SIGH, I must admit, after reading all yr stories that I just fell into their trap 2 days ago...
Me had a floating type hydrometer and thot i'd get an accurate swing type instead, but unfortunately Petmart was out of stock so I had no choice but to look in Rainbow- I've never bot much from this place cause the fish are RIDICULOUSLY priced (Blue Tang at $18 instead of $8 - i just bot from Pasir Ris Farmway)
The Deep Six they selling was at $25, and desperate me had to settle for it...now i feel so stooopig, SIGH
