Hair algae and unwanted weeds, Time for a clear out?
 
Hi all, had some filter trouble recently where I had to replace my filter, twice. During my breakdown of my internal it spat a lot of yuck into the tank, which seems to have cultivated into hair algae as it is exactly where the yuck landed on my plants.
My lights are on 12 hours a day, t5 tubes. I have tried to reduce the amount of time I have them on to 10 hours but didn't help.
I only have 2 types of plant in my tank, dwarf hairgrass and quite a few large amazon sword. It has populated my amazon sword first then my hairgrass.
First of all is the hair algae its like a grey black in real life.
Here are a few pictures

I need to get rid of them, and I am seriously considering ripping all my plants up and replacing them all I am getting that stressed over it :(
Next is some unwanted weeds that came in on a shipment of riccia, only a few appeared and now I have to net them at least twice a week they are so fast growing!

I AM SORRY THE PICS ARE SO BIG :(
Please help me sort out my tank, any sugestions or is it worth just ripping everything up?

hay :)
that stuff on the top is duck weed,and it really grows like its name weed !
if you want rid of that then you literally have to remove everyone of the plants,as they just
multiply if you leave any in there ,although any top dwelling fish will enjoy the cover.
as for the hair algae,i don't know,i have some my self on the swords,even though after
a severe cut back i thought i had got rid of it all,but it's there,and i too am not sure
how to get rid of it.

Thanks for the reply
the duck weed is a right pain, its ugly and sticks to my hands whenever I do any work in there! Removing every single plant is damn near impossible! lol

tell me about it,but i managed,i got a net and pretty much scooped it all down to one end
then scooped and flicked into a bucket,it took for ages,but i felt better for it,now i leave it in the pond.

12 hours of light a day is to much, even 10 on a freshwater tank can be excessive.

I understand my lights are on too long, but it is quite difficult I don't have a timer and clueless when it comes to setting one up and I am out at work 8am till 8pm.

perhaps someone on here can help with the timer,my tank has one built in,
although i've never actually used it,because i work from home.

The algae on the leaves may be Staghorn algae or beard algae. The stuff entwined around the substrate plants is likely the same thing. Regardless of what it is, the solution is the same. Reduce the light duration significantly. Whenever I have seen issues like this--and I do--organics are also involved.

You have very bright lighting (intensity) to start with, so get some good floating plants. Duckweed helps, but better choices would be Water Sprite (ideal for this), or Brazilian Pennywort; these are much better and more interesting as floating plants in larger aquaria. Second, reduce the duration significantly, down to 8 hours max. This can be whenever you want it, like when you are normally home. You will need a timer; the ones sold in hardware and other stores for table lamps will work. Believe me, this will only get worse if the light is not significantly reduced. It might have to go less than 8 hours, it depends upon the balance, which is my next point. There seems to have been an organics issue, but we need to explore that more. Are you using any plant fertilizers, and if yes, which and how often? What is the water change schedule, and how much of the tank? And what is the tank size?

Tank is 30 gallons, water change 20-40% once a week, use flourish comprehensive only during the water change.
My nitrites and nitrates are currently high, ammonia not so much, had a complete recycle when I had to get a 2nd new filter installed within a month everything has been upside down in the tank and lost a few fish due to it :(

First suggestion here is to up the water change volume. Nitrites should never be above zero with live plants, and nitrates should be low; no number is given for your "high" nitrate, but by low I mean under 10ppm. You numbers are related to the organics/algae issues. Change 50% of the tank every week; provided the tank water and tap water parameters are close (hardness and pH) this will improve things. Although I don't usually suggest it for planted tanks, do a light vacuum of the substrate during the water change.

Flourish Comp should be added the day following the water change, if you are using a water conditioner that detoxifies heavy metals. These will detoxify several mineral nutrients in Flourish so waiting a day is best.

Earlier comments on reducing light are critical and obviously still apply.;-)
