reator help

[jones02]

So I'm going to be addinng 3 reactors to my tank, gfo, carbon, bio pellets. Will it be bad putting them all onn at once? Will it be to much change to fast? How should I do it, and what amount of media should I put in to start. 90g with 37g sump.

it really all depends on your current levels. If you have high phosphates and nitrates, you gotta be carefull. Dropping phosphates too fast is worse then having high phosphates

Ive heard your not suppose all three!!  it can cause massive algae out break. id run either GFO carbon or Bio pellets

I run all three....no problems.  I wouldnt suggest putting all these reactors online.  If you can test your PO4 with a hanna and NO3 with a quality kit to see what you are working with.

I'm ordering a hana on my brs order, I have a cheaper one and I just tested it and it goes from 0-0.25-0.50 and so on. And its between 0-.25

IMO  once you get your pellets tuned in you should have none to very little issues with phosphates,i dont use GFO and i usually had a near zero reading for phosphates,everything i have read including the manufactures web site they do not recomend using GFO with the use of pellets,i believe the bacteria the lives on the pellets consume phosphate as a food source and in turn is removed along with your nitrates,even when i was vodka dosing i never had any issues with phosphates

•Bacteria require small amounts of phosphorous to metabolize nitrate properly and phosphate levels theoretically could be a limiting factor for this system. For this reason we recommend not using phosphate removal products like GFO during the initial phase where are you are trying to lower your nitrate levels.  Once you have the nitrate levels down we recommend continuing the use of GFO to maintain optimal parameters in the tank. You may find that your GFO lasts longer when used in conjunction with the bio pellet system. We find that the Hanna PO4 checker is the best tool to test phosphate levels because it gives easy to read reliable readings.

so you need to find the po4 source,take action and the pellets in therory should slowly and safley remove both phosphates and nitrates
