Whats best for growth.

I have a fully functioning discus setup that has been running for 2 years, however due to high discus temps, plants normally turn to mush. Have reordered a lot of plants that are meant to be ideal for discus temps;

Hygro Polysperma
Java fern
Amazon swords
Cyrpt becketti / wendetti
Giant Vallis

I dint want to remove gravel to put laterite / soil down so was wondering if i could 'pot' the plants using laterite as their substrate with a layer of gravel to prevent contamination of water? If any links could you please post them? What substrate is best for plant growth?

Setup / equipment is as follows

Juwel Rio 400 (60" x 18" x 24"high) - 400 litres
Eheim 2329 wet / dry external filter
Ehiem 2018 external filter
Arcadia I-Bar T5 lighting - 2 x 54w bulbs
JBL profi 3 CO2 setup inc ph controller, pressurized bottle. solenoid etc

W/C 2 x 100 litres per week.

8 x 6" discus
3 x cory julii
2 x Ram cichlids
4 x apisto cacatuoides
2 x golden nugget plecs (L177)
30 cardinal tetras

Cheers guys!

Ahh..... the reason your plants are turning to mush is most likely your crappy lighting. You would need at least double what you have to keep most of those plants growing.

You can pot most of those plants. Java Fern can be tied to rocks or wood.

I would not use laterite in pots. Instead I would use something like Flourite or Eco-Complete.

Yeah, 4x54 T5 (48 inch) will get you there, with the last foot essentially unlighted. In the USA, there are 80 watt T5s which are for 5 foot tanks. No fixtures that I know of, but there are 60" bulbs,reflectors, ballasts, and endcaps etc for DIY enclosures. Very efficient. Three of those would give you a decent amount of light. Four would grow the most demanding reds, assuming you have parabolic reflectors on each tube. BTW, Ariweiger's thread shows potted plants. Link below.

Three Tanks...Eheim 2128 & XP3-90G, Eheim 2128-65G, Eheim 2232-25G.... Tek 4x54 watt T5-90G, Aqualight 96watt PC 65G low tech, 65 watt Aqualight-25G.... Hydors-90G & 65G ... Flourite in 90, 65, & 25 Gallons, .... Auto Water Change/Auto dosing on 90 & 65 gallon..... AGA member......

I was thinking of putting my original juwel T8 light back on the tank along with the T5 light - so i will have 2 x 54w + 2 x 39w lights? Otherwise can anyonento the suggest a way of moutning interpet powercompact T5 lights into the tank WITHOUT modifying the hood?

Cheers for all replies.

I have now added the original juwel balalst back into the tankn (2 x 48" 39w tubes) - so the wattage is now 182w rather then 104w - i have also added reflectors and i immeadiatly noticed the difference, the light seems much more intense and directed if you now what i mean. Also what t8 lights do you reccomend for plant growth?

Since it is obvious price isn't a huge deal for you I suggest a couple metal halide pendants for your tank.

In college....so no aquariums for a while.....
