Dymax IQ3 or IQ5?

Btw,those using iq5, what do u all use to cover the holes that flow over to the IOS?

The entire back area of the IQ5 is an IOS. First chamber is for filtration media. Next is sponge chamber. Last is where the powerhead is installed. Are you referring to the intake slots or the round hole between first & second chamber?

The round hole is there as a water bypass to the next chamber, in case media get clogged from neglected maintenance. Without this round hole, the chamber will flood and spill over.

If you have water flowing freely between first two chambers, it simply means you've topped up too much water.

Personally, I lay a thin layer of filter wood, covering the entire first chamber plus the round hole, because I over-fill slightly for water loss from evaporation. Wool is easy to remove and extend intervals between maintenance.

I thk concern is just the holes in the first chamber,any pics to show bro?my water doesn't flow over to the 2nd chamber and I keep needing to top up water to the powerhead fillter..btw u just cover the whole chamber with wool?what abt the media?

It is easier if YOU show pics of what you're doing.

The flow of water should be through those slots, down the chamber, go to next sponge chamber, then to powerhead.

You should not see a flooded first chamber but when you see tiny air bubbles coming from the out-tube, you know it's time to top up water.

Water loss from evaporation is normal but more frequent top-ups if you're using additional fan to cool the water... and that is part and parcel of the hobby, bro.

I use a soft net to cover the Inlet as of now.hope still enough to stop some shrimps going thru.mine doesn't flow over to the 2nd chamber,is it correct?but the water level is almost nearing to the brim
