2 year established tank tweaking

[dnguyen1]

Hey guys my measures are the following:

8.3 alk
450 calcium
1400 mag
1.023 salinity
I fed fish every other day and then once a week for reefroids
-
70g pennjnsula
40g sump
5 fish (clown pair, firefish, purple tang, melanrus wrasse)
-
I was losing a bit of color most likely from polished water of not feeding enough.

I shifted to feeding daily two times and reef roids every other day and I got my levels up and things look more colorful

Measurements now have changed where no3 is 5ppm and po4 is .18

From what I understand I can go a bit higher on nitrate but my phosphates are too high already?

Can anybody give me advice on how I can lower phos but increase nitrate or if there was a flaw to what I am doing?

I dose alk and calcium and acropower

You could try Phosguard or an equivalent in a media bag in your sump, or a reactor if you have one. That should just reduce Phosphates and not Nitrates. That's what I plan to do if my Phosphates get too high compared to my Nitrates. Or you could dose a little Lanthalum Chloride, same deal, only reduces Phosphates.

I'm similar to your levels - .12 ppm Phosphates and 4 ppm Nitrates as per last test. For now everything seems happy, so I'm leaving it alone.

If everything is happy and you have no major algae issues I'd leave alone. Definitely DO NOT dose lanthanum chloride into an established tank. If will definitely bind to the phosphates but will form a fine sticky powder in the process and get onto everything. The powder will be taken up by filter feeders--like corals--and kill them.

There are threads here where folks dosed a slow drip of lanthanum chloride into a very fine mesh filter sock w/ success. So it is possible, but do your research before you attempt so you don't turn a small concern into a big problem.

You already increased feeding a bit, but I'm a big fan of huge increases. Natural reefs have been measured at a pound of food particles per cubic meter, per day.

You might think about increasing your specific gravity a couple points.
