Corinna if you want you can just turn off the flow, and pour RODI over the screen to kill the pods. But if the algae is thick I would clean it (and leave any turf on it.)

jfdelacruz on the RP site: "Overfeeding does wonders! i dont know how and why but, the ATS seems to be an extra 20 gallons for my tank because even if I overfeed, nothing in my tank seems to be going bad! water is always crystal clear too! (I do have seagel in there running for about 2 months already) this ATS is a blessing."

Ciao SantaMonica, would it be okay if I translate some of your advice for my friends on a forum here in Italy? Ive tried redirecting them to your thread, but the language barrier is proving too difficult. Corinna xx

Reminder Of The Day:
If you are home when a power outage occurs, then just like you would manually try to oxygenate your tank, you would also take the screen out and set it in some water (even tap water in the sink.) Problem solved, no damage. It can sit there for two days with no ill effects. You could even put it in a shallow pan of water outside in the sun, where it will probaby grow
If you are not home, however, it becomes a question of which you lose first, your screen or your whole display. Long term (days) you are going to lose both, so we'll look at short term (hours). Somewhere in-between is the question: If you are not home when the power goes out for 2, 3, 4, 5 hours, etc., then how much of your screen will you lose, and how much of the nutrients will be "released" back into the water?
Well, most screens are designed to be up and out-of-contact with the water, so there will be zero "release" of nutrients during the power-outage. And floating screens that stay in contact with the water will not die or release nutrients at all in a short-term outage, because they stay wet. So immediate release of nutirents is not a factor in any situation.
The real question is long term loss of filtering, i.e., how much of the screen will die off during the outage. When you get back home, the screen has been drying for a few hours, but is still moist. What you do is put it in your sink with water and give the dead parts a chance to fall off. Not sure of how much time is needed, but just do a regular cleaning of the screen every few hours until it seems that most of the dead stuff is removed. Doing this in the sink will prevent any nutrients from getting back into the tank. You then put the screen back into operation, and it's no different than if you just did a regular cleaning. And this is the worst case.
I myself unplugged the wrong plug once and left the screen 6 hours with no flow. The fan was still on, but the lights were off at the time. It was all still moist, yet a bit hardened. I did not think at the time to remove the outer layers of dead stuff, so I just put it back into operation right way. What happened was the next day or two there was a very slight increase in N from zero (clear Salifert) to a very slight pink; probably got up to about .5 or 1. P did not ever increase, however. And this was without properly removing the dead stuff. So overall, I don't think power outages are really that eventfull for scrubbers.

Thanks SantaMonica, I will get to work on translating when I have finished weaning the new parrot babies. Today I had a bit of a disaster. In my seahorse tank I keep turbos and astrea rugosa snails as part of my cuc. The turbos have been happily doing their thing, it didnt occur to me that the food source for the astrea(algae) has been steadily diminishing since the scrubber really got going.Astrea are big snails, with an insatiable appetite for diatoms,hair algae etc; today when I checked the screen(compulsive behaviour on my part!), I found it neatly scoured brilliantly clean over 1/3 of the surface. The astrea had found it last night and grazed contentedly for ages.Im surprised they hadnt had the lot, hope they get indigestion. That little screen was my pride and joy!! They have now been banned to the big tank where theyre sleeping off the night's binge.Anyone keeping these critters BEWARE
