Effect of high Salinity

[Myka]

Hydrometers are handy, they are quick to use. I use one everyday, but I use my refractometer to check it every few months. Once the hydrometer has been calibrated with the refractometer it doesn't seem to wander off. I have one hydrometer that is dead on and one that is 0.007 off. That's huge.

Tony is right...don't change the salinity by too many points too quickly. I wouldn't go more than 0.002 per day, although going down in salinity isn't as harmful as going up in salinity.

All the coral seems to be doing good as well as the macro in the fuge.

The only new behaviour is from the goby who has decided that he doesn't like his live rock home and needs to dig a new basement - yet to be seen if he topples the live rock or not ?!?

I agree that I wouldn't trust the hydrometer, I'd prefer a refractometer but it'll need to wait until after the layoff

Does anyone know if there is any cuase & effect between brown/green algae growth and salinity? There is more green algae recently, but I chalked this up to a bit too much frozen food and a still newish tank.

I don't believe there to be a correlation between salinity and the type of algae growth. Though there will be some species that have certain ranges that they prefer. Personally, I'd rather have green algae than brown
