Still waiting on the ICP test results. Meanwhile lost the last piece of a torch. 1/2 the zoas are not opening. This is just awesome. Liking waiting for the ending of a trainwreck.

Got the results and besides low iodine I am not sure it’s that bad

Ro/di has elevated silicon

Do you have diatoms issues? Silicon being the main component of silicates...

No nuisance algae except some bubble algae in the overflow.

Coraline has covered all the rock and allot on the back glass.

Yet corals don’t last. My guess it’s the lights. Gonna drop the radions down to 40% and switch to los template which is mostly the blues leds only.

Yes if you have coralline usually that means everything is in order.

If you cannot rent a PAR meter, Apogee makes a USB one for around $250.
