Bottoming out nutrients

[agamblinalot]

My PO4 is 0.0 and my nitrates are 1.4 according to my Hannahs. Two changes…1) I added an auto aqua AWC light and empty my return chamber twice a day. Equates to 4 gallons a week on a 15g system. 2) started feeding LRS nano reef frenzy.

Obviously I need to cool it on the water changes but I did the same amount prior to the AWC just all in one day. Why would this change cause my nutrients to bottom out?

I don’t want to dose phos or nitrate. Should I just feed more? I still have small bits of hair algae that won’t go away.

Made me look, Ha! The AutoAqua Smart AWC Lite, the 25% per week is fairly aggressive for automatice water changes, from what I have read others reporting?
Feed more, slow down the AWC flow if you see the corals suffering at the current parameters?

“I don’t want to dose phos or nitrate. Should I just feed more? I still have small bits of hair algae that won’t go away.“

Bottomed out inorganic nutrients will not eliminate hair algae: consumers & competitors are required.

Feed the corals directly something like reef Roids and RS ab+, move on from worrying about inorganic nutrients values with hobby testing. WC amount is fine if done correctly.

Do you have sufficient CUC to get rid of the algae?
Have you tried to manually remove the algae?

I watch and try to listen to what my tanks wants. Your corals look great, fish look healthy, I don't see any algae but you say you see it....... I don't see any signs that your tank wants more nutrients.

I would feed more or dose N and P, rather than adjusting water changes since they are useful for other reasons. :)
