Is my C02 Good?

So my 75 gallon is starting to look pretty good, I'm dosing EI and injecting a TON of c02. Temperature is 76F, Kh-2, Gh-4, and lights are on for 8 hrs. Here is my ph/c02 profile

C02 comes on 4 hrs before lights on ph is 7.22
Lights on at 2:30pm ph is 6.38
3:30pm ph 6.32
4:30pm ph 6.30
5:30pm ph 6.35
6:30pm ph 6.38
7:30pm ph 6.31
8:30pm ph 6.36
9:30pm ph 6.36 c02 shuts off
10:30pm ph 6.38 lights out
I think I'm heading in the right direction but wondered what the pro's think?

Iím not a pro, but Iíd say if you arenít having algae issues, your plants look great (they really do), and everything is healthy and growing, youíve got it right.

Your plants look awesome. Sometimes getting that 1.0 pH drop is not possible. But best way to assess anything is by looking at the plants. As long as u have healthy plants then u must be doing it right. In other words don't fix what ain't broken.
How long has the tank been set up? Wats the substrate? And how r u dosing ferts? Just curious to know.

Hi I started a five week dry start with ADA Amazonia substrate, to give the plants a head start and grow a healthy root system. It has been flooded for about four weeks now and the plants are growing well, so 9 weeks so far. I have been dosing the EI method by Tom Barr. Originally I had the lights ( Fluval 3.0) set at one hour sunrise, 6 hours at 85%, then one hour sunset. I started to get hair algae on the top of the rocks closest to the light so I have dropped the lighting down to 70% to see if it helps, and ordered 10 ammano and 10 Red Cherry shrimp.

Cheers!...Peter

Nice looking tank. Healthy looking plants and well presented.

As you probably know, with more light you will get more color out of some of those plants.

But that can also cause other issues, so I guess if it ain't broke don't fix it.

Well done.

Hi Greggz, thanks for the kind words I really appreciate the feedback!. I originally had the light intensity much higher but got into some string algae on the rocks and a couple of plants, so I turned the intensity down to 70%. Will observe it for a while and see

Cheers!...Peter

What light do you have? Thanks.

EDIT: Nevermind, you have the Fluval 3.0. I was thinking of switching that myself from the original Finnex Planted+ 24/7.

It's a 48" inch Fluval 3.0 more than enough to grow plants
