How Do You Prevent Algae Spread?

My tank's been getting overrun with algae lately, and I'm not sure what's causing it. I've got a 20-gallon with Java Fern, Anubias, and some floating plants. Lights are on for 8 hours, and I do weekly water changes. Any tips?

Algae can be a real pain. First, check your nitrate levels. High nitrates often fuel algae growth. Also, consider reducing your light duration to 6 hours. Floating plants like Duckweed can help by shading the tank. What's your current nitrate reading?

Lighting is usually the culprit. I'd cut it back to 6 hours and see if that helps. Also, make sure you're not overfeeding. Excess food decays and adds to the problem.

I agree with this. Nitrates are key. I'd also add that adding more fast-growing plants like Hornwort can outcompete algae for nutrients.

Thanks for the advice, everyone. I'll test my nitrates today and try reducing the light. I've got some Duckweed coming in the mail, so hopefully that helps too.

Another thing to consider is your water flow. Poor circulation can create dead spots where algae thrives. What kind of filter are you using?

I had the same issue until I started using a timer for my lights. Now they're on a strict schedule, and the algae's chilled out. Also, nerite snails are great for cleaning up the mess.

I've found that keeping the tank clean and doing small, frequent water changes helps a lot. Algae loves dirty water, so staying on top of maintenance is key.

Yep, cut the light and up the water changes. That's the way to go. Also, maybe throw in some shrimp if your tankmates allow it. They're algae-eating machines.

Exactly. Consistency is everything. I do 10% changes twice a week, and it keeps things in check.
