I haven’t done a water change in 3 weeks and am finally gonna be able to do so tmr. Tank looks pretty bad right now tons on algae, looks like grass everywhere. Mainly in sand and a good bit on rocks. Sand will be easy to suck up and gonna try to scrub some off water. My question is what’s best way to prevent or limit this algae? I’m starting to get into more sps and acros so would to nice to limit it. Tank is 6 months old so still going thru ugly fazes I assume. Nitrates are 15. Phosphate.07. Any good ideas or just have to deal with it until tank matures more. Pics below.sorry for blue light. Thanks all
