Diatoms won't stop

[monfrey29]

I do regular weekly water changes 30%. I feed once a day, just a pinch. I just bought a new light fixture and new bulbs for my other fixture. I don't know my water perimeters right now, but brown algae keeps growing. What should I do... The tank has been running for about two months now. Will it pass?

It should stop given time, but I'd not predict how long. You can probably get it under control quicker with water change of 50% once a week, more light and more BN. In a 40g you might really need 3 to 5 BN to keep the glass clean, and they will help with the gravel and decorations. A good siphoning of the gravel may also be in order since silica promotes brown algae.

Might pick up 2 more BN this weekend, thanks. Its been awhile since I've been in this hobby (not a lot of funds) but I love it. So I am trying again. Thanks for your response.

Neerite snails can also help. We use a combination of neerites and plecos in our tanks.

do those snails multiply very fast? Don't wanna get few that will turn into a hundred.

Nerite don't reproduce in freshwater. They will lay eggs that don't hatch. Msjinkzd generally stocks them.

Will my peacocks eat those eggs? Or will I have to clean them out myself?

How long is your photo period? Too much light can come from either too high of a lighting density (i.e. watts per gallon) or too long a photoperiod. As the above tank has no live plants, I would recommend that you have the lights on a timer and have them come on only 2-3 hours a day when you are home to enjoy seeing the fishes. If the lights come on at 7:00 pm and go off at 10:00 pm it will be too short of a photoperiod for the vast majority of algaes to become established. Also, check that the tank is not getting additional light density and/or photoperiod from ambient light.

No, I've never seen fish eat them. You will see small dots on the glass. Easiest way to remove them is with a razor blade.
