Re: [Aroid-l] Aquatic aroids

From: REDRAGON40 at aol.com on 2009.09.24 at 15:37:02 Steve: You may want to check carefully which Amazon swordplant you get. It depends on whether you want it to grow out of the water and how big you want it to get.  The final size is important to know ahead of time because swordplant (Echinodorus spp.) roots are invasive to say the least, and removing it later might be problematic.  I had one that I put in a tub outdoors that was almost two feet deep and the swordplant put out emersed growth two feet above that.  They are heavy iron feeders and grow like crazy in conditions they like.  Swordplants actually prefer to grow emersed and one of the appropriate size would be magnificent.  There are also varieties with different amounts of reddish coloring which could possibly harmonize with your  aroids better than the bright brittle green of some of the ones most commonly seen in the pet shops.  You might also consider some of the really small types as companions to the other plants you have at the "rivers edge"   Carol Ross, Bucks County Aquarium Society   < ' )))><   In a message dated 9/24/2009 1:18:11 A.M.

If you check the link I gave you'll see that Devin has created some really neat planting devices that allow you to suction cup the pots to the back of the aquarium.  If the plants will tolerate the water you can plant them lower and if not just place them higher on the back wall.  He suggests using sand or gravel to create the bottom of river and you just keep the larger rocks turned to keep the algae down.  Rocks and driftwood are used to hide the planters which are neatly devised.  Devin displayed these at the IAS show and I think he has a hit on his hands.  I'm about to set up a 55 gallon aquarium using his products and since he is on Aroid l I'm sure he'll answer any of your questions. His design allows us to simulate a river's edge with aroids appearing to grow terrestrially along the river bank but plants such as /Spathiphyllum/ can be grown in the water or at least partially wet.  In my case I'm going to plant small /Philodendron/ and other aroids on the "river bank" using Devin's pots and the put large rocks and gravel in the bottom.   I plan to use a larger rocks and rocks along with driftwood to hide the pots.  I'll use the driftwood for the plants to climb on and a large Amazon sword which can be bought at almost any aquarium store as the underwater centerpiece.  For fish I'm going to stick with around 12 neon tetras. The plants will be the actual display and the fish are only to allow movement and life. If the bio load is low the build up of nitrates is minimal and algae stays low. Anyone that tries this needs to keep the bio load low or you'll have a build up of nitrates.  However, in this case those nitrates will be used by any plant with roots in the water.  Having kept living coral reefs for many years I've learned that if you simply put an undergravel filter beneath the rocks and gravel you'll create an anoxic zone which also helps to lower the nitrate build up.  Just don't hook the undergravel filter up!  The tank will also need a filter but external filters work fine for this purpose. For light I'm having a hi intensity aquarium light hung from the ceiling which will keep the plants healthy. Here's the link again: http://hydrophytesblog.com/wp-content/uploads/2009/09/10-ix-09-tank-i-b.jpg I'd suggest you go through all Devin's links and look at this photos and read his explanation.  The concept is really simple and neat.   Having kept large aquariums for 50 years I think this one will be spectacular.  I plan to talk to Tom and see what aroids might tolerate the water so I can have a larger choice of plants for the background. Many philos are rooted in water so should do well and some Anthurium species may do well if not drowned. Forgive me if this is full of typos!  My desktop is in the shop for a tuneup and I'm trying to type on a laptop with tiny keys!!! Here's another photo Devin sent today of a tank of /Spathiphyllum/.  Tom told me a few months ago these plants are "water hogs".
