Flourite and GH, AND EI with increased water changes
OK my tap water is really soft. Out of the tap I am 7.0 pH, 3 deg. GH and 1 deg. KH. I treat with Baking Soda and Epsom Salts and age my tap. When added to the tank I am at 7.2 pH, 5 deg. GH and 3 deg. KH. Discus are in the future of this tank should I get it all figured out. Tank has been set up and cycling with a handfull of plants, normal gravel (hey did not know any better before going down the planted tank route) with Laterite (3-55oz bags for an 80 gal. tank with 125# of gravel), fish and running a store bought DIY type CO2 system.
So after much thought and research I have taken the plunge. My plants are due to arrive this week and decided to get real CO2 and a semi-decent substrate. After reading for a while decided I would mix a 50/50 Flourite with my gravel. I know it is not the best but we shall see how it goes. Also ordered was the Miliwaki SMS22 Controller and regulator. Spent today building a Rex Grigg reactor for my Fillstar XP3. The tank was bought and filled this weekend and CO2 stuff will be here Tuesday with Plants. Wednesday my additional lighting comes in to bring me to 145 watts.
So a lot of back ground for what?
Checked the chemistry today. Before now the tank had always lost GH and KH and ran at 3/1 GH/KH and a pH of 6.6 with the DIY CO2. No CO2 since new substrate and rearramgement at all with all my filters running (950 gph) and the following was the chemistry:
GH- 12 ???????
So according to the charts I am at 3.8ppM CO2 which would be expected.
What caused the huge rise in GH?
I change water 25% every other day for my Appistos and Rams. How long till GH comes back down? Is it the Flourite? Need it back down for the Discus.
Also how long to wait after I plant heavily till I start the EI dosing and what affect is the 25% everyother day going to have on dosing?
