Just an update:
Wow... Just wow...
The switch from PPI to EI has made the plants grow quite a bit faster and fuller, there is a lot more pearling of O2 to the point it streams to the surface. Things are finally turning redder - Still haven't mastered that yet
I had a couple of friends who don't own aquaria tell me the tank looks so much more lush than it's ever looked. They asked me what I did.
The switch to EI wasn't without bumps. There was a moment I had spot algae and string algae reappear after they hadn't appeared in months. A slight adjustment to light and CO2 did away with both. I've watched small patches of BBA melt away.
Thanks for your advice. I'm staring at the tank as I write this, it's never looks so good.

Quick update and advice request.
EDIT: String algae, not hair
Today I noticed the beginning of string algae on some moss and one of plants. I have been dosing to EI up till now.
I raised CO2 when I started EI dosing - 2.5bps to 4bps.
My instinct made me raise the light 2" higher to reduce PAR till I figure out what's going on. In the past this did away with the hair algae and it didn't come back.
Any advice on how to proceed? Raise CO2? Reduce EI?

|HD Blazingwolf||U may not need it. Try not dosing and see if u get a deficiency|

|smiller||Whoops....that is my phosphate that is 5. I don't know my potassium reading.|

|smiller||I do not dose for GH, my levels are already high for that and for KH as I am in a very hard water area. Potassium level is usually around 5 per my calibrated test kit, but that is the reading I am getting from my previous fert dosing of KNO3 and KH2P04.|

|HD Blazingwolf||U may not even need k2s04 if u dose gh booster, and ur potassium levels in ur tap water are significant|

I did the calibration already and my kit is very close. I estimate my nitrates to be in the 40-50ppm range after a 50% water change and EI dose of KNO3 on Sunday. I know that 50 is really not a "dangerous" level but I thought maybe the K2SO4 (which I have never dosed before) was to use if your nitrates were at the level that mine are.

Before you do anything about the NO3 levels, make sure you check to make sure the test kit/method is correct to ebgin with.
Make a reference standard, then and only then..............do you decide whether to add/dose less KNO3 etc.

If there is an issue, I'll do 2-3x a week 70% etc.
But unless the CO2 is addressed correctly and carefully, you will keep suffering.
This has nothing to do with the fert dosing.
And we see nasty algae in every single type of fert dosing.
We also see good nice planted tanks as well. So this suggest that light/CO2 are the main issues, not ferts.

given enough time they generally make any form of nutrient available to plants
api test kits are fine if u calibrate them with known amounts.

I would like to jump in here, and not hijack the thread or anything, but this seems like a good place to ask this:
If my NO3 levels are at ~30 ppm daily without dosing, is it ok to assume that these organic sources are bioavailable to the plants? I have lots of fish and I tend to feed heavily, and when dosing EI according to Wet's calculator and others, I end up with way more NO3 than I would like at the week end WC. If I can trust API test kits, it's deep maroon.
Also, what's the thoughts on the best test kit for nitrates these days? Someone mentioned the Salifert kits. Are they still considered useable?

This is fun!
Cue side shoots appearing in the last week:

|plantbrain||More water changes often help a lot if the CO2 is poor also. As mentioned, watch for new side runners/shoots etc.|

Ur plants are hungry!!! and when they get what thye need they will grow
once u dose ei for abou 2 weeks plants will have absorbed and stored a fair amount of nutrients, they have "fat" cells much like we do
i'll take a stab and say that co2 usage has increased as well u may want to watch for signs of deficiency and algae in the next few weeks.. plants store carbon as well and it sounds like its getting used nicely
