PH problems need help asap!!!!!

[jonzee2006]

Has anyone using neomarine salt had any problems with keeping their PH up? I've been using it for about 3 months now and all of a sudden my PH just for the life of me stop dropping. Normally my PH is 8.2 at night and 8.4 during the day, now its 7.5 at night and 8 during the day. My Alk is at 9.6, Mag is 1300, and CA is 450. I've been dosing with brightwell PH+ to try and raise the PH and hopefully stabilize. Pretty much all of my corals are dead so now I'm trying to get everything back in order so I can make a come back. So please help!!

api is junk!!!!!!!!!!

I'd definitely pick up a higher quality test kit or digital probe. I highly doubt the 7.5-8 swing is what killed the corals, mine swings from about 7.7-8.1 daily and has dropped significantly lower with no issues.

How big is your tank? what is your substate if any. how do you dose Alk?

it's a 72 bow with a 20 gal sump. I dose brightwell Alkaline 8.3, Liquid Reef, and brightwell mag. my alk has been steady at 9.6. I use salifert test for my alk, ca, and mag.

I agree, double check your PH and get a meter.
