We will pray for you Alfred. May you, your family and all of you in harms way be safe and sound.

 

God bless.

Alfred, how are you doing with the earthquake and tsunami?  We are concerned for you!

Hi Tokyo Alfred. Always a delight to hear from you.

I need to know more about what is going on in your system before I can offer any advice. How many fish and what size? What are your ammonia, nitrite, nitrate and pH readings? How much grow bed volume do you have? Some pictures would really help. Once you have all that I also encourage you to post this as a forum topic so you can see what others think might help as well - there are a lot of very smart and very experienced aquapons in here.

Hi Alfred,
I will be going to the US later this week to attend a wedding.
Did you want me to get you anything while I am there?

Did you already get that PH Test Kit?

Best Regards,
Greg

hallo alfred Fisch brauchen nicht viel sonnenschein am besten ist wen du deine eigene
ideen ausubst. remember amonia nitrite nitrate das muss stimmen und die wassertemperatur uber 18grad in dem buch from Dr.james e rok
ocy.die bacterie stirbt
unter 18 grad und ohne bacterie die transformation von amonia to nitrate ? manfred

Hi alfred,

Are you referring to CHOPS, if so please follow Murray's design. The one in my blog is just to illustrate simplified CHOPS, The water outlet on CHOP can be below surface if you have a strong pump and more water in the fish tank.

Its best to do as Murray's DVD since its his system and I'm merely giving brief explanation.

Hi Alfred,
I'm guessing here..

Are you making growbed from that fish tank ? If that is your intention its best to make a hole for the siphon. Because using U-pipe type of siphon on such will require you to have the top most part of the u tube as the upper water level of the growbed.

The u-pipe will be over the fish tank edge, this would not cause any siphon action unless its lower than that. You either need to make a hole at the bottom (for bell siphon) or on the side for U-tube (loop siphon)

Loop siphon may be difficult to get right, I have not experiment much on this (maybe next) to give concrete advise.

U-pipe and bell siphon, the syphon power is same because its depend on length of syphon outflow length to create the gravity/suction pulling force. However in Aquaponics the continuous inflow will add to difficulties in getting it right.

I don't see there is any problem with the acrilic tank you mention, however without further info from yourself, my explanation here are base on generalise situation.

Hope this help.

Regards.
Affnan

Hallo Alfred,
schön dich kennen zu lernen!
Tja 4-6 Stunden Sonne ist wirklich nicht viel. Ich bin zwar kein Crack, aber würde sagen, dass es schon besser wäre, wenn es etwas mehr Licht gäbe. Ich denke, entweder suchst du dir Pflanzen aus, die nicht so viel direktes Licht brauchen (Paprika, Tomaten, Karotten, etc.) oder du nimmst zusätzlich eine Lampe die pro Tag ca. 4 Stunden brennt. Allerdings ist das eine Menge Strom und mit einer Photovoltaik-Anlage wirst du das gleich e Problem haben.

Ich hoffe mein Kommentar hat dir ein wenig geholfen.
Wünsche dir viel Glück - bis bald! Viele Grüße, Ingo
