I am still loosing fish at the rate of one every two days. I don't think it is the water quality. I think there is something else going on. Any Ideas of diseases that I could have picked up from the second batch of 3 in fry that I got from Blue Beyond. Andy
LOL....I finnally got a chance to watch Murray's 'Secrets' dvd....there was that chart again !
Hmmmm.....I'm not sure if I finished watching all of the 1st one yet :-)
well Phewy! I've been using the 5 way dip sticks and an ammonia dip stick... have yet to get any sort of ammonia reading (maybe the barest little glimmer of ammonia is being registered)... definitely NO Nitrite or nitrate readings... system is about 3 months old now. I thought my ph was OK... dip stick showed very pale... well my hubby got out his pool kit and we tried that for a ph test...and heavens!! so pink it appears off the scale! uh oh! We have well water... no chlorine etc. Tested it out of the faucet - looks like 7.3 or so.. let some sit in a container for 4 days (no aeration, just glass container of water sitting for 4 days), tested that... and get a reading of 8.5 or so! ACK! That is also what my fish tank water is registering :-( My plants are growing, but are pale, yellowish and not very robust. I lose a fish now and then... though the fish are acting very frisky and happy, eating well etc... I just get a dead gold fish periodically. Now also have tiny baby tilapia and am losing a few of those daily - majority of them are acting quite healthy and active and eating well....
BUT I have this very high ph, and so-so plant growth (actually miserable plant growth compared to the plants in dirt garden). Everything I read indicates ph should drop over time... mine's rising. My media is hydroton and lava rock. My research has told me that both of these are neutral and should not be affecting the ph... (my test of water left standing in a container by itself, and water sitting with lava rock seems to support that as both waters yielded the same resulting ph... 8.5 or so)
I have a 300 gal rubbermaid tank for the fish, 3 growbeds (flood & drain) 1 is 4'x8'x12in deep and 2 are 3'x2'x 7in deep (2 small ones all hydroton, large bed is 2/3 lava rock and 1/3 hydroton). I have maybe 75 tiny tilapia and 50-70 goldfish a few koi, mosquito fish etc.... koi and goldfish growing fast!)
I need some advice please as to what I ought to do to mess with the ph.... the standard mantra of *ph will naturally lower over time* does not seem to be applying. Help please.
I am beginning to get algae growth in the fish tank and on the pipe openings where the water enters the growbeds and returns to the fish tank. It has finally gotten warm here and water is no longer diving down to the 50s at night, so, yeah. Getting some algae. Does algae affect the ph??
We washed the lava rock pretty well - it was rained on for 2 weeks straight, then we rinsed it a lot when we put into the GB... water ran clear when we hooked it into the system.
As for cycling... I'd think it was all cycled... however I have yet to have any Nitrite or Nitrate readings on my test strips. The test strips DID register nitrates in the water that the baby tilapia came in.... I added that water into my tank hoping to do some good :-) But so far - I have lots of fish, but apparently pretty *empty* water. Seems a bit weird to me
