Phosphates in fish food
I'm curious about the relative amounts of PO in various foods we feed our fish and corals. I feed mine a homemade frozen mix of Whole Foods bought fresh fish, shrimp, mussels etc..., frozen mysis and rod's food, dried Omega flakes, nori and frozen cyclopeez now and then. That's pretty much it.
I wash the fish etc, and put it in a blender. Once it's mush, I freeze it for use over a couple to three months. I'm wondering if its this that is causing my PO problem. Thanks! |

there are phosphates in all foods, it contributes to phos issues but may not be the cause after awhile LR starts to leech back phos back into our systems. what are you using for export?

I'm using a ton of GFO. I use it in a cannister (about a cup and 1/2) and change it every few days. It's really worked on my Hair Algae, but its also getting really expensive! I am aware of the rock leeching issue and will deal with that if I can't reduce my PO through lower PO foods (and perhaps less). Thanks!

If you are having to change out GFO every couple days I doubt it is a food PO issue.... what are the levels?

The levels are well less than .03. I use the Hanna ppb meter and it rarely shows as more than 5 or 6 - which is half of .03. Could the rocks be leeching that much phosphate?
Nitrate is zero on Salifert. I find that if I don't change the GFO that often, the hair algae starts to reappear. I'm hoping that once it is entirely eradicated, I will be able to return to a more reasonable regimen for gfo. |

Does the GFO tumble in the canister? if the levels are less than .03 you are doing ok with it.

I think it tumbles pretty well and I know that every time I change it the HA takes a beating so I'm sure its a phosphate issue. It just seems that to get rid of the HA you have to have as close to zero PO as is possible and still support life.

Probably just lanthanum chloride. You can get it cheaper at pool stores. I think you are supposed to dose it with a very fine micron filter sock though.

I've been thinking about trying lanthanum chloride. What would it be called at pool stores?
