Thanks for this video.I need to blackout my tank for 24 hours to get a medicine working and was worried that I would lose algae.Its a blackwater tank and it looks very clean so the little algae I got is essential for my shrimps and the ottos in there.Seems that 24 hours won't affect algae which is great ❤❤
Hi there, I added the cling film for 3 reasons. One, to make sure that if I made noise in the studio, the fish won't want to jump whilst they are in complete darkness. Two, the fish would have no food during this time and I didn't want my fish, especially the shrimp to jump out. Three.....I didn't want evaporation of water evaporsting on the black bag and condensing and dripping on the outside of the tank. The reason I aerated the tank was to ensure fish had enough oxygen and were not too stressed as they would not have food for 5/6 days. Hope that helps
I have an annoying cyanobacteria problem in my tank and looking to try the blackout method. I have heater in my tank, wouldn't wrapping it up like that mean it would get too hot in there? Also how would gas exchange take place when it is sealed? I'm worried if I do this it will kill my fish.
In my opinion, the blackout method should be your last resort in getting rid of green hair algae. Green hair algae is caused by over-fertilised water, meaning not enough plant mass to uptake the fertiliser dosed in the water column, too high light intensity as well as too little CO2 injection. In other words imbalance between fertiliser, light and CO2. It's hard to get the right balance in the early stage, but once you hit that sweet spot, no algae will ever dare to grow. I've also noticed the fish food you feed the fish goes everywhere in the tank. Note that uneaten fish food deteriorates and turns to ammonia which could also trigger green hair algae to grow. I might suggest you turn off the filter while feeding the fish and remove uneaten fish food as much as possible before turning on the filter again. Keep up the good work buddy!
Hi, I dose three of my tanks equally. I think your right as the algae came up after a mass trim. The trick I will try when trimming next is not dosing as much after trimming.
I think your right about the food, the scape has so many nooks and crannies as the black larva rock is layered up, this tank ideally needs 2x water changes a week I think.
I find frequent water change in lower volume say 2-3 times a week at 20-30% is better than a big water change once a week. It helps neutralise the water parameter, removes algae spores, removes excess ammonia, thus, lowers the risk of triggering any kinds of algae for that matter. 😉
@@spardamustdie47 yep, I think your right, just finding the time to do that with all tanks whist working full time is hard for me haha. But agree, I would like to do 20% water change 3x a week rather than one full 60-70%. I think less volume but more frequent is better for fish too.
Logically thinking, that means you have to dim yours lights so that this algae won't come up again.. no? Because if the parameters remains the same as before (strong light, Co2 etc etc..) you will see it again after a few days i guess.. What causes this green hair algae to grow up by the way? I also got a little of it but nothing too hard to handle by hand till now..
Hi there, I accidentally left the light off one of the tanks whilst away and yes, it affected floating plants....but the salvinia will revive as mine are reviving now I have turned on the light
@@Natquascape with that knowledge just pop them (surface plants) over into another tank should the be a blackout need again..... Though this was a pretty convincing proof that it can work.... Other than the stem plants taking a slight hit... I bet it was like unwrapping a present taking the covers off. 👍🏻
Top video buddy.
Cheers mate! Goad you like it...much appreciated

Great video! Glad it worked out for you.
Thanks you, the tank is green algea free even after 11 days
Thanks for this video. What is the reason for the cling film before the black bag over the top? And the aeration? Thx

How many Amano shrimps you got in that tank?

Very true however, after 10 days I have not seen any green algae. Dont know what the trigger was, I think its something in tha water.
Will this method affect salvinia

To much light. That algae is easy to fix
I feel you Emma....light is always causing the issue....I need to adjust in all my tanks.
