    Hi Guys

    still a newbie, my setup is running fairly well, All fish seem happy.

    I have a 130D RedSea, its placed in a room with 24000BTU aircon, so temp in the tank usually sits between 25 and 27.

    My sand seems to get brown in a matter of a day after cleaning it. It will litterally be white and then it turns brown again.

    My PH levels and Nitrate levels are all perfect. Tank was running for 5 months with previous owner, and i have had it running for about a month and a half at my place.

    i use Red Sea Coral Pro Salt mixed with RO Water. water changes done weekly. I dose with Sea Chem Fuel twice a week, Seachem Nitrate remove every second day and Red Sea Phospate remove every other day.

    Can someone assist? what can be causing this? i also have a some red algae forming on some of the rock, i brush this of every 3 days.

    Hi Belinda, thanks for the reply.

    the thing is, this happens a day/two after each weekly water change.

    Havent added anything new to the tank, its got the original setup as had buy the previous owner. Any suggestions?

    does anyone know who stocks a battery operated sand/gravel cleaner that has a filter back which cleans the sand, and pushes water back into the tank (trapping all the muck in the bag). I see a few overseas, but none in SA. Tank doesnt look so grand with the sand like that, and the fact that it takes just a day or two to get like this after a water change is troubling.

    New tank, just let it be. It is part of all the stages that a new system goes through. Continue with your regular water changes though. Tanks looks awesome! Remember a 5 month old tank is stil considered as a new system.:thumbup:

    thanks everyone :)

    will let it sit and see how it goes after 4 more water changes.

    Also, my temp usually sits around 27 to 27.8 , do u think i need a chiller? im in durban, and we are having pretty hot weather at the moment. On dull days my temps sit at around 25 to 26 degrees.

    just wondering, i have the aircon on almost all day for the tank, wondering if running a chiller would be cheaper on electricity

    Diatoms are a result of you having moved the system an things going a little out of ballance, stay with the water changes (10%) or so and just let the system be. Things need to ballance with bacterial populations and excess nutrients being released and then consumed.

    What I think might be your primary problem is it sounds like you are vacuming your sand bed often and might be pulling up detritus and or removing lots of good from the sand bed (micro worms, bacteria, bristle worms etc etc etc). I would suggest leaving the sand to go brown with diatoms and not vacume at all, let things settle without dosing, or vacuming or fiddling. the tank just needs some time to adjust to the changes its gone through.
