You can get varying issues. Not enough salt, your corals will suffer. I had too much, hence too much Ca, and my sand solidified. Rock solid slab 2x4 ft. Also not good for fish or corals to have too much. For the cost of a refractometer, I'd go get one today before the stores close.

Rock solid slab. Haha :P You could have made a table top with that and label it as "live sand table top" :D

I broke it into 6 or 7 pieces to remove it. No table :)

Jokes apart. That must have really sucked :(

Ya, I tore the tank down I was so ****ed off! Could have avoided it with a real refractometer :razz:

my frag tank took a face plant this month due to a huge salinity increase caused by a hydrometer , bought a refractometer and figured out sg was .31 when hydrometer said .24 real pain to bring it back down .

Looks like hydrometer is more notoriously famous for showing lower reading than higher reading.

If you can't afford 50 bucks for a refractometer your definately in the wrong hobby.

I can definitely afford a $50 refractometer but like I said before, I can't get it before the end of August since I will be leaving town shortly and wont get it through shipping :) And there's no $50 refractometer available in the shops (all around $90-$100 and that I can't afford; atleast not a $100 refractometer since there are $40-$50 ones available).

If you like depending on where ya live I can stop by and check for you with my refractometer.
