I got one to have a look at, maybe the quality has changed but the fittings aren't all that great in quality, the pipes arent straight and for the connection between the two to clip in place makes the overall spray bar bent again.
FYI no matter what dissolution technique is used, about 90% of the CO2 injected goes straight out the window. This is unavoidable. The larger the bubbles, the stronger their buoyancy and therefore the quicker the bubble rises to the top and escapes, so the idea is to try to dissolve as much gas into the water as possible and/or to reduce the bubble size as much as possible to reduce it's buoyancy so that the bubble stays in the water as long as possible and gives it a chance to dissolve. The "micro-bubble", if it makes contact with the leafy, also allows the gas to be transported across the leaf surface more efficiently, i.e. it simulates the leaf being in the air.Hi,
Does not using a spray bar expel co2 from the water? just tring to sort this out spray bar or NOT! perhaps pointing it at the glass and not the water would help co2 levels.
Hi, so if I understand correctly, to increase flow with two flow pumps, these should be placed at either end of my spray bar (which runs the length of the tank, on the back glass) and direct the flow in the same direction, forwards to the front glass. Will this only I crease flow at the two extremities, of will it create better flow all round. My tank is 120cm long.Hi,
3D backgrounds make things worse by disrupting the flow patterns in the tank. The best one can do with these, if removal is not an option, is to cut a slot so that the powerhead can be made to fit above or below to maintain the straight on angle. The next best thing is to mount it on the side and to point it as much as possible towards the front.

Yes, it is a known plant food, and that is great in a low tech tank, however, in a fuel injected tank the breakdown of organic waste is also trigger for algal blooms. Besides, we are already feeding the plants with nutrients, are we not?Clive, detritus/mulm seems to be a cosmos in regards to good are bad. It's known to be plant food but also organic to create bio film etc, excess ammonia etc.... What about gravel vacuuming do or don'? Is it important to have some for plant health?
I would start first by dividing the length in thirds (120/3) and place each of the two at 40cm from either end. If i only had a single powerhead them I would place it at the exact center (unless there were an obstacle there). In my view symmetry is all important...
Hi im thinking of keeping discus I have 45 litre tank an want to keep a pair is this doable ?
