Yes u can refill at welding shop as it uses same co2. Can also refill at fire extinguishers shops i think coz theres one here in kl refills for only rm12. Also about your inline diffuser which u use? and dont use it on inlet, ive read from many people that said it destroys the seals on canister filter after a long time

what kind of tong u using. If the valve is like the screw type i think anywhere also can refill. But if like me my tong is still with the fire extinguisher head so tricky maybe at outlet only can refill. Not sure welding shop will let me refill or not. If around Kl, search for syarikat city corp in sungai besi. they refill quite cheap.

Hey guys. Im making some custom dry macro ferts that i want to sell. If any are interested do let me know how much nutrient dosing u would like (ppm of each NPK in how many liters). Just have to mix powder with clean water then can start dosing into aquarium.

Imo honestly co2 is not really important, what u do need is ferts, regular tap water does not contain much or anything at all. Fish waste alone also wont provide your plants with all the needed nutrients. Also lets not forget about lighting, sometimes lighting is not strong enough.

depends on your budget. cheapest branded one i've used is fluval gro+. If tank not heavily planted can go for that. Seachem fluorish is more expensive and more ppl seem to trust it but imo offers less when comparing the guaranteed analysis of the nutrients.

but if u got money to spend, APT complete All-In-One Fertilizer by 2hrAquarist Dennis Wong. I havent used this before but looking at the nutrient levels for each dosing its better than the rest.
"Each 5ml per 100L dose adds 3.8ppm Potassium (K), 1.8ppm Nitrogen (NO3), 0.7ppm Phosphorus (PO4), 0.05ppm Iron (Fe), 0.4ppm Magnesium (Mg) and additional amounts of Boron (B), Copper (Cu), Manganese (Mn), Molybdenum (Mo) and Zinc (Zn).

The above dosage is designed to be dosed 4 times a week. So the total per week adds up to: 15.2ppm Potassium (K), 7.2ppm Nitrogen (NO3), 2.8ppm Phosphorus (PO4), 0.2ppm Iron (Fe), 1.6ppm Magnesium (Mg) and additional amounts of Boron (B), Copper (Cu), Manganese (Mn), Molybdenum (Mo) and Zinc (Zn)." picked from his website

can u show us a picture?

Guys i have a bunch of rotala greens, regular rotundifolia and some hra (not red coz high nitrate) that i wanna give away or sell at small price. easily more than 50 stems here. anyone wants?
