Is it ok to dose Phosphate-E and Microbacter 7 at the same time?

[Smaier]

Hello,

My tank is 55 G Mixed Reef with live rock and sand. Eheim Canister 2028 filter, GFO reactor, and Red Sea Deluxe Skimmer and Carbon. I know it is not a good idea to use the canister filter system.

My tank is pretty stocked with Fish Fox Face, Yellow-Eyed Tang, Yellow Tang, 2 clowns, wrasse, diamond goby, dragnet, Naso Tang. 9 total Fish

I am looking to lower my Nitrates. My Phosphate as reduced to 0.1 but my Nitrates are at 50 ppm.
I have been dosing with Phosphate-E and want to use Microbacter 7 in my tank to reduce my Nitrates to 10 or below. Will dosing both chemicals harm or crash the tank, fish, corals, and inverts?

I am doing 10-15% water changes every 2 weeks, vacuum the sand.

Thanks for your help.

Phosphate e appears to be lanthanum chloride. (Chemically blasts Po4 off the rock to be removed mechanically )
I’d actually be more concerned with using gfo and phosphate e together.
You don’t want to zero that Po4 out.

MB7 is bacteria and I belive has a slight organic carbon component.
That’s actually what you want for the no3.

Keep the canister filter clean and you’ll be fine.
The po3 is likely being removed by the floss in there.
