junglejim Posted September 17, 2014 Report Share Posted September 17, 2014 Hi, have a new tank cycled and have a couple of fish and coral. There seems to be a reasonable amount of growth on the inside glass of what looks like brown algae. Is this normal? How often do you have to clean the inside glass? Thanks Quote Link to comment Share on other sites More sharing options...
Ira Posted September 17, 2014 Report Share Posted September 17, 2014 Hi, have a new tank cycled and have a couple of fish and coral. Cool. There seems to be a reasonable amount of growth on the inside glass of what looks like brown algae. Is this normal? Totally normal. How often do you have to clean the inside glass? Hugely variable, weekly, yearly. Clean it as often as you feel you need. Quote Link to comment Share on other sites More sharing options...
kinnadian Posted September 17, 2014 Report Share Posted September 17, 2014 Brown algae is always apparent after cycles, until you develop denitrifying bacteria (nitrate to nitrogen gas), and even then it depends on bioload. How big is your tank? What fish do you have? How much do you feed and how often? Do you have a skimmer or a GFO reactor? How long is your lighting cycle? What kind of lights do you have? Do you vacuum detritus (leftover food/fish poo/etc) out of the rockwork/sand? Quote Link to comment Share on other sites More sharing options...

How big is your tank? 200l What fish do you have? 2 clown fish How much do you feed quarter of a cube frozen brine each day and how often? Do you have a skimmer or a GFO reactor? Skimmer How long is your lighting cycle? 10 hours What kind of lights do you have? Led Do you vacuum detritus no (leftover food/fish poo/etc) out of the rockwork/sand? Are there any livestock which eat brown algae? Thanks Quote Link to comment Share on other sites More sharing options...

kinnadian Posted September 18, 2014 Report Share Posted September 18, 2014 That bioload in that size tank shouldn't be a problem. Is your skimmer removing good thick skimmate? Do you clean it fortnightly? You could try cutting back on your lighting, or using reduced lighting for a period of the day. Are your lights too bright? Is there a lot of leftover food? Are you vacuuming up excess detritus? (food and fish poo) Are you using RODI water? If so, have you tested the TDS of your RODI water? Where were the rocks from that you have in the tank? Did you cure them beforehand? Snails eat algae, but they are really there to remove small amounts here and there, if you are overrun with algae they won't make a dent. Plus, since the snails are adding their own waste to the water, you're not getting rid of the problem, just reducing it slightly. Quote Link to comment Share on other sites More sharing options...
