Flow causing odd growth?

My tank is a 10 gallon with 2x hob filters (Aquaclear 30 + 20) ... The 30 is dead center in the back and the 20 is on the side to catch some dead zones (due to my hardscape).

My rotala have been through a lot (getting to the point that they are now), but I am convinced these guys are suffering from too much flow --> really thinking of reducing the flow but wanted some feedback first.

I have miracle gro in the flourite substrate which keeps most of my nutrients in check except for potassium (which I dose as needed). There is co2 which was a recent addition (I just hit 4dkh + ph 6.6 = 30 ppm today ... had to slowly bring up my KH to allow for the swing). GH = 120 ... Ca:Mg about 6:1 ratio in hardness. My light is a nicrew RGB dimmed to 75% on a 7 hour photoperiod.

Aside: I have crushed coral in the back which I had to help with buffering from a while ago that leaches calcium -- also debating removing this now that I removed my almond leaf which leached acids ... I want the almond back for health benefits, but that is for later me to determine how to re-introduce it.


Below I have attached 3 views of the rotala (side/top/front) -- about 7 stems have made it straight-ish ... the rest just grow horizontal, throw off roots to stabilize, then attempt to shoot stems up.

Any thoughts?

Cheers,
Josh

Hi @dw1305,

I will attach 2 more photos from today: they are more pinky rather than pale (or perhaps some more adept eyes can weigh in here).

I have miracle gro (slow release) in the substrate that I am certain leaches into the water column (verified with phosphate test ... I keep my macros up and rarely dose the micros ... perhaps I should?).

Here is the composition of miracle gro:
Nitrogen = 9%
phosphate = 4%
Soluble Potash = 12%
Calcium = 3.5%
Magnesium = 1.4 %
Sulfur = 7%
Copper = 0.05 %
Iron = 0.9 %
Manganese = 0.35%
Zinc = 0.1%

Any thoughts on if there could be a deficiency present from these numbers?




Side note as per my other post https://www.ukaps.org/forum/threads/tds-immediate-dose.59274/page-2#post-580512 ... this may be contributing to my TDS reading.

Do you think that odd horizontal growth in those other pictures is due to flow or just deformities from previous deficiencies (which there were)?

Josh

Thanks Darrel!
@dw1305

To throw this down another path:

1) since I started co2 injection, I noticed a bit of glass algae forming and hair algae in my java moss which is close to the light. My though is the plants took longer to acclimate to the co2, giving the algae a chance to grow ... now I just have to put complete it by either planting more or waiting for my plant density to increase and manual removal until I win.

2) with regards to the previous post @jaypeecee in conjunction with the info here: will a nutrient soup causing that tds impact the livestock? The plants love it ... I think... or is it overkill?

3) if those tips of the plants look healthy (first time in my life so I’m thrilled), then do I just give it time and trim the older dead Ish ones that aren’t growing to make them grow into a beautiful bush?

cheers,
Josh

Interestingly, once I added the canister filter which was way over-sized, the growth went in the other direction (I had a typhoon).

I have since removed that and have a less gph hob far off-Center and the large hob on the edge away from the plants and flow being broken by hardscape.

The plants are growing straight now.

The amount of variables is crazy.

Cheers,
Josh
