Well, again, why not make life easy? You could do the carbon cartridge thing or you could just squirt a few drops of Typical Dechlorinator while the water is being added to the tank. It works instantly.Always Broke said:...Off to find out about 10" water filter cartridges for these massive water changes...

ceg4048 said:Well, this is child's play compared to what you have already done. Just pretend this is a 200 USG tank. If that's the case, then the dosing scheme is just 10X the dosing for the reference 20G tank.Always Broke said:...I am going to use the EI method.This seams the best way forward for me I think from what I have read and doing 50% water changes is no problem. Now where is the best place to get what I need. Could someone give me a list in plane English that I can understand. I still am unsure of what quantity's to mix and also feed.
Sunday – 50% or more Water Change then dose [2 teaspoon KNO3] + [1 teaspoon KH2PO4] + [2 teaspoon MgSO4]
Monday – 1 teaspoon Chelated trace mix
Tuesday - [2 teaspoon KNO3] + [1 teaspoon KH2PO4] + [2 teaspoon MgSO4]
Wednesday - 1 teaspoon Chelated trace mix
Thursday - [2 teaspoon KNO3] + [1 teaspoon KH2PO4] + [2 teaspoon MgSO4]
Friday – Rest
Saturday - Rest
Now this assumes a sump volume of zero. To make the adjustment for the sump simply determine what percentage the sump is of the tank and add that percentage to the dosages above. So lets say you have a 50G sump. If so then that means you need to add 25% more of everything - instead of 2 teaspoons KNO3, you'll need 2.5 teaspoons.
These are just your baseline numbers. You would adjust up if you note deficiencies or you could adjust down to save money if the baseline numbers work right off the bat. I'd buy the 2Kg bags first.

Always Broke said:Been finishing off the mechanics of it all.
All the sump is finished
This is my home-brew water change and top up system The relay on the right is the Circ pump control .It stops the pump when the sump level drops and the restarts it when it has risen again.
The one on the left is the water top up. It is operated by the top float in the sump.
the one in the centre is there to stop the auto top up working when the water change pump is running.
All simple stuff really but super reliable
These are the 3 float switches that control it all. Top one is water level control
Bottom two are circulation pump control. When the timer sets off the water change pump , the main circ pump still pumps water from the sump to the tank thus lowering the level in the sump.
First the auto top up float drops but the solenoid dose not open as the water change pump relay has disconnected it. Then the middle float drops, the pump still runs until the bottom float drops. The pump then stops . All the time the water change pump is still emptying the main tank.
When the bottom float drops the circ pump stops. The water in the return pipe drops back to the sump ,raising the level a bit. As it is not enough for the middle float to raise the pump dose not start.That is the reason for this float to take into account the water level going up after stopping the pump. When the timer stops on the water change pump the solenoid valve is reconnected and starts filling the main tank. This fills and overflows down the weirs into the sump where it the raises the circ pump top float and starts it going again. The level continues to rise until the top float lifts and cuts off the water feed. Water change complete. Simple
Re did the Co2. Spent ages playing with it. In the end it work just as good by injecting it into the input of the return pump.
This pump is 10,000 ltrs per hour at 110 watts.
Also made a new bubble counter. I will machine up a nice stainless cap for it when I have time
The timers are fitted. Just awaiting the lighting unite to plug into the two on the left.
the first one on the right is Co2 . The second is water change. By adjusting how long this is on for I can alter how much water gets changed. Set to change 50% once a week at the moment. Need some tidying of the wires yet.
This is the water feed from the solenoid valve for auto top up and water change. Heated to around 26* by the combi boiler
These are the Syphon breaks . the closest one is the pump out from the tank to waste for water changes The other is the main pump return .
I have just got the new weir covers to make when the black acrylic turns up , box in the water change pump and make the new spray bar. Light unite is on order.
Should all be good to go by next weekend .
I bought some 3mm PVC sheet and cut it to size for coloured backgrounds The wife wanted blue and I wanted black At the moment they are blue but I can turn them around and they will be black . They just sit behind the tank with some foam pads keeping them pushed against the glass.
Oh and still waiting for Parcel force to pick up my wood I bought

Exactly. How easy was that? It is child's play after all!Always Broke said:So for my liquid mix I can do the following for a 4 week batch
24tsp KNO3
12tsp KH2PO4
24tsp MGSO4
added to 1200ml water and dose 100ml per time
And 8tsp of trace added to 400ml water and dose 50ml per time.
Its all becoming clearer . So I then adjust the quantity's until the plants are happy .
