Hi, I have a high tech planted 30g that's been up and running for about 9 months now. There are a few issues I'm having with different things. I have the lower leaves of several species of my plants falling off, pinholes in several different plants leaves, I recently started having nitrate spikes in the last couple weeks or so since I changed some of the livestock.

I'll start off with my tank specs.

Parameters right before/immediatly after my water change today, second day after last water change:

KH: 6/5
GH: 4/4
Nitrate: 30ppm/5-10ppm
Nitrite: 0/0 consistently
Ammonia: 0/0 consistently
Ph: 7.2-7.4 consistently with co2 running at the lower setting I use at night. Immediately after water change its 7.6.

TDS: 250/175

Tap water is well water and has no clorine, I don't use prime, but I had an old bottle of stresszyme that I've started dosing over the past week because I said well, it's worth a try with the spikes and had it lying around for a couple years.


GH: 4
KH: 4
No ammonia nitrate or nitrite
PH: 7.8
TDS: 100

Lighting: finnex planted + 24/7 30" max setting 8h a day. Which a few days ago I backed down due to minor algae.

Filtration: 265gph canister, 300gph HOB filter

Ferts: EI dosing KNO3, KH2PO4, K3PO4, and seachem flourish. Alternating days micro and macro. I use excel on occasion if algae blooms come back.

Co2: 5lb canister, and an atomic inline diffuser. Co2 levels consistently brought to light green on drop checker from blue so I assume I have sufficient co2. I keep a close eye on my fauna and did a lot of playing around and keep it just below the point where I see them showing signs of stress.

Substrate: CaribSea eco complete planted. 3-4inches.

The tank has ten guppies, ten neon tetras, and 20RCS (30 more on the way along with three vampire shrimp).

I recently in about the past two weeks started having nitrate spikes, I can't really figure out what are causing them. I don't know if maybe I have to many fish now, they all were added over a month or so span last added a month or so ago. I lost a couple rcs as a result. I've been have to do water changes every other day because nitrate hits 30-40 ppm by the end of the second day. I've been keeping my filters clean and pulling out any dead plant mater that I can on a daily basis.
If I were to be over dosing KNO3 could this cause nitrates to rise? Should I remove this from my dosing?

Also I've been noticing over the past month or so the lower leaves of ludwigia repens, cabomba, and myrio red falling off. Along with pinholes in the repens, Brazilian pennywort, and a couple of my Anubia leaves. I've been having this issue since I started this tank, and the plants out grow the dying and I constantly have to trim and throw away excess along with the bare stem lower sections. I've read about it being a K deficiency which is why I was dosing it in my macros. I have no idea if there's anything more I should be dosing, or could be deficient of. Or if I need to stop anything. Was curious if I should dose calcium maybe, especially with the shrimp. Also I noticed some stairs popping up that are in one of the pictures that came out of nowhere andI can't ID. Don't know if they could be a factor.

Also notice a kinda rusty hue take over my banana plants that I have no idea about. They aren't rotting or melting really. Curious why this may be happening.

Last thing I'm curious about is a white fuzz that seems to grow on some of the roots in the substrate, you can see it on the roots on the anachris in one of the pictures.

Any and all help is much appricated if you have any questions feel free to ask.

Thanks a bunch!

I'd also like to add that there are several plants in the tank that are doing just fine, such as creeping Charlie, Italian Val, amazon swords, Monte Carlo, java fern, and also the anubias do really well.

What kind of substrate is that and how often do you vacuum it?

Could it be a flow issue? Maybe try using your drop checked in different spots?
