Thanks, appreciate it. I can assure you there is no noise from my ATS and I wasnt going to turn my return pump off and let the tank drain down to stop the draining noise. However with my cabinet doors closed you can't hear any noise emanating from inside the cabinet.
Does your skimmer production significantly increase for a time after screen cleaning Atoll ?
Can't say it does to be honest. I will try and pay particular attention to it when I do my next harvest Tuesday or Wednesday and let you know, if I remember that is.
The reason I ask is; Dana Riddle told me about when he ran his coral farms. He used skimmers & the old school horizontal style Adey algae scrubbers. When servicing the scrubbers he would scrape off the excess algae on the screens, rinse them under fresh water, put them straight back into the system, and then his skimmers would go nuts for an hour or more.
Harrr right. Well.my skimmer certainly doesn't kick off like that if at all. My Ulva is only under the cold water tap a short time and after harvest there is only a short length left on the screen around 1/2". Perhaps if there where more Ulva on the screen the Ulva would release DOC or whatever would cause my skimmer to go nuts.
Dana grew several varieties of genuine 'turf' algae on his screens, as opposed to Ulva. The effect may have been more pronounced because of this ?
Well, I used to grow GHA or turf and I do get some on the screen with the Ulva but the Ulva is much the dominant algae. I found the Ulva grew much faster than GHA under the same conditions.
Yes, Ulva is the Alpha algae for filtration
It is also arguably of course the most easily of algae to grow although those with GHA in their DT may argue against it.
My tank is in the middle of my home, adjacent to the kitchen, in a main living area. My pH is always 8.2 to 8.3.
Good evening, I would like to say that was a very educational video! I always thought that you were supposed to scrape the scrubber screen down to the plastic. You have just shown me once again that there are many ways to get to the same results! Do you find that leaving some of the algea on the screen instead of scraping it clean helps to have it grow quicker and better? Where did you come up with the technique of just trimming it with a pair of scissors? Thanks
My tank is in the front living room we go into in the evening mainly.
Thank you. Yes trimming it back to within 1/2" of the screen seems to give it a better start, well not start exactly as it still very much growing. Just by seeing the amount I harvest every 4 or 5 days shows how well the Ulva recovers.
3 mins 55 seconds. I could have done it quicker mind lol.
I run the water feed 24/7 as you must. The LED lights are currently on for 20 hours. I have them on through the night with an overlap either side of my DT lights. So for 4 hours in the middle of my DT light cycle my scrubber LEDs are off.
When the light is on photosynthesis is occurring and PO4 & NO3 are assimilated into the algae, i.e. removed from the water. If you want PO4 & NO3 levels to be higher have the light on less than 24/7.
