I ask this question because my ALK & CA usage has skyrocketed! I am currently dosing 400ml a day of each to maintain ALK at 7.8-8.0 & CA 415-420.
Now that could be average for a tank this size which is why I ask the question.
I am slowly increasing the levels daily, sometimes multiple times per day to stay at those levels. Target of 8 DKH & 420 Calcium.
Slowly meaning 10ml-20ml adjustments. But within two months I have gone from 100ml of each to 400ml of each daily via Neptune DOS being dosed automatic over 24 hours.
Background: 225gallon display / 240 total water volume SPS dominant.
Tank is a year old & testing is via Neptune Trident 6 times per day. Trident is calibrated every time reagents are replaced.
Neptune DOS gets calibrated monthly.
I keep PO4 .02-.10. I have to dose PO4 almost daily based on results via Hanna to keep from bottoming out.
NO3 12-25 via Nyos Test kit tested every other day.
MG 1250-1270 via Trident
Dosing: ESV Bionic 2 part never used anything else.
ESV Magnesium by hand as needed
Corals have good color & are growing fast. New growth on all...
I have 58 SPS frags throughout with Marco rock scape. Some frags 3“-4”in size. Rock is 100% covered in coralline.
I decided to install a CO2 scrubber two months ago and my coral growth & ALK/CA consumption took off.
PH was 8.0-8.2 prior to CO2 scrubber. PH with CO2 scrubber installed is 8.3-8.45 changing out the media weekly. I run my fuge light 5.5 hours per night to keep night low PH of 8.3-8.35.
Do these dose levels seem normal for this size tank with SPS frags?
I am not complaining I just want to make sure something isn’t off and I am not over dosing.
If this keeps up I will be switching over to a calcium reactor. Already looking at the Deltec CRTT 1500 as an option if needed. Open to other suggestions but I like the automated as I travel often.
Thank you
Lance
