Backyard Aquaponics
A place to discuss aquaponics

And here's the Maxicrop site..... being a UK company I would have thought the product might have been available in Europe.

Perhaps email them molj

dthawk, a really valuable information, nice guidelines thank you very much!
and i was already supprised when i saw the growth rate at the start in my system, it showed me 0.4 EC, and the basil was already growing like crazy with half the fish i have now
i also noticed the same thing in RAS, you need very very veryy little nutrients if you learn how to reuse the solution and u work with lower ECs then in standard hydro, awsome growth rates!

well i read the lable, read how much u need for foliar treating and i gave 1/4 of that, still if i kept in mind the ppm conversion off volume percentage i wouldn't have done this. i know, stupid, i appologize to every being on the earth

the good news is that i was off for a day and today when i came back i checked my aquarium and it has cleared itself for like 60%
and the best part is that the basil is already growing new green shots!!!!!!!!

couldn't be happier with AP right now, the response time is simmilar to RAS systems, wooohoo, i love this!

i also had the same problem in RAS and it turns out that it was Fe too! so you helped me hit two flies in one stroke!

i think i'll look some more for the slovenian seasol version, since shipping costs are often related to me being lazy and not looking everywhere i could. good reminder on the email thing hehe

i'll post some photos in the next days, when things will progress some more, i know they will

thank you and good night!

Just google Fish Fertilizer theres plenty [squantos american ect]

food&fish, you gave me the perfect tick, i found dozens of products ment for aquarium fertilizing, farmaceutal grade and pretty cheap!
great tip!
good day

hey there AP people!

i have a question on tanks, now as i've read PVC tanks last as long as PVC pond foil does ~20 years

is this the cheapest way or are there other ways that are longer lasting and may cost a lil bit more?

now i'm thinking on building a 1000L tank that would support about 150 adult trouts 25 cm long that would provide me with ~2 kg of fish per month

i would need about 700-900L of gravel for about 4 beds(~200L each)

i was thinking on installing a 3000l/h water pump with a reserve pump plugged beside

now i'd like for the fish to survive the winter and with pumps on i think i should be out off the clear with a 0,8m height of tank, although it is suggested for the ponds to be at least 1,5m deep, what do you think?

now my calculations are rough, but still i'd like to know if i'm on the right way so i need your oppinion

thank you guys and girls!

Increase bed space if you can. Bed volume to tank volume would be better at 2:1. I do run mine at 1:1, but just because I have no more space.

Check head vs pumping volume. Is the pump you are considering 3000lph at 0 head? If so, it will move considerably less water if you are pumping up to the beds. I use a 5700lph pump with a 570l tank. It gives me enough capacity to turn over tank capacity 5x/hour plus circulate the water in the tank. Trout need higher oxygen than tilapia, so don't skimp on the pump capacity.

Yes, for 150 trout you would want at LEAST 4 beds of 500L of medium. Keep in mind the tank will need to have enough water in it to fill the beds, and still have water for the fish. Plus I would go for at least a 9000LPH pump for this application.

hmm i've read off those eqations, i use a 1600L pump for my 110 L aquarium. so in real my system's circulation is about 8-11×

i don't want to object the volume of the medium, but i use about 30L of lava rocks for my 110L tank(27% ) and i've had no problems with ammonia so far
and since my growbed is underwater, servs as a decoration too and a biofilter. my growbed is just water, so i'm not sure those ammounts of medium is actually needed.

does that come with bigger fish? my fish are like 4 inches at most
or does the gravel act as a ammonia buffer if the plants don't use all the nitrogen(defficiencies etc.)?

happy news, basil is growing definetly i'll paste a few pics...this is the hard part hehe, why can't i use image gallery?

i'm gratefull to all off ya that contributed, i'm really really happy to see some chlorophylle again!!


two more shots, i think things will work the mediumless way too

p.s. i found the personal gallery

Longer fish weigh more, so that's part of the increase in demand for filter. Visualize 10 guppies at 30mm in length each as compared to 1 300mm trout or tilapia. Also, we tend to use higher stocking rates than you would in an ornamental aquarium. Much higher. In English units (sorry, too early in the morning to convert), we aim for 4 gallons of growbed media to 2 gallon of fish tank to 1 pound of fish. All that bio-load needs plenty of surface area for the bacteria to live.

In reality, determine what your goals are, build what you can, and monitor the water quality until you learn the limits of your system.

true, haven't thought on that one, part of being young/stupid?
you'r really a great help to me janet, thank you
don't worry about the units, i have them in mind pretty much

so it's like 2:1:0.5 ratio, interesting, my goals are to supply my whole family for starters, uncles, cousins, friends...etc. with veggies and fish, to spread the good food and the good word!

but untill spring i'll work and learn on my aquarium and grow some more herbs!! i'll prepare a clone of Rosmarinus officinalis, some parsley, some allium, looking forward to taste some AP parsley!

Hey Molj, glad things are on the mend.....

If people here can't help you with a problem... then I guess you'd just have to be so much of a pioneer that we'd have to follow you

it's a warm feeling indeed! a friend of mine said, don't try to reinvent the wheel man!

couldn't agree more with him:D

good to see your progress

I have 330 gallons of growbed media 120 gallon tank "including sump"

What would you consider to be a good ratio for fish with that? How many fish rather
