SRC Member chrislwp Posted August 28, 2003 SRC Member Share Posted August 28, 2003 JUst some experience sharing: Guys, I started cycling my tank mid of July, took 2½ weeks to complete with ammonia and nitrite close to 0, nitrate 25-50ppm. I started to add fish, more and more, 11 clown, 1x9" blue face, 1x9" blue ring, 1x6"blue tang, 1x3" yellow tang, and 7 angel fish, 2 lionfish, 3 damsel, and some other small fish.. total about 30 fish altogether. With an outbreak of ich and parasite 2 weeks ago, I put in 120 drops of MedicCure blue solution, overdose, whole tank blue, but according to instruction, i am suppose to put in 300drops (1drops per 2 liter). SOme fish die immediate, some fish body rot.. most fish suffer eyes cloudy. So today, I left 4 clown fish only, and going to die soon. NH3 and NO2 close 0, but NO3 75ppm after 50% water change. Till today my skimmer still collecting blue color solution in the container. I even use those denitrator pellet and 2 pieces of polyma filter to help remove NO3. I am wondering what is the main reason with the 4 activities below 1) overdose of mediccure 2) high concentration of No3 3) rearranging of liverocks 4) 50% water change 5) adding of sand Currently I have added 120kg of sand to my tank. Create a slight slope, with front 4½" and behind 8" of sand. Hope this can help in long run.. do not want such mishap to happen again..

SRC Member Chris Posted August 28, 2003 SRC Member Share Posted August 28, 2003 I think most possible reason is over-stocking. Nitrate at 50-75 ppm will not kill fish, neither will changing water. Could be the medication too. Quote I think (marine) therefore I am Link to comment Share on other sites More sharing options...
maze Posted August 28, 2003 Share Posted August 28, 2003 Wah... you really over the bioload. One 9" BF in yr tank is already enuf to..... Quote Link to comment Share on other sites More sharing options...
joncver Posted August 28, 2003 Share Posted August 28, 2003 ur tank has too much fish! overpopulated, disease outbreak is more likely to happen... Quote Link to comment Share on other sites More sharing options...
Sponsor dr evil Posted August 28, 2003 Sponsor Share Posted August 28, 2003 u are stocking too fast..........and over stock...... also, marinecure is not a good product. Many reefers have bad experience when using them..... Quote Link to comment Share on other sites More sharing options...
roidan Posted August 28, 2003 Share Posted August 28, 2003 your 8 inch sandbed will not be effective...the sand grain size is too big.....u need those sugarfine size 0 sand for it to work...and even if it does...results do not kick in fast....many many months before nitrate reduction takes place on merit of the DSB....

SRC Member pospeh Posted August 28, 2003 SRC Member Share Posted August 28, 2003 I agree with everyone with respect to overstocking. There is too much fish and you added them too fast. I am extremely surprised that your NH3 and No2 levels show 0 There must be something wrong with your test kit with so much bioload on your tank. What brand are you using?

SRC Member seamonkee Posted August 28, 2003 SRC Member Share Posted August 28, 2003 Overstocking alone is bad enoff... I also notice that in your old set up, you have moved the LR around... disturbing your LR too much will cause some LR die-offs and give your tank an ammonia spike... Also, moving your LR around with fishes in your tank can cause serious stress to your fishes making them sceptical to diseases. Quote Link to comment Share on other sites More sharing options...
SRC Member chrislwp Posted August 28, 2003 Author SRC Member Share Posted August 28, 2003 your 8 inch sandbed will not be effective...the sand grain size is too big.....u need those sugarfine size 0 sand for it to work...and even if it does...results do not kick in fast....many many months before nitrate reduction takes place on merit of the DSB.... Initial I have 60kg of grade 1 and 3 sand to fill up 3-4". Later on I added on another grade 0 X 40kg and grade 1 x 20kg Now total 120kg sand.. front 4½" and back 8" thick. So the top most layer is super fine. I know that DSB will only mature 9mths later, that's why I am using some denitrator pellet and polymer filter, and protein skimmer to reduce No3. Also change water occasionally. I have already build another small tank underneath my tank to keep macroagle. At this point of time.. I learnt my lesson and only add fish and coral slowly when necessary. Wait for the last few nemo to die first, wait 1 mth before adding again) I am also using a domestic long fan (ichiban brand $50+ with remote control and timer) those long stand fan about 2½ ft height to blow the surface.. Much cheaper than those motor fan selling in LFS..costing $70+ per small fan.. Not to surprise you with just a fan, the temperature reaches 26.8°C last night when I switch on my aircon.. damn cool. Normal day is 27.5°C. Only problem is water evaporate fast. Quote Tank 4x2x2.5 Link to comment Share on other sites More sharing options...
