Algea and green water prob. In 55 planted

Hello all.

I've have had my 55 planted tank up for about 3 months now and since a week ago my water has turned really green even after I did a 10 gap WC. I've also had a lot o
green hair looking algea. I got 6 Otto catfish to clear up that problem but they can only eat a certain amount.

Tank specs are: 2x 32 watt 6500k T8 the lights are on for 8 hours a day. I haven't use any frets for almost 3 weeks.
1x tetra 40 gallon whisper filter.

I just turned up the flow on the filter thinking that that might be the problem. Now the whole tank has at least a little bit of flow. I have been feeding extremely minimally too. I have 3 neons 2 rasboras 5 glowlights 2 small balas 2 small angels 2 rosy tetras and 6 ottos. Doesn't really seem like my tank is overstocked either.

The tank is moderate to heavy planted

I would advise you start fertilising again. This might seem counter-intuitive but the fertiliser will allow the plants to make more use of the available light and nutrients, thus hopefully starving out the algae.

Green water is caused by unicellular algae, and this occurs almost solely due to excess light. Light and nutrients must be in balance for the plants to use, and no more, or some form of algae will take advantage. Stopping the source of nutrients (fertilizer) will actually make it worse, as the plants without food cannot make use of the light, as sik80 said.

Reduce the light period by 1-2 hours and use the fertilizer regularly. However, it has to be suitable fertilizer, with the essential nutrients. What type do you have?

I have flourish comprehensive fert. Could I keep my photo period the same and take one of the bulbs out? I also seem to have a lot of dead plant matter at the bottom of my tank. Should I siphon this out?

This is a 55g, am I correct in thinking it is 4 feet in length? Removing one tube would half the light which I think would be too little for the plants. Try just dosing the Flourish weekly.

The dead plant matter is not normal, any idea what caused this? This adds to the organics.
