Marie - you just did a major re-aquascape that increased flow throughout your tank and should help with dead spots where algae gets a start and can thrive. Why not wait 6 weeks and see where you are with nuicance algae.
Change one thing at a time.

Dave was just over to test the water.

The nitrate tested at .3 ppm
Unfortunately he had ran out of the phosphate reagent so I will have to wait for that

Your right, but it will be at least another 4 weeks before I'll have time to even think of additives. Who knows what I'll decide to do if my phosphates test as low as the nitrates

I just heat tested my phosphates with an elos test kit that i've had for over a year (expiry date??) and it appears to be somewhere between .01 and .05...a hint of blue but not quite dark enough to be .05...I hate these stupid test kits :lol:

I orederd new test refills today supposed to have them Thusday.

Okay, My nitrates are 0.3ppm and my phosphates are 0.022 (heated) as per Dave's colorimeter....that seems awful low considering I haven't done a water change in at least 3 weeks

But Remember Marie PO4 is PO4 if you have some type of sort of Algae then you have PO4. however some PO4 is great for tanks and some isnt

I realize Mike but I don't have "out of control" algae and considering I haven't ran any phosphate removers in the tank for the last 2 years I thought it would be higher than that.
I suppose it is a good thing that I have so many different types of algae that non can gain supremacy and take over the tank :lol:

Not bad for a low maintenance tank and will explain your great coral collection.

But if you want to be rid of algal issues and see even better colouration results then you would need to get both these levels down.

Hi Marie,

The old saying if it "aint broke dont fix it" strongly comes in to play here.

If you are happy with the tank as it is then do not change anything, but if you want to start some interesting food regimes for better colouration or other advances then these level would need to come down.

But the important thing is for you to do what you feel is right for your tank, we as outsiders can only advise, and still flick back to the first photos and admire at your great achievements ;)
