NanoTank

Hi everyone

I have just converted my small freshwater tank to my first marine setup 2 days ago, and now am letting it cycle. It has black taitian moon sand, 3lbs of live rock (the tank has 2.5 - 3g of water). There is an (internal) side mounted filter which provides a strong current.

This morning I bought an air pump, line and stone and now have a tower of bubbles going up the centre behind the rock.

Are bubble towers like this suitable for nano marine tanks, it seems to move the water a lot, and will any creatures or coral I put in later be unhappy by this level of water movement? I put the airline in to increase the amount of oxygen in the water. The filter can pump air into the water, but the fine bubbles that come out stick to the bowled front of the aquarium and I don't like how it looks.

Below are a couple of pictures.

Any advice will be welcome. Thanks

well generally for marine tanks you need more circulation, and that a tank should have 1 or 2 powerheads depending on the size of the tank...but if your air pump is to strong you can get a gang valve and hook it up to that it lets you control the amount of air going thru...so you could have more or less bubbles

What an interesting looking tank. Kinda cool.

For saltwater, having turnover of 20x per hour is decent, with 10x ok in a smaller tank. The main drawback to bubble towers like that with saltwater tanks is the salt creep that you have to clean off the lights and tank edges. Can you hide a powerhead lower in back behind the rock work? Maybe aim it upward toward the surface to let the flow break up the water surface. Anyway you could rig up a small skimmer? It would help oxygenate and help keep the water cleaner.
