What's going on???

I assume you cured your rock in your display tank. If this is the case, you have all kinds of nutrients in the water from the curing process which are, and will in the future be, causing you all kinds of nuisance algae. If you have used treated tapwater in the system, nutrients in the tapwater are likely compounding the algae problems.

First, clean the glass. Get in the habit of cleaning the glass at least once a week, preferably before weekly water changes of at least 15% of your total water volume.

Second, right away, do two 50% water changes to reduce nutrient levels. Use RO water for these large water changes as well as for weekly water changes and for top up purposes.

Third, if you have any mechanical filtration in your system, clean the filter media throroughly in outgoing changewater. Clean filter media weekly, as well.

Fourth, add snails to your tank. Some say to go with one snail per gal, but I generally think that's too many snails. I use about one snail per 3-4 gal quite well. Sorry, I can't advise you which snails are best for the algae problems you're having. Hopefully others with experience in this area will help you out.

Providing more information about your tank - such as how long it's been set up, size of tank, if sump/skimmer are used, if tap or RO is used, if you cured your rock in your display tank - would be helpful so we can help figure out the cause of the algae problems so you can reduce them.
