Best Phosphate adsorption

[sen5241b]

What works the best? Rowaphos, Phosban? I am not interested in aluminum based adsorption. Also what's a cheap place to buy it? My 20G long has been plagued by phosphates for too long.

i run 2 little fishies bioplastics for phosphate and nitrate removal. having good success with positive effects on my reef. the best part is that you never change the material only add more as it dissolves over time.

Heard at MACNA Rowaphos was going to do a major price drop due to a change in sourcing. May be comparable in price to the others shortly

Where are the phosphates coming from? Check your food or water source.

That is an excellent question. We have 2 clowns, one kind of large, a tiny green goby and a coral banded shrimp. Don't think I'm over loaded. I have about 18 pounds of rock. I have a 3G fuge with strong flow and about 25 watts of florescent light BUT red slime grows on the cheato in there. Much of the rock has other algae on it but not to plague proportions. My current theory is that there is not enough light on the cheato. The cheato is not growing.

 

So, answer is I don't really know.

Water changes!...BUT...The point Coral Hind is getting at is you have to find the source of Po4, if it is in the water your putting in your tank, water changes will do nothing but make it worse! What kind of food are you feeding? I would check your freshwater supply first! How old are your filters and RO membrane....I assume you are using RO/DI? If you have acess to a TDS meter I would check your makeup freshwater to see what the levels are in that too. The TDS wont measure PO4, but it will tell you other if other stuff is in there.

Just a reminder: Phosphates are an integral (and important) part of living cells. DNA, for example, has a phosphate backbone. So, if the food you're feeding is comes from formerly living cells, there will be a phosphate component in it.

I use the same food that I use in my 29G and it does not have a problem with phosphates. My corals in that tank are fine. I also use the same water -distilled water. The food I use is "Ocean Nutrition Marine Pellets Formula 1 - Small pellets" The phosphates remain! Rarely we put a pinch of flakes but its not enough to account for that much phosphate and resulting algae. Cheato needs strong light and flow. I am adding light.

I've had good luck with the BRS reactor with the high density GFO. Phosphates unmeasurable with it. .06-.09 without it.
