I have got really high phosphate levels (more than 10ppm) scince i dicovered this i have done 2x 25% water changes and add a phosphate remover I am not overly worried as it has only been a couple of days but the phophates arn't going down yet. For filtration I have an external filter (900lph) internal filter (900lph) and Two under gravel filters. I have alot of rocks in the tank with algea growing on them could it be that the algea is containing the phophates and releasing them? and if that is the case is it worth putting them in a bath with some janola to kill al the bacteria?

Or should I just be patient and let time and water changes fix it?

regards,

Daniel

I had the same problems, just part of new tank syndrome. Give it a few weeks, kepping up the water changes and keeping the algae in check and it will come right.

I have also dropped feeding to once every two days

Have you tested it from the tap? Some areas have high phosphates in their water.

yeah I done that today hoping that was the problem but the result came out clearer (less coloured) than zero on the phosphate chart, hence the reason i am considering the algea still releasing phosphates. Although I only know the orriginal reading was more than 10ppm as that is the highest the chart went and it has defenatly come down a slight bit (in colour) but is still at the 10ppm range. I think like all things to do with aquaria it is better to take things slow even doing the right thing to fast in many cases can be terminal

How long has the tank been setup for and what type of phosphate remover are you using?

That tank has been set up for 3 months but the filter gravel and water has been in constant use through my tanks going back 19 months

and the phosphate absorber is jbl phos-ex
