OT, oxygenation, was Reverse Osmosis Question...
I don't understand the statement made by Sneaks:
".....also.....slower water flow allows more O2 to be introduced into the water on external filter systems" I'm not sure I understand gizmo either, so maybe I'm having a brain-dead day. From my understanding, oxygen gets into water from contact with air which has a higher O2 content than what's already in the water. The greater the surface area contact, the more opportunity for this process to occur. The better the circulation transporting lower oxygen water to replace higher oxygen water at the surface, the more efficiently all the water is re-oxygenated. The only time oxygen is added to water in a closed filtration system is AFAIK, when water is intentionally crashed into itself (like 2 tank drains meeting in a T connector). This causes air entrapment which increases the surface area exposed to higher oxygen levels. This process's efficiency (which is more typically used on commercial or industrial set-ups) improves as you increase the collision rate, increasing the entrapment %, but may cause unsightly bubbles sticking to surfaces in the aquarium. That's all I know. NetMax "gizmo" wrote in message ... Well there is a point here regarding the O2 specially when filters are replaced and O2 enters the system hence will effect the output... BUT..... shouldn't take too long and the O2 is out of the system..... In any case the effects are minor.... "NetMax" wrote in message . .. "Sneaks" wrote in message et... "Boris" wrote in message le.rogers.com... Water pressure sometimes dictates how efficient these systems will work. SNIP With that in mind.....certain filtration devices work better with slower, steady pressure....especially bio devices Could you explain or provide an example of the statement below? .....also.....slower water flow allows more O2 to be introduced into the water on external filter systems.....just my .02 thanks!
