No problem. Sorry to those qho asked me where to buy, I cant seem to send pm.... so I will just post here, I saw it being sold at Nature Aquarium, at Balestier Shopping Center. It's a planted tank LFS. There's a cheaper brand, Hanna which looks exactly the same, even the box. Abt $40. Im using one. Can find in many freshwater LFS.
Take note that these pH meter are not waterproof, not like the Eco brand but it cost $75.....
