GFO

[Tracy G]

I am getting a good amount of algae growth on the sand (brown Algae) and I clean it regularly. My levels stay at 0 and I feed my fish daily. Would running GFO help? Tank has been setup for 5 months (except changed from 72-40 gallon 1 month ago). Should I go with GFO? Feed Less? Or just give it time? Any help you have would be great!

What level phosphate?

How do u measure it

[Tracy G]

Just realized I can't.....lol. I only measure PH, KH, Ca,Mg, ammonia, nitrate, and Nitrite...... Would you assume it was higher based on that? I do use RO/DI

[Fishie]

If u don't have a phosphate test calorimeter...maybe u can have a Lfs test phosphates

Gfo helps bring it down...

Acceptable usually is around 0.03

 

Using rodi is good but sometimes u can get sand or rock that leech phosphates into the tank

 

Brs has decent phosphate reactors...and some dual stage...where u can do carbon and gfo ..

[Fishie]

It could be nitrates too...if u have a sump throw some cheato in it to bring nitrates down...what are they at ATM?

[Tracy G]

Nitrates were at 0 right now. I know you can run carbon and GFO together. Just heard it was expensive

[Fishie]

I believe a single stage reactor is like 25 something...dual is maybe 45-50 new...

Then the carbon and phosphates u can buy in bulk

 

I think I have an extra dual stage lying somewhere in storage..but it needs adapters for either end

 

Check out brs...lots of options

 

Personally I would prefer to run them separately ...its not a big deal but has something to do with the flow rate being different for both for optimal results.

[Tracy G]

Just limited on space even a single would be tough to fit. It would sit in the water most likely. (of sump)

[Fishie]

Then u may want to look into sock options...
