Week 2 and I have an Algae Bloom

The first few days it was a mild white cloud. Did a water change and nearly had it perfectly clear. I then added 3 amazon swords, 2 bunches of hornwort, and a piece of treated driftwood. I will add that it's a dirt tank.

So as the week has gone by I have been leaving the lights on for 10 hours or more. My lighting is a basic single fluorescent bulb. Nothing intense. Hence hardy plants.

So with everything mentioned whats the best way to rid myself of the green cloud?

From the sounds of it... you have green water...

Lights should only be on for no more than 8 hours a day. Get a timer and run your lights on a timer so you don't forget to turn them on/off.

To help with green water (thats what it sounds like to me at least), people say to use a UV sterilizer. Also, doing 10% water changes daily won't hurt either

Pics would also be helpful

Increasing biological filtration and allowing floating plants to shade the tank have worked for me. My very first monster case of GW cleared up when I dosed potassium nitrate but your dirted tank should have plenty of nitrogen. Your tank is brand new without an established biofilter, maybe as that matures the GW will clear up.

Not sure water changes are always a good idea for low tech tanks, you might want to search that topic more. Allowing the hornwort to grow to the surface and completely shade the tank might be a way to go.

I'm gonna give the "Surface" idea a go. I've read about it elsewhere and since hornwort is so cheap it seems a good solution. The reason I was doing so much light is because I read somewhere that Amazon Swords needed that much light in a day. Thanks for the advice. I've already done a water change-nothing major. I'd say about 10 gallons removed. I'm just trying my best to play some patience because I want that crystal clear tank. But tanks are time. This I know.

I can post some pictures soon. I've been doing most of these discussion boards while on some free time at work but I can get to that hopefully soon.

In low light tanks reducing water changes for a time may help resolve the problem or overdosing excel to keep the c02 stable.

150g glass tank
40g refugium
30g sump
two overflows, a closed loop, several Seios for circulation
ASM G2 skimmer
Korallin 1502 calcium reactor
Reef Octopus bio pellet reactor
Via Aqua Poly Reactor for GFO
Lots and lots of corals!
Blennies, gobies, one tang, leopard wrasse, mandarin goby, clams, shrimp, etc.
