Aquaponic system Maintenance.. Dealing with a nitrite spike..

Have had a bit of fun trying to get some fluctuating nitrite levels in the system under control over the past few weeks but think I have it sorted now.. Made up a clip explaining how I think it happened & the steps taken to keep the fish safe..

Will be keeping what happened with this system in mind as I start to plan for the new tanks & beds that will be going onto the system.. Have already thought about altering the way the filter is set up to try & remove as much solids as I can before they make it to the grow beds..
I found both the folks on the Backyard Aquaponics Forum & Paul from Earthan group very helpful with the advice that gave .. Paul's site also has a great salt treatment calculator that might come in handy to some..

Thought I would post a bit of a look at how we managed to clean out the grow bed that was loaded with fish solids.. I think this is part of the reason there was a nitrite spike in the system in the first place..

Held off posting on the bed cleaning just so I could see the levels drop & stay stable for a week or 2.. I think this shows that the cleaning was successful in reducing the solids that caused the nutrient "spike".. 
Making the air spear was really easy & came in handy cleaning out the beds..

Thanks to Paul from Earthan group again for giving me the heads up on the design of the DIY spear..

How our Aquaponic system works...

Made up a bit of a clip on Sunday just showing how the aquaponic system is configured for now.. I think it will always be a work in progress as there will always be something to play or experiment with.. Have already got a few ideas on how the new beds will be made, arranged 7 plumbed up.. Just need to wait for some plants to wind down before I can start moving the bed to make some room :)»

Aquaponic radial flow filter cleaning & pipe maintenance..

Time to clean out the filter & also solve a few mysteries involving the murky water that appeared from nowhere previously.. The filter is straight forward & we ended up with some great liquid to put on the garden beds..

 
Was good to solve the murky water in the fish tank mystery from a few weeks back... Was a bit of a "facepalm" moment as I turned the pump off & back on before both previous cloudy water events.. I think the gold fish are the culprits as the majority of the solids should be cleaned out as the water goes through the grow beds.. Cleaning the feeder pipe from the sump is something that should really be done every second week I think... Getting rid of the goldfish will also help to reduce the volume of solids in the line so we will be looking into getting them out ASAP..

Aquaponic radial flow filter for solids removal..

Due to the continually high nitrite levels I thought it might be best to remove some of the waste load from the system.. While a system this size normally doesn't need a solids filter I thought it was the quickest & easiest way I could think of doing this.. It will also come on handy when the extra tanks are added.. Took a bit of playing with the pumps to get it flowing well but other than that it was a quick & easy build..
Would like to thank Paul from Earthan group for dropping off the Uniseals & for giving me loads of pointers over a coffee or 4..
The idea for this came from Earthan Group's DIY Solids Filter from their website..
They also have a You Tube channel &  Face Book page for those that are interested..

Aquaponics, Jade perch & a bit of a roundup.....

Aquaponic update…
We finally have some table fish in the Aquaponic system… We ordered 25 Jade Perch from ANFE & picked them up on Thursday the 12th of April… Just held off posting to made certain I didn't "loose" any ;)»

Aquaponic mishaps...

Spent the past few days playing around with the pipe work for the system after having a few HSM's (HOLY SHIT/SUGAR/SHIVA moment's) with the FT (fish tank) overflowing due to clogged ports.. The fish are eating the algal growth & the stray bits are causing blockages in the drilled out end caps of the SLO's (Solids Lifting Overflow) that feed the GB (grow bed) & empty back into the sump.. I added an "emergency overflow" port that runs directly into the sump as an extra precaution..   I was looking at increasing the size of the holes in the end caps of the SLO's but received a comment on the clip from a most helpful viewer that recommended  making slits in the pipes instead of holes & run them vertically down the uptake pipe so did them first thing this morning.. Thanks "youronnit" 
A make shift cover was made up to help keep sunlight out so that will hopefully slow the growth of the algae..


 New grow beds & pipe work..

Have picked up the extra pipe needed for the grow beds but ran out of time this weekend.. I already have the bell siphons & enough 1" pipe to make the returns to the sump so hopefully some progress will be made this week.. Once I'm happy with the set up the GB's will be lined with black plastic on the outside (to stop algae growth)  then set in place.. Would like to fill the GB's with clay balls but due to a change in state government, B will be bumped down a few pay levels **zips lips so as not to rant then kicks soap box away** so it may mean a change from clay balls to rock for one of the GB's.. Might bring them on line 1 at a time as I think there are enough clay balls leftover from the old barrelponic system for 1 GB so we shall just see how we go..

Week in the dirt patch...

On Thursday we had whole house water filter system installed.. As chlorine & chloramines (found in most town water supplies around Australia) both indiscriminately kill good & bad bacteria/fungi we are concerned about using tap water that smells like its come straight from a pool on the garden beds... The system contains 2 coconut carbon filters as well as a pre filter that will remove the larger particles giving the carbon's longer life spans.. The main aim is to remove as much chlorine & chloramines from the water in case we need it for emergency top up water for the aquaponics.. It will also mean that we won't be killing off any of the beneficial mycorrhizal fungi we have been adding into the beds over the past few weeks when we have been sowing seed..

Made the decision to order some Veggie netting from Net Pro on Friday & it arrived 1st thing Monday morning (today) so will need to knock some frames up this week.. White cabbage butterfly eggs & a few small caterpillars have already been removed from some of the kale & cauliflowers in the patch.. Will also be used as a 20% shade cloth during summer which is another bonus as we have been looking for a lower % shade cloth..

Sunday saw us planting out a few seeds & 9 broccoli into the beds.. (Full list in Planting Diary)

Friday also saw this little feller finely emerge from a chrysalis...

Not sure of the variety as of yet but have set the task to our eldest as part of her studies for Monday..

 


Until next time, have a good one...
