Hi I'm having difficulty rising my Cal/Alk levels i have increased dosing from 55ml to 200ml 116 gallon tank.
Previously 55ml to maintain DKH 8.0 and PH 7.7-7.9 up until 10.02.2020 when i noticed C Balance Part B was not being added by Apex dosing pump as tube was not fully submerged in bottle.
10.02.2020 DKH 5.1 PH 7.82 In order to counter Part A started Dosing Part B extra from 55ml to 80ml over few weeks while part A remained 55ml
12.02.2020 Added C02 Scrubber
Current parameters 04.05.2020 with 200ml C balance 1:1 A and B
Salinity 34ppt
12hrs later DKH 5.5 at 23:45 PH 8.28
DKH 5.7 at 11:45 PH 8.15
Calcium 415
Mg 1290
Please help me understand what is going on with my tank and how to fix this issue. By the way most of corals are still growing faster while 2-3 have partial bleaching.
Its SPS dominated tank i have 3 colonies and rest frags i can share picture there is a lot of coralline algae.
System
Red sea reefer450 116 gallons total system volume (actual water volume unknown)
Skimmer, Bio reactor (2 little fish bio pallets in small amount)
Reef Octopus LR-150 Cheato Algae Reactor
Chiller
Marine pure block and balls
Phosban Reactor
C02 Scrubber
Ozone generator
Light settings from 10:00 till 23:00 I also get indirect sunlight throughout the day
Supliments and Salt
red sea coral pro
Acro Power 15ml/day
Iodine 5ml/week
fauna marin min S 2-3 per week
Vibrant used only 2 times once after every 2 week
Detailed History
02.04.2020 DKH 7.0, Calcium 425, Salinity 35ppt, C balance Increase Part A and B to 85ml 1:1 ratio back to normal
10.04.2020 DKH 6.7, PH 8.41, C Balance increased to 100ml
19.04.2020 PH 8.4, ORP 250 Installed ozone generator
20.04.2020 DKH 7.20
24.04.2020 DKH 6.0, 40L water change Coral pro salt
25.04.2020 DKH 6.2 at 16:00hrs
28.04.2020 DKH 5.3 at 10.30pm Increased C Balance from 120 ml to 140 ml time 23.00hrs
30.04.2020 DKH 5.3 at 13:00hrs, Calcium 415, Phosphorus 0, C Balance Adjusted from 140 to 160 ml at 17:00hrs
01.05.2020 DKH 5.2 at 15:11hrs, C Balance dose adjusted from 160 to 180 time 22:50
02.05.2020 DKH 5.1 time 12:00hrs, Calcium 410 Possible cause precipitation issue due to location (skimmer chamber in Sump) and dosing C balance at same time without interval.
Changed dosing interval to 5mins and location to Display tank near high flow 16:30-17:00hrs
DKH 5.1 at 22:15hrs
03.05.2020 DKH 5.2 at 03:50hrs, DKH 5.3 at 12:40 PH 8.14 ORP 343, DKH 5.1 at 20:35hrs PH 8.31 ORP 334, Water change 40L 23:00hrs, DKH 5.5 at 23:30
C Balance Increased dose from 180ml to 200ml/day from 00:00-23:50 every 15mins with 9 mins interval between Part A and B
Thank you for all the help i can get
