HELP! NastayNatron's tank - Page 2

yes, good sign.
make sure the return pump is running and all powerheads are on, do a water change if you can.
the high ph is a worry, what is it now?

How is it going? is it clearing up?

One thing to make sure is that all the pumps are on and circulating water. Odd to lose fish from much more than the basics of water movement and temp/salinity. So as long as there isn't a pool of water on the ground, salinity should be the same. Temperature is easy to check, so just make sure there's lots of water turn over.

Did the skimmer cup overflow into the tank? that would cause it to be cloudy and also cause a nitrate spike, starving oxygen.

Did a pump fall off a mount and blast into the sand? that could release all kinds of nasty stuff into the tank.

It has cleared up a bit and the fish are still more active than they were when I got home. The pumps and powerheads seem to be working normally - it looks the same and has the same colour on the indicator lights as usual. I guess now I'm just concerned because I still haven't seen a few of the fish and I can't find their bodies either.

The pH has gone up a little bit, to 8.7, so that's concerning too, it sounds like. I think the temperature is within range though, it's 79.2.

The skimmer cup didn't overflow into the sump as far as I saw, and I've emptied it twice in the past 3 days, so that shouldn't be it.

Thanks again for all your help everyone,

that PH is too hi, what are you measuring the PH with?
are you sure the water is running through the sump and the skimmer is running, the bubbles should be half way up the cup.
do you have an air pump and airstone you can put in the tank, this will help lower the PH.
vinegar will lower the PH instantly, you can add a tsp full of WHITE vinegar to a high flow area in the sump and lower the PH.
you need to find the reason for the hi PH, if it continues to climb you will lose everything.

I'm just measuring it with the general automation-ish system that he has. It's actually almost up to 8.8 now, so maybe I'll try the vinegar thing. I'm just a little nervous - can that be a problem when he doses calcium as well?

Cal_stir · #17 01-30-2012, 01:59 AM

yes but less likely, does he dose from buckets? check to see if the dosing pumps are running( the bar in the middle turning) or pull the tubing out of the sump and see if anything is coming out of them.

add the white vinegar to a high flow area of the sump, add it a tsp at a time, wait a few minutes and check the reading, it will probably take about 10 tsp before you see a sgnificant change.

check the dosing pumps or remove the tubes from the tank( they could be siphoning), it would be safer not dosing than dosing too much.

also, is he adding kalk to his top off water? if he is remove it as well and top off manually, the kalk would be stored in a reactor of some sort or mixed in a top off container.

i know this is all complicated if you are not familiar with it but you must find the reason for the high PH or it will go back up overnight.

I would do some large water changes and check all the water parameters.

lo_yyc · #20 01-31-2012, 12:49 AM

OK, so I tried some vinegar and so far nothing has happened, so I think I might just need to do a water change. the only problem there is that I don't really know how. I've seen Nathan do it a million times, but I don't know what I need to turn off and stuff before I do it. I'm also not sure if there's salt in the water downstairs, so I guess I might just need to mix it.

Would powerheads need to be turned off in order to do a water change?
