forgot to ask...optimum ph 7?

just under 7, but anywhere 6.6-7.5

If you're below 6.0... and you may well be... you dont want to move the pH by more than 4 points at any one time/day... so bring it back with a handful of slaked lime... and see what reading you get...

Then I'd move it back incrementally over a week.. to about 6.6-6.8....

thanks Rupe, its up to 6 atm with little bit at a time approach

Jezz.. as Monya suggested... must have been down around 5...

Will take a day or two for the bacteria to kick back in... how's your ammonia??

No feeding...

ammonia low....yep, no feeding daily water testing and adjusting accordingly.

btw, does this sunray salt provide any trace elements for the plant growth??

Undoubtably.... sea water has a very high concentration of all trace elements...

As the Sunray salt is pure evaporated sea salt... it would have good trace element availability...
