Hi guys quick question about some plants.
I got some plants last week Echinodorus grisebachii 'Bleherae'
Echinodorus Dschungelstar Python
Echinodorus grisebachii 'Tropica'

The Leafs of the Echinodorus grisebachii 'Tropica' are yellowing and becoming transparent
What's going wrong! is it Iron
Also I hear it's normal for plants to die off and regrow new leafs later!

Any help is appreciate
Thanks
Obliged
Paul

Tubes are gone Paul...

Flourescent tubes should be replaced every nine months...

You should consider LED retro fit tubes...They last for 3 to 5 years (50,000 hours apparently) and use about a fifth of the electricity...Initial cost is dearer but well worth it in the long run...

Heres an example...Forget what you have heard about watts per litre....For plant growth the magic number is 6500Kelvin...Anything between 6000 and 8500 will grow most plants pretty well...

Oh and if you create small waves at your water surface when using LED lights you get whats known as the shimmer effect....Your water will sparkle...Its beautiful to see on a sunny day when theres lots of natural sunlight coming in along with the LEDs in full colour...

Also just be aware that Juwel tubes are a slightly different length to all the other bog standard ones as far as i know....

Juwel are feckers for making everything awkward to modify...Marketing crap...They just want you to buy all their stuff when it comes to modifying Juwel tanks in any way...
