VERY High KH and GH --- looking to reduce....right?

Hi, I have recently added RCS to my planted tank with glosso, anubias, and some moss.

I was doing everything blindly, with no test kits, besides a CO2 drop checker.

I have 40w x2 PC, green drop checker (pressurized CO2) and Eco Complete.

Here are my specifics:

pH6.6 -
GH 360 ppm
KH - 350 ppm

They are a nutrifin test kit.
Per Hoppy, I haven't been able to calibrate them, but did test my RO water at the house and the GH and KH are MUCH lower (20 ppm GH and 30 ppm KH)
So I could add RO water to the tank to bring everything down when doing a water change, but want to do it slowly, right? Because of the RCS?

I know they are not like CRS, but still...

I wouldn't worry about it, unless your ready to mix and test to find what you want in the water, you're making alot of work for yourself. Cherries do fine in hard water, much harder then waht you have listed.

Hmm. My RCS do just fine in water like that. They are the cockroach of the hobby. If they are doing ok, don't fix whats not broke.

If your going to switch anyway, then just do all your future water changes with the RO water.

Well....(and not to hijack my own thread) but I have recently added them, and they aren't eating or looking all that good, but they are new....

Also, you are saying I could use ALL RO water?

That is really different pH, KH and GH....I might do it slowly, I only have a 1-2 gal RO tank here at the house, and it is a 14 gal tank, it takes forever to get a gallon...i guess I could do it slowly....

Thanks!

How long has your tank been cycled? How long have they been in the tank? Any other tank mates?

Thanks C -

Short answer, no other tank mates (except snails) and tank has been up for over a year, in some form.

Long answer, its a little bit of a long story...tank has been set up for about a year, 14 gal, HOB, spiral fluorescent 6700K lights, Seachem fluorish, and DIY CO2. Growing Anubias (not sure what species) glosso (kept growing straight up) Vals (unsure of species) and Moss ( you guessed it, unsure of species) in pebbles.

Then...switched to EcoComplete and Current USA PC 2x40w - plus pressurized CO2 had some tetras, RCS, otos and a couple cories, things were good and growing, plants were pearling, etc.

THEN...disaster!!! 2 yo turned off powerstrip when i was away...CO2 kept pumping (i leave it on at night) and we lost about 70% of the fish. those that recovered were ok. then a couple weeks later, same 2 y.o. dumped a bottle of Fluorish Iron into tank and a bottle of fluorish, wiping out the rest of the fauna.

So I took most of the water out, added new, and ran tank by itself (just flora) for 4-5 weeks.

Added RCS on Monday (4 days ago). They seem sluggish compared to old ones. Too much CO2? I have a Red Sea Drop Checker, but in the past, even when green, I changed the solution and it was yellow...

thoughts?


Thanks for all your help/input

Have you tesed for ammonia, nitrites and nitrates? By running the tank with jsut plant no fauna you may have triggered a mini cycle

Sounds like you are likely cycling again. Do some regular water changes.
