I have thought this as well. I think with h202, you clear the surface of life and the algae takes back over. My snail shells are a perfect example. I would hit them with h202 and they would look good for about a week and then turn into GHA again. I started just scrubbing them instead and eventually they stopped growing GHA. I assume because something else took the shell over. 🤷
Did they grow coralline instead?

I think you will have algae issues until the tank gets more life in it and the rock gets more mature. It can take a long time to get past GHA

This is one of a number of things in this hobby that gets discouraging. I waited 8 months before adding my first fish not my plan but the vendor took 5.5 months to get my order to me. First coral was in the tank at 10 months so the lights were on 10% or less for 10 months while the tank matured.

Then I watch a Parker's Reef video showcasing a fully mature tank at 5 months.

 
I haven't watched the whole video yet, but you have to remember 2 things.

1 - It's just a video and a single point in time, you don't know what problems he may have had or will have. Even experts like Sanjay and Mike Paletta have problem tanks.

2 - Many tanks are often started with some stuff from their previous successful tanks, which makes things go smoother. I fully anticipate if I updated to a Frag 105.4 it would go rather smooth because I would use stuff from my current build to start the tank.

Not saying this guy won't continue to be a success, but anyone can throw a bunch of stuff in a tank and it will look awesome, that doesn't mean it will stay that way. This is what I dislike about social media, people often get a false impression that things are hunky dory, when in reality we have no context for anything. Example, someone posts a picture of their family all smiling on vacation, when in reality the kids are being awful, mom and dad fighting, it's rained for 3 days etc. Lol. But looking at that picture you think everything is awesome.

At least my Nitrate has not bottomed out lately

Membrane testing continues to show no added value to me using the Spectrapure membrane. Production is higher but it should be it is a 90 gpd membrane compared to the 50 gpd from Filmtec.

Wow!! I like the way you do things! I am totally stealing the information you end up gathering and using for my own RODI system as this is important and I simply dont have the time or interest in doing it. Thank you @KStatefan !!

I started this when I saw that Dupont had updated a number of their membranes and when their spec showed stabilized rejection of 99% and I was under 97% with my spectrapure.

I use their Membranes but am not smart enough to notice those things.

I need to pay more attention to bigger picture graphs. I must have something not working on my fresh air pump. PH had been trending down until we opened up the windows and were gone on vacation for a week. I am going to add a flow meter to the air line so I can see that. I did have some issues with salt creep build up in the venturi when the air was dry but I now pump rodi thru the line twice a day to keep it clean.

Still find it interesting how the probes go crazy when I am siphoning algae into a filter sock. I some understand the drop because my full siphon drain becomes unstable when I am doing that what I do not understand is the slow climb back to normal. I do wish that the scale usde on the graphs was like that all the time. I think the graphs can show way to much detail and make people think something is unstable when it is not.

My hammers all continue to look good and the one goni that has survived. The candycane that had been struggling looks good now. The only zoa that looks good is the Mandrin all the others have algae issues and are not open or barely open.

Maybe just particles in the water and the reading returns to normal at they dissipate.

I am so sorry @KStatefan I cant recall off the top of my head, you rune a Reefpi correct?

Those graphes are so much nicer than the APEX ones.

The water seems to clear up after a couple hours but the reading takes much longer. I know it does not matter but I am an engineer so these things intrigue me.

I test salinity every weekend with my hydrometer just to make sure everything it correct. I have been very happy with the auto water change system. I am changing 1.4 gallons per day spread out throughout the day. I started on July 19 and since then my salinity has ranged from 1.0256 - 1.0263. I plan on adding a third pump this weekend to start running that thru the coral QT tank.
