Question Amazon swords unable to survive in my 50gal

It took me awhile to get to asking the question, since all 7 amazon swords have already melted away in my 50gal, but.... why?

It's a Seaclear System II 50gal. The current is very strong. Do swords melt under strong current?

It also seems like my dwarf sag is unwilling to spread into the areas where the current is stronger. They've spread into a dense, neat oval-shaped safe zone where the branches and rocks deter the current. LOL

Is it just me, or is this current-hating actually a thing?

Life is full of regrets. I wish I'd just gone the normal Takashi Amano route instead of this crazy Seaclear System II. It looks like nothing wants to survive in here except for moss.

Yeah the tanks been running for 2 and a half years, all specs are fine.

i had swords survive the onslaught of half a dozen ranchus with oversized cheeks and lips for years... these plants ought to be pretty hardy.

what are the temps? type of light?

I recently rehomed a massive sword in my forgotten planted tank which someone had gifted to me though it was 6x smaller back then

my tank ranged from 68-79 with slightly acidic water and 4 t5 plant bulbs in a 17g tank. Since it was formerly a reef tank, there's an overflow with a massive powerhead creating a ton of current in the tank. The stems never took off in this tank but the swords loved it.. I'm sure your tank must fall somewhere between these two tanks somehow.

Are you dosing anything? Swords are root feeders and appreciate nutrient rich substrate or root tabs along with good light.

I use eco-complete, though it's been sitting in there for 2 and a half years already. Maybe the nutrients have already drained out by now?

Temp is 72~78, depending on the season. I live in Southern California, so weather isn't much of an issue here.

Just one T5HO bulb.

pH is 8. Maybe pH is too high?

Eco complete doesn't have macro nutrients. Its a rather inert substrate.

Definitely your lack of substrate ferts. I've never tried amazon swords for years until just a couple months ago. My tank uses turface (like light colored Eco complete). It's just an inert fire blasted clay gravel with high cec. I use two HOT5 bulbs and my sword is growing like a monster. Dwarf sag as well. My ph is 8.3 as well. The main difference. I have an inch layer of super nutritious mud under the gravel feeding the roots.

Definitely pick up some root tabs for your root feeders. You'll notice the difference within a week or two

Ahh, thanks for the reply!
Definitely doing that... especially if my dwarf sag could spread too.
