Backyard Aquaponics
A place to discuss aquaponics

KH is now holding at 6-7 drops, I added 4 more oz. GH is now around 10-11? I guess I'm getting closer.
Nitrites up a bit to .5. PH was at 7.77 everywhere. Same on both sides of mbbr?

Small koi are eating. Big guys not much. A few of the small one in the big tank did take a few pellets. Big ones haven't come up in a several days. I'm giving them more room. Like Ryan said they aren't used to having clear water, and they are spooked.

Gh dropped back to 7 drops, I added more soda. PH dropped a bit, and nitrites seem to be holding around .5

Had to replace some sensors on 1 of my trucks today. MAF and TPS. Mass air flow was quick and easy. TPR required removal of the throttle body to access the sensor. Took a few hours, but it's running good, and the local mechanic wanted $300.00 for the job. Penny saved...

RAS system looks optimistically good. PH around 7.8, stil low on KH. Big koi ate some last night.
Added some more Bicarb, and fed all fish this AM.Will monitor and keep updated. Nitrites are under .5 and seem to be edging down.

Cleaned netting filter in AP for the first time in I can't remember(4 months?) It was very clean, just had a few inches of sediment in the bottom. I'm assuming it went anaerobic and was dropping nitrates(20ppt) When I was cleaning it more often, the netting was way dirtier. seeds in GB's, and I've got basil, lettuce, and toms popping up. The Malabar spinach is going crazy...pretty invasive stuff.

I haven't cleaned my netting tank since March this year.. Probably should take a look to see what is going on in there. Maybe it's reaching equilibrium were microbes consume any fines coming in. I have not noticed any measurable deduction,in,my nitrate levels. Then again I am overstocked with fish to plants.

Sounds like a good day for you over all coach!

Setback this afternoon. After AM feeding, nitrites are back up over .5. PH is about the same..7.8-7.85
Dosed again with 4 oz. bicarb, and will check again later.

It WAS a good day Swede.

Uh oh

Pretty much what I would expect after you cleaned the netting tank (especially with all the sediment in the bottom). The other filtration has to pick up the slack because the netting tank was getting rid of some of the nitrogen before.

No, that was in the AP system, not the RAS.

The ammonia is still at zero. Ryan said as long as that's the case, keep dosing and it should balance out. The PH in the inflow of mbbr is 7.8, and about 7.67 coming out, so some pretty good activity. Hopefully, the nitrite will drop back to .25 tomorrow. Small koi are eating pretty good, big guys are very shy about rising to eat.

NFL opener is on. Glued to the TV for next 3 hours. Love football. Love sports, but football, hockey, and soccer are my favorite to watch. Besides tennis of course. Nothing beats a good linebacker smack down on a running back coming through the A gap. Good stuff!

Chris when i kept Koi i use to train them to feeding times,i would put my fingers in the water and give it a good splash,then drop the food in and walk away watching from a distance,over a period of time the Koi would learn to associate the splash with food and slowly but surely would come to the surface,eventually coming right to my fingers for food.The was one other method and that was to use a Chagoi Koi,these were the easiest to tame and train to the food,they would always be the first to rise eventually bring the others with them,if you could locate one or two of these they could be permanent in your tanks and i reckon they would help any new intake learn to come to the food quicker,its the competition thing if they see one doing it they will follow.
Still got all my fingers crossed for you ....

I missed that, carry on

Thanks Scotty!

PH up to 8.07 in system, 8.01 in mbbr. KH around 125...still low. But PH is getting too high??
Nitrites are a bit lower, but still closer to .5 then .25. Ammonia still at zero. No feed till later. The roller coaster continues.

I'm trying to figure out what my 12 drops in the KH test means, anyone know where I can look?

Should be on the sheet that came with your instructions. I think each drop used in the test is the equivalent of 17 or so mg/L of CaCO3. I found this sheet which relates the units to OH- ions, it might confuse you or might help

Ph is down to 7.8, 7.7 coming out of mbbr. Ammonia zero, nitrites down to around .25. Large koi ate a little, small are eating pretty good. I fed once moderately at 5PM. Dosed with another 4 oz of bicarb, and turned the air up in mbbr.

Long day working today, and it was hot...about 94F, with heat index around 112. I hate Florida in September. Everywhere else will start to cool down, we'll swelter till October. But, cooler weather will come.
