i don't run GFO......just the water changes & the vinegar.
Honestly, I have no clue what my PO4 levels are. For this set up I wanted to let my coral colors on my acros & algae growth dictate how much I wanted to manage nutrients. In other words, use my eyes more than chase numbers. I get a light film of algae appox after about 2 days.
I'm pretty sure I'm not below .10 PO4. I should probably borrow a Hanna & check it for curiosity sakes. I sold my old meter about 3 years ago.
I have a few acros that are canarys & use the colors on them to give me clues.
I believe too many people knock down the nutrients too low & that's when problems happen. Some algae controlled by snails is a good thing.
When you look back at all the old TOTM those guys all had nice bright deep colors unless the acro was naturally light. That was before we could measure PO4. The tanks rocked with high par.
That's what my goal is with this tank natural pastels like say for Pearberry or say a light deepwater, & rockin deep bright colors for the other acros.
Too often now it's all pastel on most tanks I see.........people have gone too far.
Thanks for the reply man; I completely agree and subscribe to the same methodology. I recently got a hanna low range and was pretty surprised how high my po4 was, yet my coloration and growth is pretty good IMO. I'm hovering right around .08 and am hesitant to try and bring it down when things are doing so well. I may start to mess around with vinegar a bit to see if I can cut down my GFO usage. What brand of vinegar do you use?
