co2

I just got a dissolved oxygen tester. As I suspected, my tanks are highly aerated (25mg/l and 20mg/l). These tanks are aerated with just regular air which suggests the ratio of oxygen to carbon dioxide is approximately 21:0.04 in the tank just like the atmosphere. (20mg/l oxygen : 0.04mg/l...

Hello Everyone! I'm new to the forum, and would like say thanks to everyone who will post on this thread. I currently have a 60l planted tank, medium stocked. I kind of cheaped out on the diffuser and am just get large bubbles of co2. I'm looking at two options to switch, namely a cork...

Hello - I am new to this forum. I've had a small aquarium for awhile, but am upgrading it to a larger one for more fish/plants. I will be having a CO2 line and have a few questions on valves. Are most people using solenoid valves on timers?

OK so new to the whole planted tank thing but right now that's besides the point. I have a low tech tank so low that I made a diy air/water displacement filter. The output tube mainly puts out air with spurts of water (about 1 gallon per hour). I also want to get make one of those crappy...

I have been in the planted aquarium hobby for over a decade and have had a 330 gallon tank for two years now. But I have had to return to the basics with regard to CO2 injection because the system I set up - 4 inline difusers, 2 large reactors - reduced the flow to the tank so much that there...

Hey everyone, I grew up with FW aquariums and have a good understanding of how FW tanks work, but limited physical experience. (One 50 gal/several nano fish only tanks, as well as a crazy awesome 30gal palludarium). I've been keeping impressive SW tanks for years. My uncle has a retail lounge...

Hi guys, I've just redone my tank to add plants and junk, but my questions is, Im assuming I need to take the oxygen bubbler out because the plants need CO2 not oxygen, and they will provide oxygen for the fish themselves. But I'm thinking I need to provide CO2 for the plants? how does that...
