Position the spraybar below water but pointing towards surface. That creates plenty of agitation without any noise. As long a the surface is disturbed you'll get better gas exchange.
Jim you need a rated flow from your pumps/filters of 4500lph. The pumps/filters will not perform at their rated flow due to the pipes, gravity (head), narrowing at inline equipment points. Perhaps a system with a rating of 4500lph will perform at 2500 or 3000lph, it varies depending on setup...
Joe. I have the same dilemma. I'm about to move my tank and and it would be more simple to combine my 2 loops into one. As you know I have a filter rated at 1700lph driving a spraybar with no inline attachments and a 3000lph external pump driving the main spray bar with a inline diffuser and...
Thanks Clive. I thought it odd because I believed the increased surface agitation would drive off more gas so I'd lose CO2 faster. I suppose that could still happen but I'm dissolving more CO2 which makes up for any increased loss.
I've posted a video of the effect of the flow on the tank...
In my original post I said I added a 2nd filter that had a rated flow of 650lph. Probably best I'd left that out as its confusing. I'm talking about 432lph from the Eheim Pro3e which has a rated flow of 1700lph.
Well I've ditched the 650lph filter. I've removed all obstructions (co2/heater)...
The filters clean, the pipes are clean, the media trays are 66% full. I'm about to switch things around so I'll let you know what happens when I replace the outflow with a single pipe.
I'm suprised its taken me so long to measure the flow from my filter. I've read over and over that I need good flow and I understand why. I assumed that having a rate 1700lph filter would be enough even though I expected the actual flow to be a lot less. Recently I added a small external...
Hi
My first post :wave: . I'm a week away from collecting my new tank and related gear most of which is bought and paid for. Having a few weeks to wait allowed me to trawl through the forum and I'm impressed with the information available here.
I have purchased an Eheim 2076. I chose it...
