brilliant example of a planted tank

Should have said the green component is useless for growth. It is well documented that chlorophyll uses red and blue wavelengths only,

Actually it has been shown that a small proportion of green spectrum is used when the plants are given very intense white light. Don't know if I'd be able to find it, but we were also discussing it with our lecturer during our Optics module.

Thanx for the kind comments everyone.
Im really pleased with the outcome. Co2 was turned on for the first time today and EI has begun. I swear I can see growth already lol.

Could I urge you to start a journal in the planted journal section slim? It would be nice to keep a track of your tank.

Slim, tank looks great!! I spy a GBR in there too, my favourite


Andy I was a bit harsh saying "useless" as although the green spike is rejected by the plants there's enough other wavelength light to keep the plants going. Should have said the green component is useless for growth. It is well documented that chlorophyll uses red and blue wavelengths only, white LEDs tend to have quite a strong blue peak with not much red. Since you have optimised CO2 and nutrients your lighting demands are not so high, certainly getting some good results with low light!

The ADA tubes that loads of scapers are currently using are very very green!!!. I'm sure its been discussed before on one of the many forums I frequent that plants adapt to use whatever light there is and do not ignore green at all. quite the opposite. They utilise whatever is there by adapting to it.

If it were true that green was useless then there would be many tubes out there by now (and I am surprised there aren't with marketing teams always preying on the mythology) that ignored full spectrum totally and missed out the green spike. Or supplied solely Red or blue in a 2 tube combo.

Definately, iv been meaning to do one for awhile now.

Quick question. Is it normal for the drop checker to stay green all night even tho the co2 is off? I was expecting it to turn blue again. Co2 is set to turn off at 7pm so I assumed the levels would slowly drop.
I am using 4DKH solution and I do have slight surface movment.
Thanx

It should gradually get closer to blue through the night. maybe still a mucky greeny blue just before CO2 commences.

Also try not to put too much solution in the DC. Use a smaller amount and it will change quicker so try keeping it below half way on the chameleon types (1ml+2drops)

Oh ok thanx

Just thought it was abit strange that the drop checker was still lime green late last night and this morning.
Suppose as long as it aint yellow i shouldnt worry

Next time you clean it hold it up to the light and look very closely. I have had some that have a miniscule crack in them and then the tank water seeps in/solution seeps out etc. Not a lot but enough to render any result worthless.

Will do. The plan was to take it totally out the tank tonight after co2 turns off and see if it changes to blue after afew hours of it being out of water. In theory it should as itll be in a co2 free enviorment.
Also I did a PH water test with my api kit and it did show pretty much the same colour green as the drop checker. Strange.

Thats because the solution you are using is identical to the low range PH solution found in the API kit. I use 4DKH water and 3 drops of low range PH solution in mine. (Which i think im right in doing anyway!)

Yea thats correct. Thats what im using too. Anyway, I took mt DC out last night and it did turn blue after a couple if hours. It jus doesnt in the water. Dunno my water must hold co2 really well or something. Strange. You would think the co2 levels woud drop over night if it aint switched on.
