I've recently restocked my pond from a local supplier. Within the last 3 weeks, I've purchased approximately 17 Koi from this vendor. These fish all range in size from 4 inches to 10 inches (most are about 5 or 6 though).
Last week, I noticed one of them had 2 pretty prominent, white "salt rocks" on its tailfin. I'm pretty sure this is Ich. After conducting some research online, I found a product called Knockout Plus from Crystalclear. I've been dosing my pond since Friday with this product. I chose this product because you don't have to remove the biological filters etc.. and you can dose the entire pond simultaneously.
I lost one of these fish on Saturday. Now, at least half of my fish are flashing and most of them are "hiding" or laying on the bottom of the pond. I fear the situation is only getting worse.
Before I list out some questions, here are some vitals stats regarding my setup:
Water quality
* Ammonia Level (pond): 0
* Nitrite Level (pond): 0
* Ammonia Level (tap water): 0
* Nitrite Level (tap water): 0
* Ph Level, pond (If possible, KH, GH and chlorine): 7.6
* Ph Level, tap water (If possible, KH, GH and chlorine): 7.6
* Brand of test-kit used and whether strips or drops? API Master Pond Test Kit, drops and strips
Other useful information:
* Pond has a mature bio filter system in place. The pond also has many plants. No additional aeration though. I ordered a dissolved oxygen meter yesterday and will have it tomorrow. Once I have it, I'll post my dissolved oxygen levels.
* Water temperature? Around 60 F, sometimes up to 65 F. I live in North Dallas so the Temp swings are pretty dramatic. Right now, 60 F is pretty average.
* Pond size and how long has it been running? Approximately 1,400 gallons, 3-year old pond. Pond is about 11.5 X 10 x average depth of 2 feet
* What is the name and size of the filter(s)? Savio Compact Skimmerfilter (CSW085) with Savio Livingponds Filter (F070). Recently installed ultrabright 28 Watt ultrabright UV light in the skimmer.
* Pump is pushing 1,500 GPH through the waterfall filter, then cascades down rocks a couple of feet before going back into the pond so plenty of aeration
* How often do you change the water and how much? Approximately 20% per month. Sometimes a little more in summer
* How many days ago was the last water change and how much did you change? 30 days ago (1 week before adding the first batch of new fish). Changed about 50% as I was conducting my annual "spring cleaning" on the pond. Also removed all gravel from the bottom of the pond. I used to have about 3 inches.
* How many fish in the pond and their type? There's approximately 18 fish (not counting the 7 or 8 baby Koi, they're only 1 inch).
* What kind of water additives or conditioners have you used? Always use API Pond Stress Coat pond water conditioner. Removes chlorine and other toxic chemicals and helps protect slimecoat etc...
* What do you feed your fish and how often? Hikari sinking pellets
* Any medications added to the pond? Knockout Plus, beginning on April 21st.
* List entire medication/treatment history for fish and pond. Have only used Knockout Plus. I've only lost 1 fish over 3 years due to illness. Most got eaten by Blue Heron last year
Ok, now for my questions and observations:
1) Does anyone have any experience using Knockout Plus? Is this product legit? I only ask because I can't locate any information about what's it made of. Is it really safe for your bio filters etc... I'm supposed to use it for 7 days, my fear is this if it doesn't work, it may be too late to try anything else. Can I use some type of anti-bacterial remedy with this product??
2) As noted above, half of the fish are flashing. And they are now all laying on the bottom of the pond together. They've been doing this for a couple days now. The first 2 weeks or so, they were pretty active all day. Another interesting thing I've noticed is that the majority of them all seem to lay in the same area, usually facing the same direction, in a remote corner of the pond. They all do this except for 3 or 4 of them, usually after 6 PM or so. This morning, I noticed one of them was laying on its side in the middle of the pack. Not good. Minus this one fish, all the others seem to be eating very well.
3) The original fish that I spotted the ich on, appears to be doing much better now. Isn't really hiding anymore and is eating like crazy. The 2 white "salt rocks" are still there though.
Does anybody have any ideas, pointers or suggestions?
Ps... I'll post some pics tomorrow
