I have no idea why my water turns a cloudy green after about 5 days from wc?

Is this usually too much sunlight?

No, the algae that turn water green grow perfectly well in ambient indoor light. If this has been going on long-term, you have a microbial ecosystem in your tank in which green algae out-compete filter microbes for ammonia.  Your fish can thrive in this system, but it doesn't look very good.

Do you aerate your tank?  

 

Since the tank starts to turn green a few days before your water change, you might consider doing two changes a week.

 

Tell us more about your lighting.  You mentioned sunlight.  Do you also have aquarium lighting?  What kind, and what photo period?

 

How often do you clean your filter?

Hmm I don't aerate separate to the filter water movement.

I have led lighting on the tank each side has 10white, 2red and 3 blue lights.

Sorry, no idea about photo period. The lights are on for 6-8 hrs day.

I changed the filter probably a month ago to the canister because I thought that may have been the issue (using media from other filter) but hasn't made a difference. At the last water change I put a medium and fine pond foam in to see if that works, too early to tell...

I would probably rinse the filter with tank water ever 2-3 weeks.

I hope this is the info you needed

Thanks so much for helping!

The  photoperiod is how long you have lights on, so you gave it to me   :)

 

Just a few more questions.

 

Do you have a substrate?  If so, what kind and how deep?

 

Are you growing plants in your aquarium?  If so do you fertilize?

 

To grow, algae need light, carbon dioxide (during the day), and ammonia or nitrate.  They compete with filter microbes and plants for their needs.  The more gas exchange you have, the less happy the algae, since they want to use all the carbon dioxide produced by the fish for photosynthesis.  So you might add more aeration.

Thanks, I have a sprinkling of gravel on the bottom and two Java ferns and an Anubis on rocks

I might need to add the bubble curtain I've got, the surface area of the tank is not huge

The water has started to look green today

From that picture, it looks like you have a tall tank.  I hope you have plans to upgrade to a larger, shallower, tank since your little fish will outgrow this one.  Gas exchange only occurs when water contacts air.  A bubble wall serves to "drag" water from the bottom of the tank to the top where it exchanges gases with the air before it goes to the bottom as more water comes up with the bubbles.

 

Do you allow algae to grow on the walls of the tank or do you clean it all off?

I most defiantly will be upgrading! Hubby put his foot down and won't allow a larger tank till we move to our new house next year. If it's longer than another 6 months I will word him up again or transfer to a large tub that is "easy" to move. The dilemmas of marriage...

Any how I have put the aerator in:

The fish love it! I feel bad, have I been starving them of oxygen!!

Do you think this is why the water has been going green?

At first I was wiping all sides of algae, but have not done this for a couple of months now. I do the front and sides if it is bad, but have not done so since changing the filter over to keep as many BB as possible

I forgot to say last time that I don't use any fertiliser for the plants just the equilibrium to adjust GH????

The fish are fine, but algae don't like oxygen during the day and nitrifiers in the filter love it.  So more air might help tip the balance away from the algae.  The algae that grow on the tank sides also compete with the green water algae, so you want them.

Ok thank you so much! I'll see how this added aeration goes????

The water still went greenish, but not as much????. I've just done about a 90% wc today so I'm hoping this will add to the good results and continue to get better????. Btw Blacky is not floating after eating now, does that mean she just need more oxygen to digest her food??

I don't think so, but anything is possible.
