Phosban reactor vs. GFO

So I've had a GHA problem for about 2 months without resolve. I've done all the normal stuff(cut down on feedings, water topoff with RO/DI, nitrate & phosphate low...I know that algae can make these low...) My lights are 3 months old. I pull the junk off every week during my wc's and it all grows back. I installed an extra powerhead( I now have 3) and a UV sterilizer. I'm currently running GFO in my canister filter...would a phosban reactor be a better choice?? I noticed no difference whatsoever when I added the GFO. I'll make the investment if it will be a significant advantage over the GFO in my canister. That is if phosphate is even the problem.

 

ro/di?

fuge/sump better choice than fluval

 

The filter should be fine, I would go along with reef_guru and say that adding a refugium will greatly help. I just added one to my sump, it cost next to nothing. I had little cyno problem and it's already much better since I added the cheato to the refugium.

 

Respectfully...many aquarists with a refugium still are plagued with GHA. Since I added a Visa Aqua Phosphate reactor (nearly a year ago) no GHA. It took about 3 weeks if I recall for most of it to die off.

 

It may not cure your situation but GFO does work better in a reactor. Slower flows equal longer contact time which is key with products like that.

 

what are your exact water parameters?

There are many factors, including external ones (ie: windows, temp, etc) that could have an affect on your gha problem.

 

anything in there to eat it?

 

Mexican Turbo snails but they are also bulldozers when it comes to moving corals around too. They rearrange my corals or a regular basis, I think its to force me to pay attention to my tank!

 

I've got a clean up crew(snails andblue hermits) won't touch the stuff. Nitrate-10, nitrite-0,pH-8.6, Calcium-390, haven't tested Mg in a few weeks but it has always been fine, Phosphate-0, dKh-12.

There is ambient light in the room, but nothing direct. I was thinking anout covering the tank with a sheet during the day for a week just to see if anything happens.

 

Gha.....

I was gonna say, give AZDesertRat a ring. Anything water parameters, filters, products/chemicals......"He Dah Man"!!!8)
