New tank Swords getting brown

Hi All

New to planted aquariums and I have listed my 'situation' below - anyone help shed some light on this?

- Tank - 190 litre Juwel Trigon

- 18w T8 x2 lights 960 lumens/ 6500 Kelvin

- Planted Amazon Sword (echinodorus bleheri) on Thursday into tetra plant complete.

- Added de-chlorination/water conditioner next day

- Its a new tank

- Temperature was cranked up to 32C

- I've only just started cycling this morning by adding ammonia and small amount of fish food


MY Theory

Temp too high/ no Ammonia was in there over the weekend. No nutrients, possibly lights not bright enough? (but I think Swords are ok with low level lighting?)...am I on the right lines?

Too hot, and the chlorinated water didn't help at all.
You want the temp around 25C.

Nutrient deficiency wouldn't kick in that fast.

Alot of plants are grown immersed and melt back when first submerged. They will die off a bit then grow new submerged foliage. As swords are heavy root feeders getting some root tabs in under them is a good idea.

Increasing the light will add to your problems. 32C is way too hot.

Fraternity of dirt no. 60.

Got a tank? Doing it filterless? Add it here!

shoot, cheers all.

So I will dial down the temp further and add some tabs

Will the tabs affect my cycling?

Should I trim back them brown leaves now or leave them to see if they recover?

cheers All

Leaves never "recover". After they've partially died, its only downhill from there. Cut off the brown ones as close to the base as possible. Trimming dead/dying leaves only encourages more growth. Be patient with newly acquired plants, they take time to acclimate.

Wait until the leaf is "well dead" before pruning. It won't hurt anything to leave the leaf on there for a bit. Plants will recover some nutrients from dying leaves before they are done. It takes a little while for swords to settle in after being moved, so don't move it around for a couple of months at a minimum and don't mess around the roots (don't gravel vac around them).

The post about plants being grown emersed (out of water) and losing leaves when immersed is spot-on. They will lose leaves also when light levels are dropped to a lower level if they've been growing at very high light levels.

The root tabs won't impact the cycling.
