I'm thinking of buying a calcium supplement (API Eco Calcium) for supplementing calcium for my 55 gal tank. it is cheaper than sera's calcium plus, and i believe that aside from supplementing calcium, it does have other benefits (as per API), and so on... well, two part solution is way way cheaper than this, but i do not have the idea on how to do the mixing/dosing, etc... and with my experience, i could not store sodium bicarbonate solution because it rots. gusto ko makatipid, goal ko kasi sa sarili ko na nag e-enjoy ako, pero mas mura, kaysa manood ako ng sine linggo linggo... :p
api said that their supplement provides calcium needed by invertebrates, etc., without affecting the pH, nor the alkalinity. but if there is still a way to save money, i'll go for it. calcium supplement is ±500php, sodium bicarbonate and calcium chloride is ±200php lang. and i like the thing where you get busy with your tank especially for a lonely home boy like me :p
any inputs will greatly be appreciated...
