    How to test CO2 levels without dropchecker

    I have always used a KH test kit, checked that with a PH test and then via a co2 chart. The charts can vary, but you get a good idea of what your co2 is doing. I've never heard of what George does. I would wonder how reliable this method was for most people. Test kits and co2 charts are how I...

    TMC/D-D regulators

    I like the TMC solenoid/regulators. My only gripe and I passed it onto the big guys at TMC them selfs when I was at Interzoo this year, is that the solenoid needs to be twisted around. I found that you had to have the regulator upside down to get it to fit on the bottle. Such a silly mistake. I...

    drop checker confusion

    Your tank water could naturally be acidic and no matter what time of day it is, it will still show yellow. The only real way to get a more accurate measure is to do a PH and KH test. In my experience, you can still add plenty of Co2 even if the drop checker is yellow, providing you know what...

    Stainless steel diffuser

    Swish bit of kit. No breakages either. Great idea and I bet it looks great. Cheers.

    what determines the capacity of a diffuser?

    The way I see it is this : Lets work with a 35L tank say, nothing to big. If you put around 1-3 bps of Co2 in to that tank, that would normally be the right amount - thats what you would be aiming for right! So you compare pumping 3 bps through a Rhinox5000 ( approx 4cm diameter ) as a pose to...

    D.C changing colour

    Hi Paul, If it were me, i'd find a space at the opposite end of the tank away from your diffuser to host your drop checker. Find the happy medium by getting the color to what you want. I aim near the yellow if the fish are ok with it, but if your not happy with that, then stick to a pale green...

    Really really struggling to get sufficient CO2 diffusion

    You lots me about here......... :lol: Where does this non Co2 gas come from in your filter, if its not Co2 excess? Is that the impeller basically bashing the hell out of the water releasing ( dissolved ) O2 out of the water? But many of us put our Co2 under our inlets, so thats bound to be a...

    Really really struggling to get sufficient CO2 diffusion

    Hi mate, Im no way a chemist, more the artist, but going by the Co2 charts. If the PH is 6.4 say and the KH is 2, then according to some charts, thats 25ppm. Could you not just add KH up providing the PH stayed the same? Having said that.........does increasing the KH naturally increase the...

    Really really struggling to get sufficient CO2 diffusion

    Hi, Do not dispair. Are you getting algae or poor plant growth? If not, then theres not much to worry about. Have a look at how much water surfice turbulance you have and try and drop that down a bit. The other thing you could do is up you KH, by adding KH up. This will give you a higher Co2...

    Fluctuating carbon levels

    Like everything in the planted hobby, good routine is vital, but some methods with tolerate the odd lacks day, ADA full system fro example. I would advice against doin it, but forgetting the odd day shouldn't cause you to much bother. Cheers.

    Advice/ opinions on co2 reactor

    The cheapest, but perhaps not the most efficiant reactor is your filter its self. Buy a cheap Co2 stone or similar and place it in or as close to the filter inlet as possible, job done! Or even cheaper, put the open end of the Co2 line into the filter inlet, job done! I doit, and its very...

    co2 is scaring me!!! i got kids man......

    If your getting it from TGM one of thier policies is to talk through the whole system, how it works etc. They get it out the box and explain what all the bits do and how to use them. You will be fine and they are all safe as houses. As for ferts etc, we can help you with that. If your keeping...

    Is this right?

    Its hard to tell, but by looking at it, i would imagine that the co2 bubbles would by-pass that hole anyway. I think the hole is there so that it allows water into the tube that your bubbles travel up. By doing that you will clearly see the individual bubbles and be able to count them, they will...

    Forget ADA prices for fancy Co2 valves, speed controlers etc

    Have a look under, http://www.pneu-store.co.uk/ *Valves *Fittings/Tubes *Flow/Speed controlers All the things a ADA charge a small fortune for!! This is what UKaps is about, finding the things us guys/gals want, and for less!!!! Pat on the back for ones self! Cheers, Graeme.

    missing a trick

    If you've based your watts on UK gallons, then your even lower on light than first though. Work out the tanks liters, divide that by 3.8 to give you US gallons, on which the watts per gallon rule works and then divide your watts into that new figure.I think it will be even less than your 1.8...

    missing a trick

    Hi, Im not a chemist, but from basic chemistery, your stats look fine,your water is very hard, this could be why your not seeing pearling. If i remeber right, and im abit sketchy on this so forgive me if im wrong but, The higher the KH then the more Co2 is needed to match it up to the ideal ppm...
