CO2 and Cryptocorynes

Cryptocoryne X Purpurea Ridley Nothovar. Purpurea ‘Kota Tingga’

This is by far probably the rarest Cryptocoryne I own, especially considering they have completely destroyed it’s natural habitat due to palm oil plantations being put up.  I really hope I can grow this one and propagate it so it can be spread to fellow hobbyists; here is a link for further information and pictures of the plant :

Since I literally just got this plant it still needs to adjust to it’s new conditions, I’ll be keeping it in my emersed tank like many other Cryptocoryne’s I own.

Lighting- Coralife T5NO Dual Bulb – 6700k and rosette bulb – Lights are on for 10 hours. 
PH- 7.5
Substrate- Homemade substrate mix, cow manure, sheep manure, worm castings, natural red clay, and cheap topsoil.

Cryptocoryne Cordata Var. Siamensis ‘Thailand Sungai Kolok CTSK’

There is little to no information on this Cryptocoryne anywhere on the internet; I can only trace it back to two people, one in which I know personally and is a great friend of mine; where the other one who originally brought this plant in hasn’t said much about it (at least from what I could find).

I just recently got this species on the weekend so it is still adapting to it’s new conditions and is quite small; however as it grows I will take lots of pictures.

Also, here is a link to my friend who posted a picture of the spathe when he had it blooming: Photo belongs to orchidnutz;Jim. R

Right now I have it under the following conditions:

Lighting- Coralife T5NO Dual Bulb – 6700k and rosette bulb – Lights are on for 10 hours. 
PH- 7.5
Substrate- Homemade substrate mix, cow manure, sheep manure, worm castings, natural red clay, and cheap topsoil.

Cryptocoryne Cordata Var. Siamensis ‘Blassii’

Cryptocoryne Cordata Var. Siamensis ‘Blassii’ is another plant that gave me trouble submersed, however in emersed conditions this plant grows extremely well and sends many daughter plants.

This is a great beginner Cryptocoryne that you don’t always see for sale; I originally got this species from Oriental Aquarium in Singapore.

Lighting- Coralife T5NO Dual Bulb – 6700k and rosette bulb – Lights are on for 10 hours. 
PH- 7.5
Substrate- Homemade substrate mix, cow manure, sheep manure, worm castings, natural red clay, and cheap topsoil.

In some pictures you can see the pink “shine” the plant has, it’s quite attractive.

Cryptocoryne Crispatula Var Tonkinensis

Cryptocoryne Crispatula Var. Tonkinensis is a rather difficult Cryptocoryne to grow since not much is known about it’s location or it’s cultivation aside from it’s exporter Oriental Aquariums. Whether they are being supplied by someone else or in fact growing this plant themselves no information has been released in terms of it’s preferred conditions.

I’ve had a difficult time keeping this species alive since I cannot find much about it but it is a rather odd looking Cryptocoryne when you compare it to all the other species. It has extremely thin leaf blades and has reached heights of 16 inches in length for me when it was flourishing, although it is now much smaller yet still hanging on at around 6-8 inches tall.

I’ve seen zero runners or any signs or a runner in the entire year that I’ve had this plant which is rather depressing, but once I crack this code I’m sure I will have it flourishing.

Here are the conditions I am currently keeping the plant in:

PH- 7.4 at night, 6.5 during the day when CO2 is on.
Temperature- 74-76
Lighting- 30″ Dual bulb T5HO – 6700k and Rosette bulb (7 hours per day). 24″ Dual bulb T5HO – 6700k and Rosette bulb (2 hours per day during the middle of the 7 hour lighting period)
Filtration- Marineland C220 Canister Filter
Substrate- Flourite Dark, Flourite Red, Flourite Black Sand, Muriate of Potash, Dolomite, Mineralized Top Soil, and Natural red clay from the earth.
Water Changes- X 1 a week
Dosing- Alternate Micro and Macro ( 1 day Micro, 1 Day Macro, etc)

If anyone has had success in cultivating this species please comment and let me know how you are keeping it.
