    Hi all

    Asking this because i recently got the new nozzle for my powercone 200i from good 'ol perky pets superstore(thanks david!), the air intake is now up from 1500L air/hour to 2200, the skimmer now takes in more air than water.

    Is there an ideal ratio or air water mixture, or do you just want as much air as possible?

    How did you measure the increased air intake?

    The powercone has a built in air meter which is analogue, cleaned it and everything so is reading right.

    there should be a balance. too much air = less water volume processed. too little air means less bubbles and therefore less surface area for DOC's to attach too. Most skimmers are designed with this in mind. If it is adjustable i would imagine you need to play wit it a bit until you find the sweet spot.

    Rah, thank you indeed dallas. This brings some interesting points to mind, remember the powercone has a grid wheel instead of a needle or star wheel so the bubbles are so fine they are almost invisible to the naked eye. With an air intake of 2000L/hr, according to Escobal, there should be around 16500L/hr of water intake which is not possible, so the skimmer pulls too much air? This is interesting because he mentions the bubbles will merge....

    So, in a good skimmer, the bubbles at the bottom of the skimmer should be the same size as the bubbles at the top of the neck of the skimmer? if the bubbles at the top are bigger, its an indication of the bubbles merging.....

    yes so you want to keep the mix as optimal as possible
