algae affected by temp?
Principal causes of
BGA are 1) dumb luck and 2) excess nitrates. Phosphate is a more likely root cause. Temp makes everything cold blooded, and one-celled, "go faster". Search the web for PMDD, or "Poor Mans Dupla Drops". Not so much for the formula, but it's development came from quite a bit of interesting research regarding algae. Bottom line, higher plants apparently store Phosphate, algae (being a 1 celled plant) has no place to store anything. If you maintain 0 Phosphate - algae can't get any. When tiny peaks happen (like feeding time), the "hungry" higher plants suck it out in far before algae "grow into it". Floating Hornwort, is my answer (bill has Phosphate in his tap - that makes bill sad) and good light. And, yea, use PMDD if you use fert at all. When you toss a handful of Hornwort, the key is you're tossing a chunk of Phosphate. Neat thing about it, when your water is in trouble it grows "real fast" and both sucks nutrient and shades the lower tank. Keep a tastefully blob bobbing around, if it starts to "explode", let it. When the top of your tank is well covered, to some depth, yank half. The deeper you let it grow, the faster the process works. If you yank once a week, you will eventually notice a week were the top didn't end up covered. Let that go another week, the yank half. Soon you'll notice it takes quite a few weeks to cover the tank. Now you can prune back and maintain a more tastefully sized clump. Arg, a tank 1/3 full of Hornwort, yuck. Well, choose, Hornwort once and again, or algae full time. ****************************** Dunter Powries wrote: Brian wrote in message ... All else being equal, will warmer water produce more algae? Blue-green algae in particular? Just curious, as I have more algae than usual, with no other parameter changes I know of besides temp. Yes. However, warm water probably isn't the proximate cause. Principal causes of BGA are 1) dumb luck and 2) excess nitrates. |
