Lowering phosphate

Hi my phosphate levels are pretty high & I think this is due to the amount of tap water i used when I originally set my tank up. Since realising this mistake all my water changes have been done using RO. Other than doing a huge water change - which I can't because I don't have enough RO - is there anything I can use to lower my phosphate levels? If its not possible I suppose I'll just have to buy a large amount of RO & get on with it. Thanks
 
what size water changes are you doing in this case larger ones would be more effective than smaller ones. ou can also try a phosphate reactor I know of two; phosnban (two little fishes, and kent. just want to go slow as they can deplete alkalinity. also want to siphon out detrious and make sure you are not overfeeding as that would also be a major source of phosphate. Another trick is to .. when feeding frozen foods thaw it in a cup and do not add back the liquids strain the solid food out and add only the food bits.

I've only been taking a large bucket out & replacing with RO every fortnight. I feed once a day sometimes once every 2 days. I put a small amount of water into a small plastic top, put fresh garlic in & let approx. 1/4 - 1/2 a cube of brine or emerald tree, let it soak for a good hour then pour it into the tank. The fish love it! I might try doing a larger water change
 
Besides using a phosphate reactor you could also consider poly filter pads and dripping kalk.
 
This is a Poly Filter pad, Ill let the website explain:

Kalk is short for the german word Kalkwasser, it is Calcium Hydroxide or lime powder. The germans used it for taking care of dead cows so as not to spread disease. Aquarist use it to maintain Calcium and Alk levels in their aquarium, it has to be dripped in slowly. Usually about 1 teaspoon per gallon of water is the way it is used. You can do a search on here to find out more about its pros and cons. One of the pros is that it perfipitates Phosphates.

shinna how are your phosphate levels and what did you do to get them under control...
 
Growing macroalgae and harvesting them from the tank is another way to remove phosphate. If nothing in your tank is having a problem, you could probably let the phosphate drop on its own as you do water changes, if you're sure the source was the tapwater.
 
Bought a tub of RowPhos. Put about 1/3 into the pouch that it comes with & put that into the top of my filter with my carbon. I also advise to keep on top of your weekly 5-10% water changes. Within about 3 weeks my reading was almost 0.00! My tank is currently running really well....... touch wood! (English saying if you dont know what that means!!)

Knock on wood, I think is what you were looking for :)

Great to hear your tank is doing better...
