Red Sea Prizm Skimmer

[Anthony]

anyone use this prizm skimmer b4?. any comment on this product?

what is the cost in the market now?

[KingFish]

Was looking at this for a while, believe Tango, Valleyman and ZeroCool are using them.

As far as I know, they're fine for small tank, but may not be able to cope with the larger ones. Its a hangon, so it wouldn't take up too much spade. You would fare better with real testimonials.

There has been some discussions on the PRIZM, do and search.

[TanGo]

My prizm is worth its price..

[Fishfreak]

Mine works well on my 80litre reef. Will work better if I can get some kind of surface skimming going as well. Don't believe the 90G sales talk, though.

[RMX]

haha.. it think its worht a rat's ######

skims salt water most of the time

flowrate alrady set to very low, nearly closed, still overflow

[Anthony]

how much u guys bought ur prizmskimmer?

izzit really skimmless type?

can i drink coffee or greentea?

tot of getting 1 for my 60G tank.

Hi Joe,

I won't recommend this for a 60G because i feel its juz ok on my 30G

I'm still trying to get drier skimmage.

Cause the brownish water I got doesn't smell bad.

RMX,

I think you did nto set it correctly, thus overflow. When you put the tube into the the corner outlet, you must turn the control valve untill all bubbles are suck through. There should be no sound at this stage. Then, change the air tube to the secnd hole and the sound change and the prizm will start skimming.

I'm using one on my 90G and it works well. I get very dark brown skim about 1/4 cup every 2 days.

i made sure the are no bubbles in the water inlet tube before changing to the air intake plug.

i have to set to pretty low flow in order not to let it overflow. furthermore, the skimmate is still kind of watery. just light brown color.

[Chris]

RMX,

I experience the same thing as you the first 4-5 days I started using the Prizm but It went to normal after about a week. I discovered the water in my tank is clearer than before when I was using the sander system.

[Anthony]

can any 1 take a pic of ur prizm skimmer cup.

i want see how Thick gunky skimmate

just drop by marinelife. @@ the display tank using prizm. seem quite ok leh.

*see the pic below. can reach that stage? wahahaha

[Chris]

Mine is as thick as that. Also, in the funnel's side, it can be thick as semi solid.

chris, wats your flow like. how wide u open the tap? i been using the prism for at least a mth already. i do get solid gunk on the funnel walls. but the skimmate still watery and brownish at best.

[Chris]

My flow is always at the maximum.

[TanGo]

Here's mine.. as promise..

[onghm]

Hi Tango,

Mine is about the same as yours.

Have u tried smelling the brownish liquid ?

Hi Chris,

That's interesting.

If I turned it to max flow, it will be very watery.

Anyone knows what's the logic ?

I will be one happy dude if I can get darker skimmate man

Thanks,

[TanGo]

Just turn down your bubbles.. Dunn let the water level get too high.. maybe around 2cm from the rim...

[Anthony]

tango ... hmm look like quite dilute.

chris u say urs flow is always at the maximum. and u can get Thick gunky. how many days u wash ur cup?. once a week?

[TanGo]

Every two days..

If I turn down the flow, the skimmate will be darker and drier..

[wedgee]

Hmmm how do u guys get dry skimmate in the CUP itself leh? I turn up the water till the bubbles can pop at the top of the mouth, and end up with the color and watery skimmate like yrs, Tango...If i turn it down, the bubbles stay in the mouth and NO skimmate is collected in the cup...how to get dry skimmate in the cup?????

Experience the same thing as Wedgee.

Chris, any other tweaking u did to get that sort of gunk ?

[TanGo]

Ok.. Here is the tricky part...

First, you have to make sure that your prizm is sealed air tight.. Meaning after washing, the whole cover is placed back properly. the air tube fixed properly...

Then you have to play around with the valve.. I tried a few different flow rate and it gets different color skimmate..

Right now, I am experimenting with around 2cm below from the rim.. So more bubbles have to be formed to push the skimmate into the collection cup.. Resulting in darker skimmate..

If you have plenty of dark color skimmate, means that you are over feeding your fishes.. Hehe.. I have been controling my feeding patterns and seems like my NO3 has been reduced and also skimmate is not as dark as before..

Those are my own observations.. See if it works for you..

[Chris]

I don't do much...just wash the cup once a week when it's about half cup. (dark brown gunk) I don't even wash the set. And my flow is always max. No idea how to overcome the watery or no gunk problem though I've experienced that before. First week of use, all watery, then slowly became dark and until now ok.

[UFO]

Chris,

How many fish u have? I have only 6 small fishes in a 3ft tank & all of them are on strict diet.

I have the similar problems as u guys. My valve is only at half flow. If i turn on just a bit bit more (maybe 1mm) i get overflow.

I have another problem. How u guys avoid getting micro bubbles flowing back into the tank??? Please please please help

Oh, something that i notcie may help. If yr inlet is somewhere near good/strong water flow, u get more bubbles even if yr valve is only half or 3/4 open. Try pointing yr powerhead outlet direction towards the skimmer inlet.....not next to it of course

[ZeRoC00l]

Just to share my experience.

I follow strictly to the instructions: tune valve till water level just below the black O-ring.

>>>>>>>> For this setting i get almost coffee skimates. But i must clean the cup often as alot of gunk gets build up on the inside of the reducing part of the outlet

Just tune the water level to below the O-ring and wait till the shimmer is broken in then adjust again. For darker or lighter skimmates.
