Red Algae Invasion VS. DIY XP2 reactor! More Advice Needed About a Product.

[Blakes Living Reef.ca]

You have a cyno bacteria which will take over your tank and may harm your corals. Your live rock and sand(?) are more than likely saturated with phosphates. You need to remove all of your live rock/sand and place them in a covered, heated tube for a period of 3-4 weeks (or more) with a small skimmer or water changes (every 2-3 days). This will allow your rock/sand to re-cure. Clean your rock first (toothbrush works great) and re-clean at each water change. Only place back into your main tank when water stays clean, rock smells and looks right. This sounds drastic but just adding chemicals is wrong! You have to find the source of the phosphates and eliminate them (overfeeding/overstocking). I have found adding a Phosphate Reactor to the system along with good Reverse Osmosis water will prevent further issues.

yeah, that would work too. But more likely than not you are simply over feeding. That's what happened to me.

Yes we have discovered that it was an over feeding problen. I have a few corals that like to be feed and have had recieved some bad info about a few other that don't need to be target feed. So now I am only target feeding a couple of my coral that close over the food right away and eat it all and not the rest. going to check phos levels again tonight and have ordered some Zeovit Coral Snow. Removed all the red algae ( was not slimy) peeled of in a fine sheet, small piece's that I could see and get to. As I have a 155 with about 80 lbs of sand and about 100 lbs of rock removing it all to clean and kure again is not really an option right now.

I have a whole house RO system (massive $$$) Water quality better then store bought. I think I will invest in a reactor. Got any sugestions on what to get?

I use Two Little Fishies PhosPhate Reactor 550 with their PhosBan Media on my 140 gallon with great success. They also have a smaller unit , PhosPhate Reactor 150.

Do you run then from your sump or out of the main display tank?

Could I use a Rena XP2 Cannister filter to make a phos reactor? Sandwiching PhosBan in between form in one level & do the same for carbon in the top level.

May work, the only problem i see is that your flow may be to great and turn your phosban into a fine powder which could then be flushed out of the canister and be useless. Phosban granules are fairly soft just the action of grinding against one another under heavy flow can pulverize them.
Canister filters also tend to become phosphate generators if they are not kept very clean so keep a close watch on it if you go this way.

[The Grizz]

I have a flow valve that came with the XP2 so that you are albe to decrease the flow or even shut it off completely. I would also use a filter bag if needed. When I was using the XP2 on my 65 gal SW I would clean it every 3rd day.
