Thats 1.2 drop...maybe back off a tad

Keep an eye out that it stays steady and fish are ok...if it does id say you are close to dialed in

I don't know if this is accurate or not. But I used the Hamza reef calculator in backwards steps. I input my stale water PH 7.33 then changed alkalinity until the calculated CO2 was 3.0 (std indoor co2?). I needed 2.3 alk for this. So my combined alk with other buffers is 2.3. I then used 2.3 with PH of tank water 6.15 and calculated CO2 of 44 ppm.

thoughts?

I'll turn down the CO2 a bit tomorrow. then see where I am at. I have a lot of pearling in the afternoon. I can even hear the canister filter pump hitting the air bubbles.

44 is probably ok if you have plenty of oxygenation going on at the surface...

Watch your livestock if they are ok. Alot of planted tank people run in the 40 range with no problems

it’s hard to get a good picture in the daytime with all the reflection. Overall the bba is thinner and has less coverage than last week. The gha is still growing strong. At least I can manually remove gha. The bba is impossible to remove.

Phosphate is down to 3.8. I’m going to bring it down further to 2-3. I’m leaving the lights alone this week. I adjusted the co2 down a bit. The bubble counter doesn’t have enough water in it so I couldn’t measure how much I reduced it. I’m setting out a cup of water today to find out.

day old tank water PH 7.10
tank water PH 6.11

Effective Alk dKH for PH 7.1 with CO2 at 3ppm = 1.3 dKH
CO2 of tank water at 6.11 PH assuming effective Alk at 1.3 dKH. = 28.5 ppm.

I'll keep the CO2 at this level.

Looks perfect. If fish are ok you are all good.

One caution...watch your dKh. Yours is low like mine tends to run. Great because you can grow any plant you wish but keep an eye on it. My tank slowly eats away at dKh(organic acids build up)
I base my water changes on that by watching my ph graphs. My water is about 2 dKh from the tap.
When it creeps down to 1.5dKh i do a water change. Sometimes its 5 or 6 days, sometimes 10, depends on plant growth rate.

Weekly update time. The gha was bit less this week. Bba was also down. Some leaves are clear now, most have bba on the edges, and a few are still fully covered.

i trimmed out as many of the bad leaves as I could. What’s interesting is my phosphate and nitrate are up this week despite dosing less My theory (Or is it hope) is the bba is dying and releasing stored nitrate and phosphate.

I am keeping things the same again this week.

May not hurt to slowly ramp lighting back up a little

Tank seems roughly the same as last week maybe better? I’m not sure. Phosphate is starting to come down again. I’ll add 2 hrs to the lights this week. I need to figure out how to photo the tank better reflections are bad.

Yes up the light and get those plants pearling! If everything is back in balance, the plants can outcompete the algae
