Diatom Issues
My 55 gallon tank has been setup for around 6 months now, and I continue to have diatom issues. It is covering my crypt leaves and hornwort the most, as well as alot of my substrate and glass. I remove it manually about every other water change. I have kept up weekly to bi-weekly water changes, depending on how unsightly the diatoms get. It has recently gotten worse after I upgraded my lighting to two 48" t8 tubes.

I am dosing weekly with Flourish comprehensive, and my lights are on 8 hours daily. I would say my tank is moderately planted.

I realize in the grand scheme my tank hasn't been up for that long, but I feel like I should have made some headway with my diatom issues. I figure upgrading my lights has likely caused some more balancing issues that my tank needs to figure out as well. Should I just stay patient, continue to remove manually with water changes, and keep the faith? Any advice?

Try reducing the amount of time the lights are on..

Diatoms although unsightly will go after a period of time..took 8 months for my 75g tank to get over them when I originally set it up.

Thanks Tazman, any ideas how short I can go with the lighting and still be ok with my plants?

If only my BN Pleco liked my diatoms :|

Just be patient and keep doing what you're doing. Eventually they'll go away. Some of my tanks took up to a year for diatoms to go away and some tanks never had much a problem.

You're BN doesn't eat the diatoms? Mine ate that stuff up!

I never see her doing much, or see any obvious lines in the diatom growth. Maybe my 55 is just too big a job for one little BN...

I would really like to keep a school of oto cats but I can never find them locally. I like them as a fish, and BONUS they love diatoms. I'll continue to keep an eye out for them.
