I have a new 44g tank I set up last weekend w/ a aerator and a Fluval 305 w/ the output on the opposite side of the tank from the aerator. I added some API Tap Water Conditioner day 1 and some SeaChem Flourish day 2 for some plants that I put in there. The bubbles from the aerator, instead of popping when they reach the surface, just get blown around once they circulate over to the filter output, clouding the water much like in the OP's pic from the first post. If I turn off the aerator, it clears up after a bit, but I really don't want to do that. I don't mind turning the aerator down, but I just feel that the bubbles should pop when they reach the surface.
If you have plants in the tank, you should have as little water flow from the filter as you can, just what the fish require. Some fish need current, so that is fine if your fish do; but many "forest fish" do not and the flow will keep them unsettled as well as be detrimental to the plants. Have a read of the sticky at the top of the Aquarium Plant section entitled "A Basic Approach to the Natural Planted Aquarium" Part Four deals with filtration and explains why this is detrimental. Here's a direct link: http://www.tropicalfishkeeping.com/a...um-part-34858/ This will also dealwith the bubbles problem.

I'd be happy to answer any questions from that. Byron.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

Again, thanks, Byron. I keep reading and re-reading the stickies around here, and sooner or later some of it will sink in.

I understand the reasoning re: the aerator and minimizing filter flow. I turned down the filter as much as recommended by the manufacturer (~50% of max), and I don't think there's that much of a current. I also have the aerator turned down, but it's part of a volcano ornament that I really like, so I really want to keep it on for effect (actually, I've been thinking of putting it on a timer to 'erupt' for 15min/hr, but am wondering if the constant on/off would stress the fish). As much as I want to have live plants, they're kind of tertiary in my tank, after the fish and the 'look' (if I have to, I'll go to plastic or silk plants). My real concern was whether there was something in the chemistry of the water that was keeping the bubbles from popping at the surface, and, if so, whether it was something that I could or should address.
