Potting Amazon Swords For A Goldfish Tank

A Need For More
The goldfish tank was looking pretty lack luster. The only plants inhabiting the tank were java fern attached to driftwood. It looked nice, but the tank was missing some variety, and some tall plants to fill the upper portions of the tank. Julie and I decided the tank could use some sprucing up and we decided on amazon swords, since I had a plethora of them coming from a mother sword in my tropical planted aquarium. The next step was to figure out how to get them in there adequately.

Pot Them!
Our goldfish tank does not have a suitable substrate for plants, it has large river rocks in the bottom. This was a problem. Amazon swords need to have a good substrate to send their large root systems into, to secure them down and to get nutrients. A need fueled an idea . . . Pot Them! We headed out and got three 3" clay pots, making sure they had not been treated with anything. I rinsed them several times in hot water to make sure there wasn't any residue on them that would adversly affect our beloved goldfish. Then I set to work.

Potting The Swords

The first step was to get some gravel and put it in the bottom of the pots. I filled the pots about half way at first. Then went some Flourish Tabs I had left over and I nestled them into the gravel. I put one tab per pot. Next, another thin layer of gravel over the tabs. By the end of this the pots were almost 3/4 full of gravel.

Then I had to get some plants. We only needed 3, and I had many to choose from. Because we want these to be background plants, I wanted to find the 3 biggest and healthiest looking plantlets. First I cut the runner off of the mother sword and then inspected the plants and picked out the ones to use. I cut those off of the runner. Once they were cut off I trimmed any damaged roots and then wrapped the roots into a little ball to help keep them from getting damaged during the planting process. I then nestled them into the gravel in their prospective pots and filled the pots up the rest of the way with gravel, to hold the plants up. The end result was 3 nice looking amazon sword plantlets in some nice looking clay pots.

Once the swords get big, they will be repotted into larger pots. Now hopefully they will grow well provided the goldfish don't eat them!

Trying a new fertilization regime, Estimative Index

I am going to give the estimative index fertilization a try. I do not want to do such large weekly water changes though so my doses are going to be a bit lower than recommended. I am planning on weekly 30% water changes on my 60 gallon tank (so roughly 18-20 gallons a week). Estimative Index recommends 50% weekly water changes. I do not think my crypts will like that, and I just don't want to do that much.

Tank stats: 60 gallon heavily planted 110 watts PC and 64 watts of normal output (regular) fluorescent lighting (2.9 watts per gallon, but 1.8 of it is PC light) - 12 hours a day 3 Hagen yeast CO2 systems, changed every 3 weeks Substrate is 4-5 inch gravel bed with 60 grams of laterite

My fertilizer regime is going to go like this:

Sunday, Tuesday, Thursday : 1/4 tsp of KNO3, 1/16 tsp of KH2PO4, 1 capful flourish excel

Monday, Wednesday, Friday : 1/16tsp of trace elements (CSM+B Plantex), 1 capful flourish excel

Sunday am : 18-20 gallon water change, 1/4 tsp GH booster (has Potassium Sulfate, Calcium Sulfate and Magnesium Sulfate). Start over with dosing regime.

Every 3 months : 3 flourish tabs (at the base of swords and crypts)

I just purchased my fertilizers from www.aquariumfertilizer.com, so I will be starting once they get here. I may find I need to up my doses a bit, but we shall see how this goes. I am concerned I may need to add extra iron, but again we will see. If it is needed I will probably just use Flourish Iron and start at 1/3 the dose they recommend since the trace elements should have some iron in it. I may also find I do not need the GH booster. I plan to test my GH weekly for awhile and see what it does. This should be an interesting experiment.
