honestly I don't know lol. I have no experience or knowledge in the area of reactors.
just need to get nitrates under control.
I am running a skimmer E SHOPS rated for 100 gallons on my 65 gallon tank.
my gut feeling is my rock and whts left of the sand bed are just saturated

i honestly don't have a clue what i want in it.i have no knowledge or experience with reactors. just need to get nitrates down.
thanks pilot mike.
when you say run mb7 with the pellets. is there a certain brand of pellet you suggest

I use the Vertex bio pellets as well. Here are some instructions from them.

And these are the MB7 instructions. I dose it about 2 weeks before starting the bio pellets, and then ongoing.

You can get everything you need at J&L.

have a look at the cad lights nr-1; has pump on the reactor and also hob

just a reminder; to add bio pellets slowly to the system
be patient...
