Hammer and Duncan's closed

[SALTWATER_JUNKIE]

11 mo old tank. Duncan's were doing good but now closed for 2 weeks. Hammer the same. Dealing with gha now. Wondering if it's due to no3 and p04 or too mu h flow. 75 gal + 20 gal sump. 2 1300 GPH WM and 2 850 GPH WM. 2 on each side of tank blowing across and upwards. Lots of movement on my gsp. Both are in sand bed.

They like some nitrates in the water so it may be due to the lack of them

Must have no3 and p04. I have gha. There masking readings I'm guessing.

Lights seem ok. I use the viparspectra on a 40b. My blues are 18 and my whites a 1. However I run my whites from 4-8. I found anything longer grows too much algae. Also are you running activated carbon?

Yes bag in sump. Also bag of chemi pure blue as well. Protien skimmer running wet
