randy Holmes-Farley if you may ... and I apologize in advanced if this has been raised in the past. By no means this is to compare between Randy's and Red Sea; I just want to understand. I was looking at your Alkalinity part (recipe #1 and recipe #2) Recipe #1 for pH below 8.3 (bake then...

Its about three months im dealing with balancing nitrate and phosphate in my reef tank and im steal dealing. This started when i saw my corals loosing their color and i asked in R2R and they say me that the po4 is too low for a tank that has LPS.So i tried to rise my no3 and po4 but i added too...

I try to keep my tanks alk between 7-9 but when I use my red sea salt(not the pro) it brings my alk back up to 11. I was wondering if I had a bad batch of salt or something else.

So my cal and alk was on the low end reading at cal-385 and alk -7.2 using regular instant ocean. I decided to switch salts and have been doing large water changes every other day however my alk is going up really slowly compared to my calcium. My calcium is currently at 420 and alk is now at...

Any ideas? The shell was clean when I put it in a few days ago and I just noticed this today. I did have some feather dusters on live rock which I haven't seen for a while. This was taken through my microscope - the white part is the clean shell. Total size is 0.5 cm. Thanks.

After my notices on my corals that every time my phosphates is at zero point,my corals first loose their colors little by little and they bleach at last. So i need a way to increase it to an acceptable range because it is 0 with hanna test kits. I tried feeding my corals and fishes more and more...

Hi my friends.Ive started to use kalk for maintaining my parameteres and have watched related videos related to.The first question is that when i put the kalk in the water in a bottle and shake it,after 6 hours the water wasnt clear.Is it normal or not? The other question(not related to kalk)is...

ok I tested my calcium on Monday and it was at 390. I tested it today and it was at 410 and I have not put anything in my tank to raise it. I was wondering what would cause it to do that?

I have brs catalytic activated carbon for rodi unit and rox carbon for my reactors. I mixed the two and just added the one meant for my rodi unit into my reactors on tank. Does it matter or can cause harm ?
