micro bubles?

so i have a 125 aga with overflows and i have a problem with micro bubbles in the dt i have two mag drive 7 pumps as the return i have way to many micro bubbles i don't know where they are coming from i have a filter pad just before the pumps and the pumps feed the tank with a flexable pvc tube, hose clamps to keep it tight not sure whats going on any help and the overflows are rated for 1200 gph i have two overflows does that mean 1200 total or 2400 total i wnat to increase my pump but i want to know what is the max gph i could run

 

Do you have a skimmer?
You can use two return pumps rated up to 1200gph after you calculate how much head you have. Luna

 

just got a aquaC 240 not hooked up and i run a seaclone right now

 

OMG....a Seaclone? Your going to see a hugh difference when you hook up the AquaC. Anyways, most, if not all micro-bubbles come from the skimmer. If your skimmer's outlet pours really close to one of your return pumps, that could be your problem. Luna

 

i got the seaclone as my first skimmer and had great results and just never stopped using it i do dose with vodka but the aquaC will be great what kind of pump would you recommend?

 

With an AquaC EV-240 you will need a Mag18 to run it. I would also get some PVC with a ball valve (3/4") to regulate, just in case it is a little much and you need some more control on the direct flow into the skimmer. You will like the 240. It will keep your tank very, very clean.

 

And you can get a small filter sock to put on the outlet of your skimmer. I do that and it eliminates the bubbles. However, you must be diligent about replacing the socks. I change mine out every other to every third day at the most. You just throw them in the wash (by themselves) with a little bleach on gentle, two rinse cycle. Let air dry (it dries fast). Then rinse again with RO water before replacing out.

 

One last post.......to answer the original questions. If you have overflows rated to a total of 2400GPH, then you could get two Mag 12s to do the job. At 4ft, each Mag 12 will give you 1125GPH (2250GPH total). Now this is a little close for my taste, so I would put ball valves on both to control flow to the return just in case. It is always a good idea to have a ball valve inline. If you can get away without using it, great, they tend to shorten the lifespan of a pump, but.......just in case........

 

You can use either a Mag 12 or 18 with that skimmer. How long have you been dosing vodka? Luna

 

about a month and a half at first i saw results with the skim mate being really black and then the skimmer didn't really get as much for awhile and then it went back to pulling a lot out i add 2ml a day to my 125 gallon and i use the cheapest vodka i can find
