Need some help ASAP. Over the last week or so my SPS’s have bleached out. It started with my Blue Millie, which has since recovered. The last 3 days my blue, orange and green Digi’s have bleached. No new livestock has been added. From a maintenance standpoint, nothing has changed except I added Purigen about a month ago. I added it to my canister and I do also run carbon.
My parameters are:
Ammonia and Nitrite are 0
Nitrate <15
Phos 0
Salinity 1.025
Temp 80
Dhk 9
PH 8.1
CA 420
Tank specs: 45g with 65lbs of live rock, 4” DSB, 3gal HOB refugium, Eheim 2206 canister running only a filter pad, carbon and Purigen (cleaned weekly), Tunze skimmer.
I’m thinking I have overkill running both the carbon and Purigen and thereby removing key nutrients. I added the Purigen to aid in nitrate removal as I’d like to get that down to <5. I did a 30% water change last night.
Any assistance is greatly appreciated.
