Hi,
My name is Nicolas Munro and I live in Brisbane Australia. I've been
floating around a couple of aquarium news groups for a while now
looking for ways to get my plants to grow better.
Question is - What should I change or buy or do to make my plants grow
better?
My tank as it stands at the moment is:
192w Fluro lighting (2x 4ft on during day + 3x 3ft on for a couple of
hours each night and all day Saturday and Sunday)
300 L (90g) tropical freshwater tank
No CO2 - this is one thing I'm interested in starting not sure
weather yeast method is sufficient for my tank.
12 Tiger Barbs,
5 Silver Sharks,
Lots of Guppies,
8 guppies fry,
2 Sword Tails,
2 Mollies (they are great for eating algae/mold),
1 Cory Dory (kinda sick at the moment),
1 Bristle Nose,
-used to have a Yabby (Australian fresh water crayfish) but it escaped,
hid in my bedroom wall robe at the other end of the house and then got
mistaken for a cockroach and was squished.
3 crypts, 2x elodea.
The crypts are doing wonderfully but the elodea is sickly and can't
decide if it wants to turn yellow and melt or grow.
Currently I run my air stones from 8pm evening till 7am morning. I run
an air curtain 24/7 and have my 1200 L/H filter run when the air stones
are not.
400w heater
I add Seachem Flourish and last weekend i brought Seachem Flourish
Iron.
I have just recently stopped adding ph Down cause some one said it
added phosphates to the water.
Ph usually 7
Ammonia 0 to 0.1
Nitrite 0 to 0.1
GH/KH can't remember think ones 14 and the other is 10 but according
to the test kit is moderately hard but ok.
Temp 22 to 24 degrees C
Feed the fish more than they really need.
Water change between 20% and 50% weekly depending on my mood and how
much stuff I siphon off the bottom of the tank.
-------------------------
There are some species of Elodea/Egeria that are coldwater plants and
will not thrive in a typical fishtank. You probably have one of those.
If your crypts are doing well, you're doing the right things. Flourish
and Flourish Iron are good fertilizers and you have plenty of light.
Adding C02 is a great idea, or you can use Flourish Excel. I used to
use two 2l soda bottles of sugar and yeast for a 55 gallon tank, so it
will take quite a few bottles of yeast for your 300l.
I think all you really need to do is add a lot more plants. They seem
to grow better when you have a lot in the tank, and you will have much
less trouble with algae. Plan on planting at least 50% of the
substrate. 70% will give you that lush, jungle look. Some of my
favorite easy plants are Anubias spp., Crypts - there are lots of
interesting species, swordplants, bunch plants like Hygrophila spp.,
Ludwigia, or Rotala indica (or rotundifolia), or grasses like Sagittaria
subulata. I don't know which of those you can get in Australia.
Your tiger barbs may nibble at the plants, but with enough plants, it
shouldn't be too much of a problem. You'll want to avoid the yabbies -
they think planted tanks are salad bars.
