Whaaat? 8O
I have a few fully Dutch tanks here and...
Plants DO NOT Looove ammonia!
They
can use a trace amounts, but a big spike will burn leaves!!
(which equals dead debris adding more ammonia and nitrite spikes)
Plants cannot allow you to just add a bunch of fish..(unless there is a not so mentioned high speed mechanical filtration device in the background of this picture)
Plants DO NOT loooove poop. They love pooop that is broken down by bacteria. Ever put fertilizer on plants direct on accident...remember what happed? The guy next door with layer of fertilizer on his now DEAD lawn?
Most fertilizers are broken down before sold. Not straight from the animal!
Plants also have a heavy requirement for Nitrous product. NitrAtes and then NitrItes. That means bacteria
You believe all that on plants..back it up with a Dutch tank..and we'll see how many fish can be supported!! Or how much work versus esthetic plants do for a contained aquactic enviroment. you cannot count the mega filter of nature and how it interacts.
By the way..parameters for Dutch 10 gallon #1
Ammonia0
NitrIte0
Nitrates 0...and may creep up to 0.07 before clean/change
Temp 78 kept slightly lower than other tanks to avoid the plants stealing water oxygen instead of adding it.
pH raised from tap 7.0 to a 7.4 then droppeed slowly to 6.8 during first week. Water changes go from 7.0 to 6.8 now. It is tested 3 times a week.
And no green algae, but the silicates left by most plants makes diatomous algae start to develop if you are not ridgid in cleaning schedule.
Plants can do nothing for Pre-Cycling at all. And the wrong plants will wither and maybe die completley
(which takes your parameter into overload!).
You need to fiddle with lighting and their care. Most aquatic plants require the same pH as most tropical fish. Too soft or hard and its slimy vegetation city.
Plants are great and add to your fishes health by giving them a more natural enviroment. And they have other benefits..but you cant just throw a bunch of plants in and then load up on fish!!!
And I won't let it stand for a new aquarist to take literally without putting some burn into the painted sunny day. :?
I am newly reborn to the hobby and modern practices..
but I know how to keep Dutch tanks and I know my labyrinth fish well.
Even the Griggs fact you quoted say
A med-lg fish load... Even ghost shrimp and snails are considered bio load. But does he mean a med to large group of fish? (Or A as in single medium to large fish? You can do that anyway. With a nearly bare tank!) (and did you read his tips completely? Did you miss the addition of BioSpira?!)
And because it worked well a couple times for one-two people doesn't mean it should be a common practice.
No more than tropical fish in a cup!
edit:
PS 10gal Dutch #2 is having the parameters waver becuase some of the fish are approaching adult size. They are being moved next wekend.
edit: spellcheck misses em!
