RED... GREEN And Brown ALge
 

:frown: ITs normal for a tank thats been up for 4-5weeks to have Redslime alge, green alge and brown alge on sand and rock right. Just like happened over night seems like. I do water changes plus i use a bastert to remove alge. So what im askin is how long does this last tank looks like pooh.

Are you using tap water for water changes? If so, the water changes may be the problem. Lots of algae loving nutrients in tap water.

Naw i have a 5stage RO setup tanks really new. Plus i had to do a transfer right away so its 4-5weeks old and has 2 fish 1 shrimp 4 corals
its a 75gal tank with 75gal sump 20 gal fuge with Macro no skimmer.
