I have a question about top off water. I have been adding about a 1/4 tsp of kalk powder to about 5 gal of DI water before adding it to the tank. It raises the PH away from a very low level for DI water. Is this an acceptable way to add water. The PH is approaching 10, but it is being added...

Greetings I have built a couple of pond filters and used 2" bulkheads for 1800 gph. I only used one and it carried the flow. You may have to get away from the idea of teeth and maybe use some plastic mesh to keep stuff out of the overflow. You did not say where the holes were. Are they near...

thank you for the info, I need something that will work on the inside. I do not know if this kit will work on the inside without harming the fish. I plan on taking the water level down to do the work. Has anyone used a kit like this one? Or are other ways possible.

I want to know if anyone has a method for repairing scratches in acrylic tanks. I have some in a tank in service and would like to do what I could to repair. Any help out there on this topic. :roll:

Is it a good idea to use 10K and actinic in equal values? Or since 10K has the blue spectrum should you use more 10K and less (wattage) of actinic lighting. Custom sealife has a smart lamp which is 50/50. Is 50/50 the proper mix? Lets hear what others are using.

There is a lot of information on the use of kalkwasser. I have some additional questions. Is it wise to use it in the makeup water? If so, how much do you put in the makeup water. I use a 44 gal vat of R.O. water for makeup. I mix up a couple of teaspoons of kalk in a gallon of water, let...

I am not sure if you will have enough light with just 2 MH, 3 would be better but if $$ are a factor plan the canopy to be able to add them later. Most vendors for a 180 would use a sealed top with a fan on one end blowing in and a fan on the other end sucking the air out. MH will put some...

With a tank 24 " tall, you need some kind of brace. If you take it out you could brace it with a 12" wide piece of glass across the tank in the middle and use a strip on the front and rear of the 30" run the way you were talking about doing this and as long as the 12 " strip across the middle...

You did not say if you had a acrylic tank or glass. If it is acrylic you would not use silicone at all. If it is glass tank and you want to connect acrylic to it I have used a product called Goop. I built some acrylic drains for a pond filter (indoor) and connected it to a tiled wall (same as...

The real question is how big is your tank? If it was not real large, say smaller than 150 gallons, I would pump out the water into a couple of large containers and move the stand out an inch or two. Then put the water back in the tank. It should take no more than a couple of hours and you...

I agree with everyone about the bulkhead. If the water level goes down with the bulkhead, you will only suck air. Also depending on what size pump you use, you may not be placing too much water across the refugium. Most of them are designed to have a lot of water moving across them. It...

Thank you for the reply. I have looked at two of the three articles but all those formulas send me into space. I will print them off and try to study them so I can understand. Most of it looks like a foreign language! Can you have a PH of 8.3 and too much Co2 in the system? The reason I ask...

I recently had a problem with a CO2 valve opening up and causing a large dip in the PH of a tank. I placed a powerhead and put the tube on it to suck air and turned it on full blast to drive out some of the CO2. In a day the PH came up to 8.3 and all the fish survived except one. I have...

GE only makes one type of silicone that is used for aquarium use. Silicone is used in all the products that say 100% silicone, but it is the additives that will get you. These are trace elements such as the mildew inhibitor which is toxic to fish. The only way to know if it can be used for an...

I want to pass along some information about drilling glass. Tempered glass should not be drilled - period! Old tanks are a gamble, but can be done - sometimes. How can you tell if the glass is tempered? If a tank has thick glass it is probably not tempered. 55 gallon tanks used to be made...
