I just went through the same thing with my water. I talked to a very knowledgeable fish store owner who advised me that short of buying a uv sterilizer the only other cure would be to remove all my fish and bleach the tank, equipment and plants (in a seperate bowl for 2 mins then immediatly put them in a bowl of water with a heavy dose of water conditioner) and then rinse the tank and equipment very well fill with water and add 15 times the declorinator and replant your plants and start the tank over. The only problem with this is you will have to recycle your tank.
ehhhhhh I dont really wanna use bleach ever again with my tank, i had a bad experience with it before (bleach dip with plants) and the whole thing of cycling the tank again, dont think its that worth it.
So, my suspicion is this: About a week before this started, I added 52 more watts of light to my tank, might have been an overload for my DIY co2. My lights are on a time and on for 12 hours a day.
Hopefully I'll up the amount of co2 and add stability, should take care of. I almost never see people that have pressurised co2 have algae issues.
I've done a blackout before and never had a problem.
Anyway, I bought a used setup off craigslist that included a 40g Tru-Vue, stand, 5# co2 tank, Pacific Coast Regulator, and a Coralife 36" 2x96w Aqualight. I paid $200 for all it.
I'm going to sell the Aqualight on ebay(I already have one extra sitting next to my tank, my wife would kill me to have two). That should bring in between $50 to $100. I'm then going to sell the tank/stand on cragslist for about $75. I say low end, I make back $150 and, after it's all said and done, I will have paid $50 for the co2 equipment.
The regulator is a Pacific Coast regulator. I have one complaint about it. The regulator is preset for downstream pressure at around 35 psig. It has a built it flow controller and I also added a 3 port manifold and Swagelok needle valve, but this high of pressure makes all flow control suck. I'm going to have to get a metering valve to really cut down the flow before it reaches the needle valve.
lol nice way to actually profit.
I found a problem with my diy co2 that mightve been the cause for green algae but not 100% sure, basically once i setup the bottles i dont really pay attention to them since i know its going to bubble soon.. well this time i guess i didnt pay even more attention and didnt factor in that the cold room temperature will be effecting the mixture. Normally i have a nice big stream of bubbles coming out of the wooden airstone but this time it was a fraction of that.. So today i placed the bottles in a tub with warm water and what do you know... it started bubbling like mad again. Will have to find a way to keep the water there warm (dont have an extra heater)
a pressurized system wouldve been so much easier to deal with......
