Got it! So I can stop testing twice a day then LOLDont worry about magic balances as we rarely achieve them. However your goal is to get into the .1 range and I dont see an issue with it. I run PO4 by choice around 0.08 - .1 and no issues. What works for one's tank may not work for another and will depend greatly on water used, feeding habits, tank size and type/number of corals in the tank.
Chasing numbers is a no-no however and focus on ranges in lieu of target numbers.
What a gorgeous tank! One day I hope to have one exactly like it! I tested this morning and I'm at .12 N and .52 P. No GHA in sight and I don't even know what cyano looks like. I did battle GHA and Dinos HARD for the first year and lost a lot of fish and almost all the corals due to it. I finally read somewhere to just black out the tank for 3 days and once I did that, twice in a month I've never seen GHA again, except for a single trochus snail who was covered in it. I let him live for a month and it never went away so I tossed him in the ocean as I was scared it would spread. So for last 5-6 months the tank has been perfect minus the high numbers. I will leave it alone! I do have a heavy feeding hand...I am a sucker for my cowfish begging me for food. I feel a lot better, I mean I have a cowfish, non-photosynthetic gorgonians, overfeed for sure, 26 corals and 4 fish in a 20 gallon tank...duh. I do want to get to a balance of smaller water changes/less frequently but I will take it slow and hopefully get there one day. Or just bite the bullet and go all out with controllers and AWC etc hahaHow high have you let them get? Often they'll increase then level off. I think one of the problems is most people have read that they should be low, like NO3 10 or less and PO4 0.05 or less so they take action to reduce them which is fine if that's your choice but it usually becomes a constant battle to keep them low. This is just from personal experience and not a recommendation because each tank is different. I let my tanks run and see where N and P end up settling at and as long as coral are looking good and I'm not battling nuisance algae I let them run at those levels. I have 3 tanks running and each has settled in at different levels. The one I have the most trouble with is the one that has barely detectable levels and it's full of nuisance algae. The tank below ran for years with NO3 20+ and PO4 0.3-0.45 Early in I was running gfo and I always had gha. I stopped and just let the tank run doing occasional water changes and dosing kalk. This is the tank after 8 years
Pure speculation on my part but I'm starting to think we see so many posts looking for help with nuisance alage, cyano etc are because folks are trying to control too much and not letting the tank settle into a natural balance. I think this is especially harmful with newer tanks that are never given a chance to obtain a balance naturally. I'm not a science guy and am still learning but I really love being able to keep things simple and just enjoy the tank instead of fretting over it.
EDIT : Sunnyx who has tank of the month posted in the thread I linked above and stated his PO4 is 0.9
That’s 2 funny!! I wouldn’t dare play with Algae like that after what I went through! I think perhaps the reef roids I’ve been feeding may be the culprit more so than the feeding. It’s what I read anyways so moving forward I’m going to just stick to frozen, dry freeze mysis and live baby brine shrimp I’m hatching once a week. I actually want to see if I can grow the shrimp in a bucket so the cow fish can enjoy them also. Currently he doesn’t even see them, but the other three go bananas over them. Oh and nori for the cow fish. I will go more frequent and less. Btw the pellets may have been the culprit behind my GHA as they were in AF dropping daily before lights out. I kept noticing that some would go uneaten and be in the sand decaying.I feed so much I'm surprised my levels aren't higher lol. I keep 4 kinds of pellets next to this tank for treats and have started pulling alage out of my scrubber and tossing it in the display several times a day. I just can't say no to these guys
What’s up with the back wall? Should I not be cleaning mine and let whatever all that barnicle looking stuff just grow?Sounds like you have a good plan

This is the tank that replaced the one I posted above. This one started with all dry rock and barebottom but I put a bunch of rock in the sump from the old tank. Levels are pretty close to what the old tank ran NO3 13 and PO4 0.39 last test.
It's a personal preference. Many folks love a nice squeaky clean look which is great but I'm too lazy. I've never cleaned my back walls. The tangs graze back there all day so I figure it's benificial, at least that's what I tell myself lolWhat’s up with the back wall?

I need to stop hovering around the tank and be more lazy! Thank you!It's a personal preference. Many folks love a nice squeaky clean look which is great but I'm too lazy.

I love cowfish!With whites and blues all the way up.
