What will green water lead to?

[seihakou]

Good day to all,

I have been experiencing green water 3 days after water change. Wondering what is the cause and what will it lead to.

Light hours 8-10 35 watt around 3 watt per gallon

New aqua soil 6 liters

Tank is 60x23x28

No co2

Dosing step1 1 pump daily / brightly k 1 pump daily

OF 8000 1 ml after water change.

Green water is usually due to too much excess light and excess nutrients and not enough plants to use them up, then green water becomes the dominant algae and blooms.

It usually occurs in outdoor ponds which are under direct sunlight, but can also occur in aquariums with bright lights (or exposure to sunlight) and lots of excess nutrients.

The green water itself doesn't directly harm livestock in a tank, but it can block out light from other plants in the tank and just looks unsightly. On the otherhand, green water is great for growing fish fry and algae eaters or filter feeders (its like they are literally swimming in food).

You can get rid of green water by reducing the light intensity and photoperiod, do more water changes to reduce the excess nutrients, plant alot more fast growing plants (fill up the entire tank with plants, not just a few sparse patches)... once the plants grow well and are able to efficiently outcompete algae, the green water will gradually disappear and it'll naturally stay clear.

The other alternative is to use a UV sterilizer to process and kill the suspended green water algae, this will work quickly but if the original causes are not solved (ie. excess light/nutrients, not enough plants), the green water issue will still always be present and you'll end up being over reliant on having to use the UV sterilizer all the time.

Is the tank too little plant in my tank?

With regard to dosing should i spread to alternative days between step 1 and k?

Yeah, thats very few plants and none are the fast growing types... if you want to balance the tank, you'll need to reduce the photoperiod or else the lights are just shining on empty space and feeding algae instead.

If possible, try planting more hairgrass and add as many fast growing stem plants as possible in the empty spaces to help soak up the excess light and nutrients. Later after the hairgrass grows more densely into a carpet and the tank parameters stabilize, you can gradually remove those stem plants.

Here is an example of what i mean by dense initial planting with fast growing plants: http://www.aquaticquotient.com/forum...rden-quot-Tank!

You can carry on dosing the ADA Step 1 and Brightly K, those are mainly trace/micro ferts and potassium, which don't contribute much to algae issues, its actually better to maintain the recommended dosing regimen of those ferts to support overall plant growth.

The white filaments on the hairgrass are a form of diatom algae, very common during the initial cycling period of new tanks, you can manually remove them with tweezers... or just leave them alone and they will usually disappear after some time, or if you introduce shrimps later after the tank is cycled, they will eat it up too.

Thank you UA, your replies are always comforting.
