question on removing phosphates

Is there much of a difference between throwing a bag of phosguard in my canister or using a reactor with it in it? And what would the difference be?
 
If you can control the output flow of the canister there is no difference. Aside from pump strength. Some medias require lower flow and some higher. Since a reactor usually has an external (from the actual reactor) it can be matched or adjusted with a valve, which you could also install on to a canister.
 
After answering I realize why I don't like using a canister as a reactor. Because I can't see into it. It helps to see the media, stuff like gfo needs to just be tumbling.at the top or it may crumble. Its hard to adjust the flow when you can't see the media tumblimg .
 
Makes sense, I guess I'll get one down the road as things are a little tight right now, the canister only puts out about 150gph so should that be ok for now with the media?
 
i would go from something like chemipure elite. that has been solid for me whenever using a tank with canister like now. or on a nano. i dont have any phosphate issues. there are other products that work well in a canister type situation. and gfo isnt one of them. you need to see that and be able to adjust it via external pump. tell us about you tank
 
Why you need to see the media in a canister filter? It's not moving anyway :)

The reactor is believed to be a better, more complete way to use the filter media. In a filter bag, depending on multiple factors the bag, media will clog. Water has the property of moving through little channels through the media causing some of it to never be used as water is not moving around the media particles. A reactor ensures the media is completely exposed and the whole media quantity gets used.

Very true.
This media should not tumble and a guaranteed flow through is how it should be used.
 
in a reactor you can verify that the media is tumpling like its supposed to. i had to really tune the reactor in from BRS with a mj900. also with the carbon. thats why i like having seperate reators. and its better to have a reactor for the flow and not having a bag clogging up. i guess i wasnt being clear.
 
I have a canister with matrix and the searches nitrate stuff (I know the nitrate stuff won't work at that flow for the nitrate itself as I've read, but it does the job still for ammonia and nitrites) as well as a bag of carbon in there. I have a protein skimmer rated for 120 or so gallons, forget the name, it's a 60 gallon tank, about 40 pounds of live rock, 4-4 inch sand bed, tank is 3 months old, cycled it in about 2 weeks. Decent flow, I might get one more power head, i've been dealing with cyano now though, no readings from ammonia and nitrite, 2.5 ppm nitrate, just ordered the phosphorous kit yesterday. Using r/o water.
