Red Sea 4 part dosing

[FernBluffReef]

Absolutely. That last paragraph is what I’m trying to figure out. It seems very odd to me that CA is so high and I’m fighting to get Alk up. I have a lot of small corals. I don’t think I should be needing to dose this much. Or I could just be off in what I think it takes. I just tested Calcium and it’s at 600. I haven’t dosed any calcium in over a week and yet it’s higher today than yesterday. I haven’t changed the water in a week and only adding foundation B.

Something is off here.

As shared I have a RS525, just a bit larger volume than yours. I have gobs of smaller corals as its a younger tank just getting going. and am consuming 1/3rd the amount of ALK you are. Based on the pics you shared I can't fathom that much ALK consumption. You have a good amount of coraline going which is great but still...

I'm new back into the hobby within the last year so have to let other members experts here guide any deeper as to what might be going on. 23 years ago I had a much larger tank and dont recall ever dosing that much but the variety of corals I had back then are different.

Below is a pic of mine for comparison . Again I'm using 16ML of Part 2 / Foundation B at this point.

BTW. How are you testing salinity?

I have experienced the same issue. I am using Red Sea 4 part. I have a RedSea Reefer 250 and my Alk is 8.77 dosing about 20ml of part B and was dosing 10ml of part 1 but I my calcium shot up to 578. I cut the part B down but calcium kept rising.

I’m trying to just slightly adjust the dosing amounts based on each element and potentially just turn off the part B dosing.

Hoping anyone can provide more ideas or experience.

I was able to get my calcium down by shutting that head off while continuing to dose the other parts. I can also blame a little of it on testing. I was using a Hannah checker but I wasn’t cleaning the tubes well enough. Once I started rinsing the tubes in distilled water before testing, cal num was weren't as bad. Still high but manageable with water changes and shutting the head off for a week.

After that week off did you turn it back on with the 2-1 ratio of part 1 to part 2 or with a different ratio?

Thank you

I turned it back on to the ratio they prescribe. Parameters are now perfect.
