Reef Octopus HOB 2000

I set my salt water tank up 6 weeks ago (125 gall, fish and live rock) for the first few weeks my Reef Octopus HOB 2000 skimmer was doing fine, some micro bubbles but not to bad. I added a few fish a week ago and still was operating ok with just a few micro bubbles going into the water. But a couple days ago it started dumping so many bubbles that it now covers the top of my tank with a large amount of foam/bubbles. I have adjusted the height of the outlet up and down and re-positioned the foam pads on the outlet, I have also tried adjusting the air flow up and down and the only thing that stops the large amount of foam bubbles on the top of the water is shutting the air off completely. Not sure what to do or what is causing this. Any help would be greatly appreciated.

Is the skimmer overflowing rather quickly as well?

Carlos, When I have the air turned up to where the foam is flowing into the collection cup it does fill up the collection cup rather quickly with water, also I do have the collection cup adjusted high it is where the bottom of the cup is at the grooved line on the unit

There are several common reasons a protein skimmer will overflow but the most common is a chemical within the water itself.

Chemical Reaction - Some chemicals react with the air that the skimmer produces and causes the skimmer to over produce foamate. Chemicals known to cause skimmers to overflow are, red slime remover, medications, reef/frag putties (epoxy Putty) frag glues, water conditioners, dechlorinators, stress coat, NEW filter socks, newly mixed salt, bacteria (seeding) additives as well as other dosing medias. In order to remove these chemicals from the water column we suggest that you do several 20% water changes over the period of a month and add a good amount of fresh activated carbon to the system and change out every week till the skimmer has returned to normal operation.

Water level in sump - It is important that you place your skimmer in the proper water level. It is also important that the output of the skimmer is not submerged under water unless it is properly vented.

Inner water level - If your inner water level is set too high the slightest change in your water chemistry can cause your skimmer to over flow. We suggest that your inner water level to be set at no higher than the collar where the cup meets the body.

Blockage - The air intake otherwise known as the venturi, is like small vacuum pulling air from the surrounding environment. Often collecting dust and debris from the air which can block the proper amount of air to enter the pump increasing the water being pulled by the pump. It is also common for saltcreap to build up in the venturi and will need to be removed manually by scraping it away or dissolving in a solution of vinegar and water. Make sure you inspect the air venture, silencer and air hose for any debris or salt creep deposits. Also be sure the air hose is not bent or too long preventing proper air flow into the pump.
