This two big toxin exceed the ammonia in aquarium and nitrite mark is most person raise bad fish or die often piscine prime cause. Because this wants to had been done,detect regularly the job of water quality, when the position that discovers a fish especially is unusual. Once discover the toxin in water exceeds bid, should be located in manage in time so. Prepare to judge the reason that exceeds bid even before this, with suit the remedy to the case.
One, open crock toxin newly to exceed bid
New open aquarium to arrive build whole nitrify system to need the left and right sides 30 days, control the toxin inside the crock to be able to reach highest peak in the 15th day among them. A lot of fish friend are impatient, did not tend in crock endotoxin 0 when below advocate fish, cast in great quantities feed. This burden with respect to system of can aggravating nitration, restrain the growth of nitrify bacterium, extend crock time. To this kind of circumstance should:
1, below conditional circumstance will advocate the fish moves piece;
2, increase the frequency that change water second, clear the organic matter such as bait of the incomplete inside the crock, excrement and urine;
3, inside the crock if have a fish, should stop to feed feed 1 week;
4, can old cotton of have the aid of (include the filter capable person such as annulus of pottery and porcelain) open a crock, but need to avoid old cotton to carry bacterium;
5, can join nitrify bacterium.
2, did not clean filter material for a long time to cause toxin to exceed bid
Many organic other people is enclothed to be able to restrain the growth of nitrify bacterium badly on filter material, the ability that brings about minute of alexipharmic element thereby drops to break down even. Clean filter material namely to what this kind of circumstance should do. The right way that filter material cleans is to use former crock water to wash the organic matter rub of filter material surface clean can. Boiled water of avoid by all means is hot, insolate, soda acid dip is washed etc, these methods can kill the nitrify bacterium on filter material thoroughly, make old filter material direct turn new strain into material.
3, filter the poison that systematic weakness causes exceeds bid
Filter water transport material of small, filter flow of insufficient, water pump is little etc is cause aquarium to filter the reason of systematic weakness, filter in aquarium the fish below the circumstance with insufficient system falls ill only, dead possibility is very large. Accordingly, the size that should consider aquarium when building a crock installs what match to filter system. Strengthen aquarium namely to what this kind of circumstance should do filter system. Specific measure includes the filter on bucket of the filter outside increasing, use trickle, make turn over essence of water sprite of gaslift, configuration to wait, still can change the water pump of large flow.
4, the poison that the drug inside the crock causes exceeds bid
Major fish medicine can cause serious blow to nitrify system, especially naked crock. At the same time filter material has adsorptive capacity mostly, the medicaments remains after stopping drug keeps clear of very hard also. Ultimate to this kind of circumstance means of settlement is to should avoid advocate crock drug. If must advocate crock drug so take filter capable person before drug put in pail, add oxygen and put a few small fish. After waiting for cure to end, do a few times change water greatly, again crock of filter material replace in, put remain of medicaments of activated carbon adsorption at the same time.
What the water quality that we often say asks the problem is main is the toxin in water exceeds mark issue, pisciculture raises water first, tell should build good nitrify system first namely, the ammonia in assuring water and nitrite content tend 0. Above method can solve the toxin that in raising a process, encounters effectively to exceed mark issue, the hope is friendly to the fish people helpful.
