Planted Tank Problem

Hi All

I join the forum recently.

I am trying to set-up a planted aquarium, but having problem.

Sep-up. I started with; 3ft x 1.5ft tank approx. capacity 30 gallons, Ehiem 2224 canister filter and 3 florescence tube lights 30 inches long each.

I spread Tetraplant “CompleteSubstrate” about 11.6kg creating a layer of 3 cm and spread 2.5 cm layer of gravel. Half fill the tank with water.

The filtration and oxygen bubbles were going for 4 weeks before I introduce plants (Eleocharis parvula) and DIY CO2.

Now, after 8 weeks their are small sign of new grass, but gravel has big brown patches like cobwebs. I have clean and changed water a few times but brown patches reappear. I leave the light on for 8-10 hours.

Thank you all in anticipation.

regards

What types of florescent tubes to you have? T5, T8, etc...
Too much light can induce algae that'll cover up the plants.

Plants depend on Lights, Nutrients, and a Carbon source usually CO2 to thrive.

If you can, check out our plant guide which will explain everything

Hi, Does anybody know if it's a good idea to take out top layer of gravel and just leave 3 cm of Substrate.
Thanks

You already have a good substrate thickness, so there is no reason to reduce it. If you have adequate lighting, proper temperature, and some nutrients, the plants should grow.

Thank Hoppy.
Well, that was expected. But after 6 weeks the tanks is covered with brown patches. I must be doing something wrong. At the moment their are no fish. Because I want to get a stunning looking tank! First

I must say, I could not get the small gravel so I used the cheap gravel.

The idea is to have a carpeted (Eleocharis parvula) aquarium with Neon tetras and shrimps, eventually.

In order to get it right and speed up the process, I am considering using FERTILIZER. Any suggestions!

If you don't have any fish, I would dose some excel at somewhat high dosages to see if that helps get rid of it. Also, definitely reduce the lighting. How high above the tank are the lights?

Hi josh,

I assume "Excel" is kind of FERTILIZER.
It's a standard 3 ft tank and the lights are attached to the hood.

I will keep you posted with the progress of the tank, by the way, I have also introduce Rowa in the filter to reduce alge (brown Alge).

Excel is intended to be a way to get extra carbon to plants without injecting CO2, however, most of us use it primarily to kill algae.

Plants also need Nitrogen, Potassium, Phosphorous, and trace elements, more or less in that order. If you have 3 T5 bulbs (HO or normal output?) you likely have pretty high light, and the plants will need significant nutrients to meet their growth rate requirements. I would read the dosing sticky in the fertilizer section to get a better idea of what is required. Ordering dry ferts from aquariumfertilizers.com and root tabs online from RootMedic is much more economical than trying to get what you need locally. You can also buy all the chemicals you need in bulk, but you'll end up with more than you would need to run 50 aquariums for 10 years.

Where are my manners? Welcome to the forum.

Hi All,

Any idea what would be the best Substrate, to go on top of “CompleteSubstrate” by Tetraplant, I am considering Amazonia by ADA. But it is a bit expensive.

Sharkfood thank you for supplying on-line shop names, but I am based in South of London.

By the way, as i said above I am trying to have a carpet of Eleocharis parvula.

Thank you
Regards
Zeberi

Sorry man. I didn't look to see where you were located. Shipping chemicals overseas is problematic at best. On the upside you can order Tropica plants.

Try checking out ukaps.org maybe. I'm sure someone there can tell you where to get ferts in the UK.
