Hey reefers,
I’ve been storing my RODI water in a 32 gallon brute gray trash can (labelled food grade) for my WC. I also add powerhead and heater to keep water oxygenated and warm (78 F). Out of curiosity, today I checked my RODI for nitrate and phosphate. I found a small trace amount of nitrate (near 0, less than 2 ppm, from RS test kit) and 0 phosphate (salifert PO4 profi test). However, when I checked my water that has been stored in the brute, I have nitrate spike up to 2 ppm, while phosphate is at 0 ppm. Have anyone had experienced the same result? I have some diatom issue, but at manageable level (mostly on the walls and everything in the walls but not so much on the rocks or sand bed). Is this why I have diatom problem? I need to buy a test kit for silicate to see if my RODI water have silicate or not. Other than 10%WC and cleaning the walls. Feed fish once a day. Coral AB+ once a week, 5 mL phytoplankton for my pods once a day. Blue channel at 42% white at 2%. Blue on for 10 hours, white on for 4 hours. What can I do to reduce diatom bloom? TIA!
Tank parameter as of 12/30/20
Salinity 1.026
pH8.2
dKH 11
Phosphate 0.1 ppm
Nitrate 0 ppm
Calcium 460 ppm
Magnesium 1600 ppm
Ammonia 0 ppm
Nitrite 0 pom
Inhabitants in run protein skimmer and HOB fuge with cheato and GFO bag
2 clowns
1 yellow goby
2 fire gobies
1 captive bred mandarin goby
1 pistol shrimp
5-7 hermit crabs
1 emerald crab
3 turbo snails
4 nassarius snails
Other CUCs that I don’t remember the name lol
4 rock flower anemones
Bunch of corals
