Introduce Yourself / Newbie Post

Hi all. Newbie here.
Finally managed to get online after finding the registration email in my junk folder, D'oh  :-\
Interesting to read about all you successes and failure on here, loads of useful stuff I am sure once I get going on my system.

My interest was pricked by Aquaponics quite randomly having found a reference to it somewhere or another, I cant remember where now. My particular interest is to make the control system from a Raspberry Pi to control my Aquaponics system but obviously I need to set up a system first!

Plan is to initially use my existing free standing patio goldfish 'tank' (600+litres) to supply a grow bed and see what happens whilst I build the greenhouse and put together a system in spring 2018 and hopefully produce first Aquaponics crop in 2019. This will give me time to set it all up, cycle, and see whether its viable to maintain water temps for Tilapia or not. I work in energy and heat transfer so this will be second nature to me.

Tilapia seems to be resilient in terms of water temp and quality from what I read, as opposed to Trout which are a little more fussy. Benefits of Trout are availability and heating costs its seems, only problem I see is the irony of potentially needing to keep the water down in the height of summer. But there are methods to do this.

Anyway, looking forward to some useful exchanges on here and hearing about all your successes.

Water Quality / Re: High gH
« Last post by mh on November 21, 2017, 11:52:14 11:52 »
OK, well one year on I am pleased to report that the plants are looking much happier and are much more productive.  Reducing the gH to more normal levels and occasionally supplementing iron and potassium (with kelp meal concentrate) seemed to help - as well as taking a more active interest in the water parameters of the input water. 

What also made a huge difference was also adding a bit of volcanic rock dust into the system in the form of a small quantity of zeolite powder - plants quickly responded very positively.  Happier plants of course, also mean happier fish and nitrate readings have also gone down.

Have you checked your ammonia? API test kit is very useful and cheaper solution.

Well, nearly two years on, I'm pleased to say my system is running much better.  I've had no further fish casualties, good plant growth and regular tests show stable, good quality water parameters, including for ammonia & nitrates. 

After the incident in Jan 2016, I abandoned periodic flood & drain and have an additional aquarium filter in the fish tank running 24/7 for biological filtration, plus a slow (but also permanent 24/7) cycling of water through the plant media beds. Ideally, I'd like to just use one pump, but given the system is currently stable and running well I am cautious about tinkering with it!  I agree testing for ammonia is important & I've also heard the API kits are good.  Other aquarium suppliers like JBL, sera & Tetra also seem fine.  Thanks mh

Extensive care should be taken while transferring fish from one system to another.

Sudden changes in pH, temperature and nitrites/ammonia can cause stress. You may want to use water from previous system.

Also, dont ignore one moreparameter which is usually overlooked that is Dissolved oxygen

Sounds really interesting Craig, do you have any pictures or info as to how it worked for you? ;D

Sounds interesting Steve, have you got any pictures? What fish you thinking of using, and what size tank you going for?
