shuks's 3 easy steps toward algy controll...

hay everyone. I've been in this plant game (and forum) for just over a year now. During this past year I've spent most my time battleing algy. I consider myslef a profeshional algy grower. I can grow every kind of algy you can think of. Recently, in the past month or so, I've finnaly got controll over my algy, and I'd thought I'd post my journy for other people going throught the same thing. Im by no means an expert because there are many people with WAY more experiance than me, but this is what worked for me..

#1 cause of algy: no1 and no2 spikes. If you dont know if you have ammonia or nitrite in your tank that should be the first thing you check!

#2 cause of algy: (this is the biggest factor contributing to my success) not enough oxygen in the tank! I know thoes of us who inject co2 want to keep surface aggitation to a minimum to prevent co2 loss. When I switched from my HOB filter to my xp2 canister filter I placed the spraybar about 4 inches under the water line to minimize surface aggitation. I had good circulation in the tank, but not enough oxygen was disloving in the water. My fish started to die (at night) and my plants looked like crap. After elemanating all other possibilities, I came to the conclution that they sufficated at night when the plants were breathing o2. I replaced my spray-bar so that it makes the maximum amount of surface aggitation that it possibley can. I noticed a drop in co2 levels, but I'm more than happy to crank the co2 up a little bit to make up for the diffrence. Almost imedeatly after I did this, my fish look 10 times more active and happy, and I had no more fish deaths since. A couple days later I noticed my plants looking REALLY healthy (like they did before I romoved my HOB filter) and I've had almost no algy what so ever.

#3 cause of algy: this is a common one that everyone already knows. Nutrient defficiency. If your running your tank high tech, then make sure your N, P, K, and iron levels are present. Also, probably the most over looked nutrients are magnesium and calcium. Dont assume you have plenty of both just because you tap water is hard. If possible, try and fined out the exact ratio of calcium to magnesium, then dose accordingly. I believe the most accepted ratio is about 3 parts calcuim for every part magnesium, but I dont think it really make s a big diffrence as long as there both present.

So, thats that... Hope someone can fined something usefull out of this thread. Just trying to give back to the community that has given me soo much. Good luck..

Is algy is the same as algae?

Shuks,
I noticed that what I switched to an XP1 from a Emperor 280 my plants really enjoyed the extra Co2 that was being retained in the water colum. I will watch out of O2 type difficencies though. Algea is slowly creeping up on my though

Peace,

sorry everyone, you'll have to esscus my spelling. Im probably the worst speller you've ever seen.

Ryzila: You would want to keep the co2 level the same if your running pressurised co2 (30ppm). All I know is that I was running a DIY co2 setup on my 75 gallon tank. At this time I was also using a "HOB" filter. HOB filters are best known for there oxaginating properties, and I still managed to get up to around 15 ppm co2 levels. During this time, I experianced almost no algy at all, just a little bit of green "dust" algy on the glass.

Basicly, as soon as I removed the HOB filter I noticed green thread algy started to grow, and my water tested positive for ammonia. I think that the lack of oxygen was hurting the plants as well as by bennificial bacteria collonies. The surface aggitation was so low that the plants, fish, and bacteria collonies almost suffocated.

So, I made as much surface aggitation that my spray bar can make. Bingo-bango-bongo, no more ammonia spikes, no fish deaths, and most importantly my plants grow much healthy.

I LOVE OXYGEN...

again, please escuse my spelling. I probably didnt even spell escuse right. If it wernt for spellcheck I dont think I would have made it past elementry school. I'd use spell check, but I just re-formated my comp and I need to install microsoft office. sorry.

I am unsure what you mean with NO1/ NO2 but if its ammonia and nitrite then thats NH3/NH4 (ammonia/ ammonium) and NO2 (nitrite).

Nice post. Don't sweat the spelling.

Another thing worth mentioning is that the tank needs a good supply of oxygen to "burn off" all the stuff that's in there polluting it. There's a lot of it too. Dissolved stuff, particulate stuff, all the detritus and whatnot. Taken together, it's called the biological oxygen demand (BOD). The higher the BOD the more oxygen that gets used up that way and is therefore not available for fish or plants.

As well as taking care of nitrogen, your bacterial filter also helps handle the BOD. The higher the BOD, the more the bacterial filter will have to do double duty and take care of this as well as nitrogen. Supplying oxygen through photosynthesis, an HOB vs canister, running an airstone at night, etc helps the filter cope.

Manual cleaning, diatom filter, better circulation,etc lowers BOD.

I agree, nice post Shuks. Your Arawana tanks are awesome. BTW, if anyone adds magnesium (aka epsom salts) and calcium chloride be sure to give the water column some time between additions. Otherwise they bond into calcium sulphate which is very slow to dissolve and can make a nasty film/scum on the surface - something which probably inhibits O2 as well.

thanks Wapfish and Betowess; excellent points...

Good call about the Epson salts and calcium chloride. I've experienced that problem before with film on the surface of the water. Looks like someone spilt gasoline in the tank. Took me forever to find out what the problem was.

Nice one Shuks. I just started down this road myself this week, so articles like this are really helpful. I am running a Penguin 100 in the 20 tall, with a Hagen CO2 kit (ladder and bottle). Will it have trouble keeping the CO2 up because of the excessive agitation at the surface? I have put the water level right up to the top to minimize evaporation and splashing, and also to maximize the light.

I dont think that youll have a problem reaching good co2 levels on a 20 gallon. Just try and fined a neutral point where there is enough surface aggitation to oxaginate the water really well, but not enought to dissipate your co2 levels under 15 ppm. Do you know what level your co2 is at right now? If low co2 levels become a problem, you can alwayse run an extra bottle of yeast and sugar. I ran 2 bottles on my 75 gallon (before I went pressurised) with a bubble ladder and an aquaclear "HOB" filter. I got exelant oxagination of my water and I still managed to keep co2 levels around 15 ppm.

No, I don't. I have a laborette kit from Tetratest that gives you a calculation of CO2 I think based on hardness and pH, but I would have to check it at home. This is my first planted tank, so it's a bit overwhelming at the moment. I didn't get the CO2 working properly until last night (I just set the tank up on Tuesday night, and Wednesday night.
