i am also a beginner, iv had my pond since oct 2009 and ive recently had a bad problem with my fish geting fin rot and also 1 fish had at least had bad cotton mouth, i think i have had about 7 fish die from it. i also seem to have a problem with algae, my waters a green colour, i have now set up a new pond pump and filter to cope with 700 gallons an hour, my pond is approx 350 gallons. i have also installed a u.v. filter aswell, i was wondering if anybody can give me any tips to keeping algae and the disease down? the pond gets about 4-5 hours of sunlighta day?
I know this isn't African Cichlid related, but I thought I'd go ahead and answer.
How many fish do you have and their approximate sizes?
I have a 200 gallon tank with koi/goldfish right now (4,6 inch koi and 4, 4 inch fancy fatty goldfish).
[I'll be converting my 8 person hot-tub (700 gallons) to a pond this springs/summer; so don't worry!]
Anyways, I had as many as 10 koi in my 200 gallon tank. I noticed I had a lot of minor bacterial infections that wouldn't get any better. As you can tell I lost 6 fish (4 koi in tank). I attributed this to bio-load problems (even though I have about 1200 gal/hr filtration).
I would get more filtration in the form of bioballs/bio-media; do large water changes on a regular basis. There's a guy in my neighborhood with a 10,000 gal pond. He has a koi filter/Box that is 8 feet long and 3 feet wide, 1 ft deep. It's filled with pea-gravel though (beneficial bacteria grows on it). He has a substantial amount of koi in it and doesn't have any illness problems.
For the algae, there's a blue dye that you can buy that makes your water look awesome, and also prevents algae from growing. You can buy it at Petsmart. If your not into the dye, there's also chemicals that kill algae. I used AlgaeFix by AP that has worked well for me and hasn't had any ill effects to my fish. [I'm assuming your UV filter is powerful enough for your tank. For a 350, you'll need at least 10 watt bulb; maybe buy a more powerful pump to increase water flow(maybe 1000+ gal/hr)].
Hope that helps. Good luck !!!
